从零开始搭建springboot项目
1、新建springboot项目
一、
new-->Project-->Spring Initralizr Group:com.zb Artifact:zbook springboot version:2.0.4css
二、
将html
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency>复制代码
改为前端
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>复制代码
三、此时项目结构
maven clean一下，右键ZbookApplication运行，项目就跑起来了，就是这么简单，真正作到了开箱即用。java
2、RestFul Api接口
一、在controller包下新建HomeController
package com.zb.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HomeController {
@RequestMapping("/")
public String home(){
return "Hello, Zbook!";
}
}复制代码
注：RestController和Controller注解的区别是：RestController是返回的内容就是返回的内容，至关于加个@ResponseBody,而controller通常是返回的页面mysql
此时打开网页，输入 http://localhost:8080/ 就会看到Hello,Zbook!jquery
3、集成Thymleaf
一、
上面的能够看成是提供服务的接口，假设咱们要开发一个web应用，springboot默认是集成的thymleaf。 springboot是约定大于配置的，咱们来看看关于thymleaf的约定 （1）默认静态文件（js，css，jpg等）放在resources下面的static文件夹下面 （2）页面文件放在templates文件夹下面 咱们采用bootstrap来渲染页面，以下图git
login.html <!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8" /> <title>登陆</title> <link href="/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container"> <form action="login_in" method="post" class="form-horizontal" role="form" > <div class="form-group"> <h2 class="col-sm-offset-5 col-sm-4">用户登陆</h2> </div> <div class="form-group"> <label for="username" class="col-sm-offset-3 col-sm-2 control-label">用户名：</label> <div class="col-sm-3"> <input type="text" class="form-control" id="username" name="username" placeholder="请输入用户名" /> </div> </div> <div class="form-group"> <label for="password" class="col-sm-offset-3 col-sm-2 control-label">密码：</label> <div class="col-sm-3"> <input type="text" class="form-control" id="password" name="password" placeholder="请输入密码" /> </div> </div> <div class="form-group"> <div class="col-sm-offset-5 col-sm-4"> <button type="submit" class="btn btn-default">登陆</button> </div> </div> </form> </div> <script src="/js/jquery-2.2.1.min.js"></script> <script src="/js/bootstrap.min.js"></script> </body> </html>复制代码
二、写一个LoginController
package com.zb.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class LoginController {
@RequestMapping("/login")
public String login(){
return "login";
}
}复制代码
三、加依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>复制代码
四、
重启， http://localhost:8080/login 则会看到登陆页面github
4、集成mybatis
一、
springboot的配置文件分为两种：application.properties和application.yml 咱们把它改为application.yml这种更直观web
spring: application: name: myspringboot output: ansi: enabled: always profiles: active: dev thymeleaf: encoding: UTF-8 prefix: classpath:/templates/ server: tomcat: uri-encoding: UTF-8 max-connections: 500 min-spare-threads: 25 max-threads: 300 accept-count: 200 port: 8080 mybatis: type-aliases-package: com.zb.mapper mapper-locations: classpath:mapping/*.xml pagehelper: helper-dialect: mysql reasonable: true support-methods-arguments: true params: count=countSql logging: level: com.zb.mapper: debug --- #开发配置 spring: profiles: dev datasource: url: jdbc:mysql://localhost:3306/zb_db?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false&useSSL=false username: root password: 123456 driver-class-name: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20复制代码
二、添加依赖
<dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>RELEASE</version> </dependency> <!-- 分页插件 --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.2.3</version> </dependency>复制代码
三、建表
CREATE datebase zb_db;复制代码
CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(255) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, `mobile` varchar(255) DEFAULT NULL, `email` varchar(255) DEFAULT NULL, `sex` varchar(255) DEFAULT NULL, `nickname` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;复制代码
