SSM整合
SSM整合
整合说明：SSM整合能够使用多种方式，我们会选择XML（第三方对象） + 注解（本身new的对象）的方式css
整合的思路html
（1）：先搭建整合的环境前端
（2）：先把Spring的配置搭建完成java
（3）：再使用Spring整合SpringMVC框架mysql
（4）：最后使用Spring整合MyBatis框架jquery
数据源:web
create database itcastspringmvc;use itcastspringmvc;create table account( id int primary key auto_increment, name varchar(20), money double);

建立包com.le.ssm.domain,建立类Account.javaspring
public class Account implements Serializable {private Integer id;private String name;private Double money;}
DAOsql
建立包com.le.ssm.dao，建立类AccountDao.java数据库
/*** AccountMapper接口，不用编写实现类，框架生成代理对象*/public interface AccountDao {public List<Account> findAll();public void saveAccount(Account account);}
Service
建立包com.le.ssm.service，建立接口AccountService.java
public interface AccountService {public List<Account> findAll();public void saveAccount(Account account);}
建立类AccountServiceImpl，实现接口
/*** 帐号的实现类*/public class AccountServiceImpl implements AccountService {private AccountDao accountDao;public List<Account> findAll() {System.out.println("业务层：查询全部的账户...");return accountDao.findAll();}public void saveAccount(Account account) {System.out.println("业务层：保存账户..."); accountDao.saveAccount(account);}}
建立包com.le.ssm.controller，建立类AccountController.java
/*** 账户*/public class AccountController {private AccountService accountService;/** * 查询全部 * @return */public String findAll() {System.out.println("表现层：查询全部帐户...");List<Account> list = accountService.findAll();for (Account account : list) {System.out.println(account);}return "success";}/** * 保存 * @return */public String saveAccount(Account account) {System.out.println("表现层：保存帐户..."); accountService.saveAccount(account);return "success";}}
Spring的环境
在项目中的resources文件夹下建立applicationContext.xml的配置文件，编写具体的配置信息。
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"><!-- 开启注解扫描 -->当只使用SpringMVC的注解管理所有的时候,这里就不须要开启注解了<!--<context:component-scan base-package="com.le.ssm"> <!-- 忽略某些注解，把Controller给忽略了 --><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan>--></beans>
AccountService.java
/*** 帐号的实现类*/@Service("accountService")public class AccountServiceImpl implements AccountService {}
在项目中编写测试方法，进行测试
建立测试类：com.le.test.TestService.java
public class TestService {/** * 测试Service层 */@Testpublic void testService(){ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");AccountService as = (AccountService) ac.getBean("accountService"); as.findAll();}}
SpringMVC框架
web.xml
在web.xml中配置DispatcherServlet前端控制器
<!-- 配置前端控制器：服务器启动必须加载，须要加载springmvc.xml配置文件 --><servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 配置初始化参数，建立完DispatcherServlet对象，加载springmvc.xml配置文件 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><!-- 服务器启动的时候，让DispatcherServlet对象建立 --><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!-- 在web.xml中配置CharacterEncodingFilter过滤器解决post请求中文乱码 配置解决中文乱码的过滤器 --><filter><filter-name>characterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>characterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>
springmvc.xml
在resources下，建立springmvc.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><!-- 扫描controller的注解，别的不扫描 --><context:component-scan base-package="com.le.ssm"><!--<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> 排除Service注解的扫描，让spring扫描，不然事务可能会失效 <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"></context:exclude-filter> --></context:component-scan><!-- 当使用下面这一句整合了APP的注解后,就不须要配上面两句了 --><import resource="applicationContext.xml"></import><!-- 配置视图解析器 --><bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- JSP文件所在的目录 --><property name="prefix" value="/WEB-INF/pages/" /><!-- 文件的后缀名 --><property name="suffix" value=".jsp" /></bean><!-- 设置静态资源不过滤，能够使用：--><mvc:default-servlet-handler></mvc:default-servlet-handler><!-- <mvc:resources location="/css/" mapping="/css/**" /> <mvc:resources location="/images/" mapping="/images/**" /> <mvc:resources location="/js/" mapping="/js/**" />--><!-- 开启对SpringMVC注解的支持 --><mvc:annotation-driven /></beans>
其中：
表示springmvc的注解包含@Controller的注解。
为何要包含@Controller注解呢？
1）SpringMVC IOC容器 存在Controller的实例对象
2）Spring IOC容器 存在Controller的实例和Service层实例以及Dao层实例
重叠会引起一些问题：
例如：事务失效、相关注解失效
解决方案一：
SpringMVC只扫描 @Controller 注解、不扫描@Service注解
Spring不扫描 @Controller 注解
解决方案二：（建议使用）
只让SpringMVC扫描，不让Spring扫描
在springMVC的配置中添加
AccountController.java
/*** 账户*/@Controller@RequestMapping(path = "account")public class AccountController {@Autowiredprivate AccountService accountService;/** * 查询全部 * @return */@RequestMapping(path = "/findAll")public String findAll() {System.out.println("表现层：查询全部帐户...");return "success";}}
index.jsp
<body><h3>帐号操做</h3><a href="account/findAll">查询全部帐号</a></body>
success.jsp（WEB-INF/pages/success.jsp）
<body><h1>访问成功</h1></body>
Spring整合SpringMVC框架
目的：在controller中能成功的调用service对象中的方法。（由spring建立对象，注入到Action中使用）
在项目启动的时候，就去加载applicationContext.xml的配置文件，在web.xml中配置ContextLoaderListener监听器（默认该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文件）。使用contextConfigLocation的属性让它加载类路径下的applicationContext.xml。
web.xml
<!-- 配置Spring的监听器，默认加载WEB-INF下的applicationContext.xml --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 该监听器默认只加载WEB-INF下的applicationContext.xml配置文件，经过contextConfigLocation改变位置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param>
AccountController.java
@Controller@RequestMapping(path = "account")public class AccountController {@Autowiredprivate AccountService accountService;/** * 查询全部 * @return */@RequestMapping(path = "/findAll")public String findAll() {System.out.println("表现层：查询全部帐户...");List<Account> list = accountService.findAll();System.out.println(list);return "success";}}