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(1, 'admin', '123456', '13918891675','mmc@163.com', '男', '管理员'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(2, 'lisi2', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(3, 'lisi3', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(4, 'lisi4', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(5, 'lisi5', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(6, 'lisi6', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(7, 'lisi7', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(8, 'lisi8', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(9, 'lisi9', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(10, 'lisi10', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(11, 'lisi11', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(12, 'lisi12', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(13, 'lisi13', '123456', '13918891675','mmc@163.com', 'm', 'lisi1'); insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(14, 'lisi14', '123456', '13918891675','mmc@163.com', 'm', 'lisi1');复制代码
四、用mybatisgenerator自动生成文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!-- 数据库驱动:选择你的本地硬盘上面的数据库驱动包--> <classPathEntry location="C:\Users\DELL\Downloads\mysql-connector-java-5.1.22-bin.jar"/> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <!-- 是否去除自动生成的注释 true：是 ： false:否 --> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--数据库连接URL，用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/zb_db" userId="root" password="123456"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!-- 生成模型的包名和位置--> <javaModelGenerator targetPackage="com.zb.model" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- 生成映射文件的包名和位置--> <sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!-- 生成DAO的包名和位置--> <javaClientGenerator type="XMLMAPPER" targetPackage="com.zb.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名--> <table tableName="role_permission" domainObjectName="RolePermission" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>复制代码
五、在pom里面添加plugin
<!-- mybatis generator 自动生成代码插件 -->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
</plugin>复制代码
六、用mvn mybatis-generator:generate -e命令生成文件
此时目录结构ajax
七、写dao和service,controller,mapper
mapper增长了几个方法
@Select("Select * from user")
List<User> selectAll();
@Select("Select * from user where username = #{username} and password = #{password}")
User selectByUsernamePass(@Param("username") String username, @Param("password") String password);
@Select("Select * from user where username = #{username}")
User selectByUsername(@Param("username") String username);复制代码
dao和service都是正常调用，下面是controller
package com.zb.controller;
import com.github.pagehelper.PageInfo;
import com.zb.model.User;
import com.zb.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/user")
@ResponseBody
public User getUserById(int id){
User user = userService.selectByPrimaryKey(id);
return user;
}
@RequestMapping("/userlist")
public String getUserList(Model model, PageInfo pageInfo){
int pageNum = (pageInfo.getPageNum() == 0)? 1 : pageInfo.getPageNum();
int pageSize = (pageInfo.getPageSize() == 0)? 10 : pageInfo.getPageSize();
PageInfo<User> result = userService.selectAll(pageNum, pageSize);
model.addAttribute("users", result.getList());
model.addAttribute("pageInfo", result);
return "userlist";
}
@RequestMapping("/userdelete")
public String userdelete(int id){
userService.deleteByPrimaryKey(id);
return "redirect:/userlist";
}
@RequestMapping("/useredit")
public String useredit(int id, Model model){
User user = userService.selectByPrimaryKey(id);
model.addAttribute("user", user);
return "useredit";
}
@RequestMapping(value = "/userupdateoradd", method = RequestMethod.POST)
public String userUpdateOrAdd(User user){
if(user.getId() == 0){
userService.insertSelective(user);
} else {
userService.updateByPrimaryKeySelective(user);
}
return "redirect:/userlist";
}
}复制代码
页面userlist.html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8" />
<title>用户管理</title>
<link href="/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">
<div>
<nav class="navbar navbar-default" role="navigation">
<div class="container-fluid">
<div>
<ul class="nav navbar-nav" >
<li><a href="/userlist">用户管理</a></li>
<li><a href="#">书籍管理</a></li>
</ul>
</div>
</div>
</nav>
</div>
<div>
<h2>用户管理</h2>
<table width="100%" border="0" cellpadding="0" cellspacing="0" class="table_list">
<thead>
<tr>
<th width="20%">编号</th>
<th width="20%">用户名</th>
<th width="20%">电子邮箱</th>
<th width="20%">手机</th>
<th width="20%">操做</th>
</tr>
</thead>
<tbody>
<tr th:each="user:${users}">
<td height="40px"><a th:text="${user.id}" data-toggle="modal" data-target="#myModal" onclick="values(this)"></a></td>
<td th:text="${user.username}"></td>
<td th:text="${user.email}"></td>
<td th:text="${user.mobile}"></td>
<td><a href="#" class="delete_a" th:value="${user.id}">删除</a></td>
</tr>
</tbody>
</table>
</div>
</div>
<script src="/js/jquery-2.2.1.min.js"></script>
<script src="/js/bootstrap.min.js"></script>
</body>
</html>复制代码
8，在ZbookApplication上加上注解扫描
@ComponentScan(basePackages = {"com.zb"})
@MapperScan("com.zb.mapper")复制代码
九、顺便把分页加上（依赖包以前已经加了）
service层
@Override
public PageInfo<User> selectAll(int pageNum, int pageSize) {
PageHelper.startPage(pageNum, pageSize);
List<User> users = userDao.selectAll();
PageInfo<User> pageInfo = new PageInfo<>(users);
return pageInfo;
}复制代码
controller层
public String getUserList(Model model, PageInfo pageInfo){
int pageNum = (pageInfo.getPageNum() == 0)? 1 : pageInfo.getPageNum();
int pageSize = (pageInfo.getPageSize() == 0)? 10 : pageInfo.getPageSize();
PageInfo<User> result = userService.selectAll(pageNum, pageSize);
model.addAttribute("users", result.getList());
model.addAttribute("pageInfo", result);
return "userlist";
}复制代码
页面修改：
<div id="example" style="text-align: center"> <ul id="pageLimit"></ul> </div>
<input type="hidden" id="pageNum" name="pageNum" th:value="${pageInfo.pageNum}" />
<input type="hidden" id="pages" name="pages" th:value="${pageInfo.pages}" />复制代码
<script src="/js/bootstrap-paginator.min.js"></script>
<script>
$('#pageLimit').bootstrapPaginator({
currentPage: $("#pageNum").val(),
totalPages: $("#pages").val(),
size: "normal",
bootstrapMajorVersion: 3,
alignment: "right",
numberOfPages: 5,
itemTexts: function (type, page, current) {
switch (type) {
case "first": return "首页";
case "prev": return "上一页";
case "next": return "下一页";
case "last": return "末页";
case "page": return page;
}
},
onPageClicked: function (event, originalEvent, type, page){//给每一个页眉绑定一个事件，其实就是ajax请求，其中page变量为当前点击的页上的数字。
window.location.href = "userlist?pageNum=" + page;
}
});
$(function(){
$(".delete_a").click(function(){
var userId=$(this).attr("value");
if(confirm("确认删除吗？")){
window.location.href="/userdelete?id=" + userId;
return ;
}
});
});
</script>复制代码
此时目录
此时重启，输入 http://localhost:8080/userlist 就会看到user列表，也能够分页。
5、简单登陆，用filter实现
一、
package com.zb.filter;
import com.zb.model.User;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
@WebFilter(filterName = "sessionFilter",urlPatterns = {"/*"})
public class SessionFilter implements Filter {
String NO_LOGIN = "您还未登陆";
String[] includeUrls = new String[]{"/login","/login_in"};
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest)servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
HttpSession session = request.getSession();
String url = request.getRequestURI();
boolean needFilter = isNeedFilter(url);
//静态资源放行
if(url.endsWith(".css")||url.endsWith(".js")||url.endsWith(".jpg")
||url.endsWith(".gif")||url.endsWith(".png")){
filterChain.doFilter(servletRequest, servletResponse);
return;
}
if(!needFilter){
filterChain.doFilter(servletRequest, servletResponse);
} else {
User user = (User)session.getAttribute(session.getId());
if(user != null){
filterChain.doFilter(servletRequest, servletResponse);
} else {
String requestType = request.getHeader("X-Requested-With");
//判断是不是ajax请求
if(requestType!=null && "XMLHttpRequest".equals(requestType)){
response.getWriter().write(this.NO_LOGIN);
}else{
//重定向到登陆页(须要在static文件夹下创建此html文件)
response.sendRedirect(request.getContextPath()+"/login");
}
return;
}
}
}
public boolean isNeedFilter(String uri) {
for (String includeUrl : includeUrls) {
if(includeUrl.equals(uri)) {
return false;
}
}
return true;
}
@Override
public void destroy() {
}
}复制代码
二、在ZbookApplication上加注解
@ServletComponentScan复制代码
三、在LoginController下写登陆逻辑
package com.zb.controller;
import com.zb.model.User;
import com.zb.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
@Controller
public class LoginController {
@Autowired
private UserService userService;
@RequestMapping("/login")
public String login(){
return "login";
}
@RequestMapping(value = "/login_in", method = RequestMethod.POST)
public String login_in(User user, HttpServletRequest request, Model model){
User user1 = userService.validateUser(user.getUsername(), user.getPassword());
if(user1 == null){
return "login";
}
HttpSession session = request.getSession();
session.setAttribute(session.getId(), user1);
return "redirect:/userlist";
}
@RequestMapping("/logout")
public String logout(HttpServletRequest request){
request.getSession().removeAttribute(request.getSession().getId());
return "login";
}
}复制代码
如今就能够简单的登陆了
四、修改页面让页面显示用户名和退出
<div>
<a href="logout" style="display: inline-block; float: right">退出</a>
<p th:text="${#httpSession.getAttribute(#httpSession.getId()).username}" style="display: inline-block; float: right"></p>
<p style="display: inline-block; float: right">您好，</p>
</div>复制代码
6、权限
权限管理咱们使用如今比较流行的shiro,原理就不说了，直接说怎么使用
一、加依赖包
<!--shiro权限--> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>com.github.theborakompanioni</groupId> <artifactId>thymeleaf-extras-shiro</artifactId> <version>2.0.0</version> </dependency>复制代码
二、建表
shiro须要5张表：用户、角色、权限、用户角色关联表，角色权限关联表 用户表已创建，如今续建4张表
CREATE TABLE `role` ( `id` int(11) NOT NULL AUTO_INCREMENT, `rolename` varchar(255) DEFAULT NULL, `description` varchar(255) DEFAULT NULL, `status` varchar(255) DEFAULT NULL, `create_time` DATE DEFAULT NULL, `update_time` DATE DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; CREATE TABLE `permission` ( `id` int(11) NOT NULL AUTO_INCREMENT, `permissionname` varchar(255) DEFAULT NULL, `resourceType` varchar(255) DEFAULT NULL, `url` varchar(255) DEFAULT NULL, `permission` varchar(255) DEFAULT NULL, `status` varchar(255) DEFAULT NULL, `create_time` DATE DEFAULT NULL, `update_time` DATE DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; CREATE TABLE `user_role` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` varchar(255) DEFAULT NULL, `role_id` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; CREATE TABLE `role_permission` ( `id` int(11) NOT NULL AUTO_INCREMENT, `role_id` varchar(255) DEFAULT NULL, `permission_id` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;复制代码
insert into `role`(id, rolename, description, status, create_time, update_time) VALUES (1, 'admin', '管理员', 'use', '2018-08-10', '2018-08-10'); insert into `role`(id, rolename, description, status, create_time, update_time) VALUES (2, 'manage', '经理', 'use', '2018-08-10', '2018-08-10'); insert into `role`(id, rolename, description, status, create_time, update_time) VALUES (3, 'user', '普通用户', 'use', '2018-08-10', '2018-08-10'); INSERT INTO `permission` (id, permissionname, resourceType, url, permission, status, create_time, update_time) VALUES (1,'用户管理','menu', 'userlist','user:list','use','2018-08-10', '2018-08-10'); INSERT INTO `permission` (id, permissionname, resourceType, url, permission, status, create_time, update_time) VALUES (2,'用户修改','menu', 'useredit','user:edit','use','2018-08-10', '2018-08-10'); INSERT INTO `permission` (id, permissionname, resourceType, url, permission, status, create_time, update_time) VALUES (3,'用户删除','menu', 'userdelete','user:delete','use','2018-08-10', '2018-08-10'); INSERT INTO `user_role` (id, user_id, role_id) VALUES (1, 1 ,1); INSERT INTO `user_role` (id, user_id, role_id) VALUES (2, 1 ,2); INSERT INTO `user_role` (id, user_id, role_id) VALUES (3, 1 ,3); INSERT INTO `user_role` (id, user_id, role_id) VALUES (4, 2 ,2); INSERT INTO `user_role` (id, user_id, role_id) VALUES (5, 3 ,3); INSERT INTO `user_role` (id, user_id, role_id) VALUES (6, 4 ,3); INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (1, 1, 1); INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (2, 1, 2); INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (3, 1, 3); INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (4, 2, 1); INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (5, 2, 2); INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (6, 3, 1);复制代码
三、加载bean
package com.zb.shiro;
import java.util.LinkedHashMap;
import java.util.Map;
import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.mgt.SecurityManager;

*
Apache Shiro 核心经过 Filter 来实现，就好像SpringMvc 经过DispachServlet 来主控制同样。
既然是使用 Filter 通常也就能猜到，是经过URL规则来进行过滤和权限校验，因此咱们须要定义一系列关于URL的规则和访问权限。
*/
@Configuration
public class ShiroConfiguration {
private static final Logger logger = LoggerFactory.getLogger(ShiroConfiguration.class);

proxy.setTargetBeanName("shiroFilter");
filterRegistrationBean.setFilter(proxy);
return filterRegistrationBean;
}
/**

Filter Chain定义说明
一、一个URL能够配置多个Filter，使用逗号分隔
二、当设置多个过滤器时，所有验证经过，才视为经过
三、部分过滤器可指定参数，如perms，roles

四、写Realm
package com.zb.shiro;
import com.zb.model.Permission;
import com.zb.model.Role;
import com.zb.model.User;
import com.zb.service.UserService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import javax.annotation.Resource;
/**
* 身份校验核心类;
*
* @version v.0.1
*/
public class MyShiroRealm extends AuthorizingRealm{
private static final Logger logger = LoggerFactory.getLogger(MyShiroRealm.class);
private static String SALT = "mySlalt";
@Resource
private UserService userService;
/**
* 认证信息.(身份验证)
* :
* Authentication 是用来验证用户身份
* @param token
* @return
* @throws AuthenticationException
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
logger.info("MyShiroRealm.doGetAuthenticationInfo()");
//获取用户的输入的帐号.
String username = (String)token.getPrincipal();
//经过username从数据库中查找 User对象，若是找到，没找到.
//实际项目中，这里能够根据实际状况作缓存，若是不作，Shiro本身也是有时间间隔机制，2分钟内不会重复执行该方法
User user = userService.selectByUsername(username);
logger.info("----->>userInfo=" + user.toString());
if(user == null){
return null;
}
/*
* 获取权限信息:这里没有进行实现，
* 请自行根据UserInfo,Role,Permission进行实现；
* 获取以后能够在前端for循环显示全部连接;
*/
//userInfo.setPermissions(userService.findPermissions(user));
userService.findRoleAndPermissions(user);
//帐号判断;
//加密方式;
//交给AuthenticatingRealm使用CredentialsMatcher进行密码匹配，若是以为人家的很差能够自定义实现
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
user, //用户名
user.getPassword(), //密码
ByteSource.Util.bytes(user.getUsername() + SALT),//salt=username+salt
getName() //realm name
);
//明文: 若存在，将此用户存放到登陆认证info中，无需本身作密码对比，Shiro会为咱们进行密码对比校验
// SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
// userInfo, //用户名
// userInfo.getPassword(), //密码
// getName() //realm name
// );
return authenticationInfo;
}
/**
* 此方法调用 hasRole,hasPermission的时候才会进行回调.
*
* 权限信息.(受权):
* 一、若是用户正常退出，缓存自动清空；
* 二、若是用户非正常退出，缓存自动清空；
* 三、若是咱们修改了用户的权限，而用户不退出系统，修改的权限没法当即生效。
* （须要手动编程进行实现；放在service进行调用）
* 在权限修改后调用realm中的方法，realm已经由spring管理，因此从spring中获取realm实例，
* 调用clearCached方法；
* :Authorization 是受权访问控制，用于对用户进行的操做受权，证实该用户是否容许进行当前操做，如访问某个连接，某个资源文件等。
* @param principals
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
logger.info("权限配置-->MyShiroRealm.doGetAuthorizationInfo()");
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
User userInfo = (User)principals.getPrimaryPrincipal();
///在认证成功以后返回.
//设置角色信息.
//支持 Set集合,
//用户的角色对应的全部权限
for(Role role:userInfo.getRoleList()){
authorizationInfo.addRole(role.getRolename());
for(Permission p:role.getPermissionList()){
authorizationInfo.addStringPermission(p.getPermission());
}
}
return authorizationInfo;
}
}复制代码
五、自动生成那四个表的代码，加相关的
@Select("select * from Role where id in (select role_id from user_role where user_id = #{userId})")
List<Role> selectRoleByUserId(@Param("userId") int userId);复制代码
@Select("select * from permission where id in (select permission_id from role_permission where role_id = #{roleId})")
List<Permission> selectPermissionIdByRoleId(@Param("roleId") int roleId);复制代码
六、修改LoginController
修改登陆方法
@RequestMapping(value = "/login_in", method = RequestMethod.POST)
public String login_in(User user, HttpServletRequest request, Model model){
User user1 = userService.validateUser(user.getUsername(), user.getPassword());
if(user1 == null){
return "login";
}
// (1) session
// HttpSession session = request.getSession();
// session.setAttribute(session.getId(), user1);
// return "redirect:/userlist";
// (3) shiro
String msg ;
UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
token.setRememberMe(true);
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
if (subject.isAuthenticated()) {
//shiro 的session和request的session封装的是一个，就是说两个均可以
// request.getSession().setAttribute(request.getSession().getId(),user);
subject.getSession().setAttribute(subject.getSession().getId(),user);
return "redirect:/userlist";
} else {
return "login";
}
} catch (IncorrectCredentialsException e) {
msg = "登陆密码错误. Password for account " + token.getPrincipal() + " was incorrect.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExcessiveAttemptsException e) {
msg = "登陆失败次数过多";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (LockedAccountException e) {
msg = "账号已被锁定. The account for username " + token.getPrincipal() + " was locked.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (DisabledAccountException e) {
msg = "账号已被禁用. The account for username " + token.getPrincipal() + " was disabled.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExpiredCredentialsException e) {
msg = "账号已过时. the account for username " + token.getPrincipal() + " was expired.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnknownAccountException e) {
msg = "账号不存在. There is no user with username of " + token.getPrincipal();
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnauthorizedException e) {
msg = "您没有获得相应的受权！" + e.getMessage();
model.addAttribute("message", msg);
System.out.println(msg);
}
return "login";
}
@RequestMapping("/logout")
public String logout(HttpServletRequest request){
// request.getSession().removeAttribute(request.getSession().getId());
SecurityUtils.getSubject().getSession().removeAttribute(SecurityUtils.getSubject().getSession().getId());
return "login";
}复制代码
七、修改contorller方法，或者在页面里面加权限
@RequestMapping("/userlist")
@RequiresPermissions("user:list")复制代码
@RequestMapping("/userdelete")
@RequiresPermissions("user:delete")复制代码
这种或者 页面上
<shiro:hasPermission name="user:delete"></shiro:hasPermission>复制代码
至此，权限就加好了