Mybatis框架
SqlMapConfig.xml
在web项目中编写SqlMapConfig.xml的配置文件，放置到resources下，编写核心配置文件
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><environments default="mysql"><environment id="mysql"><transactionManager type="JDBC"/><dataSource type="POOLED"><property name="driver" value="com.mysql.jdbc.Driver"/><property name="url" value="jdbc:mysql:///itcastspringmvc"/><property name="username" value="root"/><property name="password" value="root"/></dataSource></environment></environments><!-- 使用的是注解 --><mappers><!-- <mapper class="com.le.ssm.dao.AccountDao"/> --><!-- 该包下全部的dao接口均可以使用 --><package name="com.le.ssm.dao"/></mappers></configuration>
Xml的回顾：咱们采用的是注解
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.le.ssm.dao.AccountDao"><!--查询全部--><select id="findAll" resultType="com.le.ssm.domain.Account"> select * from account</select><!--保存--><insert id="save" parameterType="com.le.ssm.domain.Account"> insert into account(name,money) values (#{name},#{money})</insert></mapper>
AccountDao.java
在AccountDao接口的方法上添加注解，编写SQL语句
/*** AccountDao接口，不用编写实现类，框架生成代理对象*/public interface AccountDao {@Select(value = "select * from account")public List<Account> findAll();@Insert(value = "insert into account (name,money) values (#{name},#{money})")public void saveAccount(Account account);}
在测试环境下，com.le.test中，编写测试方法
public class TestMybatis {@Testpublic void testFindAll() throws Exception {// 加载配置文件InputStream in = Resources.getResourceAsStream("sqlMapConfig.xml");// 建立工厂SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(in);// 建立sqlSession对象SqlSession sqlSession = sessionFactory.openSession();// 获取代理对象AccountDao accountDao = sqlSession.getMapper(AccountDao.class);// 获取查询全部的方法List<Account> list = accountDao.findAll();for(Account account:list){System.out.println(account);}// 释放资源 sqlSession.close(); in.close();}@Testpublic void testSave() throws Exception {Account account = new Account(); account.setName("小菲"); account.setMoney(400d);// 加载配置文件InputStream in = Resources.getResourceAsStream("sqlMapConfig.xml");// 建立工厂SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(in);// 建立sqlSession对象SqlSession sqlSession = sessionFactory.openSession();// 获取代理对象AccountDao accountDao = sqlSession.getMapper(AccountDao.class); accountDao.saveAccount(account);// 提交事务 sqlSession.commit();// 释放资源 sqlSession.close(); in.close();}}
Spring整合MyBatis框架
applicationContext.xml
目的：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中
<!-- 配置C3P0的链接池对象 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="com.mysql.jdbc.Driver"></property><property name="jdbcUrl" value="jdbc:mysql:///itcastspringmvc" /><property name="user" value="root" /><property name="password" value="root" /></bean><!-- 配置SqlSession的工厂 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /></bean><!-- 配置扫描dao的包 --><bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.le.ssm.dao"/></bean>
SqlMapConfig.xml配置文件能够删除。
AccountDao.java
在AccountDao接口中添加@Repository注解，也能够不填加。
@Repositorypublic interface AccountDao {@Select(value = "select * from account")public List<Account> findAll();@Insert(value = "insert into account (name,money) values (#{name},#{money})")public void saveAccount(Account account);}
TestSpringMybatis
@Testpublic void testFindAllSpring() throws Exception {ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");AccountDao accountDao = ac.getBean(AccountDao.class);List<Account> list = accountDao.findAll();for(Account account:list){System.out.println(account);}}
AccountServiceImpl.java
在service中注入dao对象
/*** 帐号的实现类*/@Service("accountService")public class AccountServiceImpl implements AccountService {@Autowiredprivate AccountDao accountDao;public List<Account> findAll() {System.out.println("业务层：查询全部的账户...");return accountDao.findAll();}public void saveAccount(Account account) { accountDao.saveAccount(account);}}
AccountController.java
@Controller@RequestMapping(path = "account")public class AccountController {@Autowiredprivate AccountService accountService;/** * 查询全部 * @return */@RequestMapping(path = "/findAll")public String findAll(Model model) {System.out.println("表现层：查询全部帐户...");List<Account> list = accountService.findAll();System.out.println(list); model.addAttribute("list",list);return "success";}/** * 保存 * @return */@RequestMapping(path = "/save")public String saveAccount(Account account) { accountService.saveAccount(account);return "success";}}
success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %><html><head><title>Title</title></head><body><h1>访问成功</h1><c:forEach items="${list}" var="account"> ${account.id}--- ${account.name}--- ${account.money}<br></c:forEach></body></html>
配置Spring的声明式事务管理
applicationContext.xml
<!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean><!-- 配置事务通知 --><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="*" read-only="true"/><tx:method name="save*" isolation="DEFAULT" propagation="REQUIRED" read-only="false"/><tx:method name="update*" isolation="DEFAULT" propagation="REQUIRED" read-only="false"/><tx:method name="delete*" isolation="DEFAULT" propagation="REQUIRED" read-only="false"/></tx:attributes></tx:advice><!-- 配置AOP加强事务 --><aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* com.le.ssm.service..*.*(..))"/></aop:config>
Spring的声明式事务处理（注解方式）
<!--使用注解的方式，配置spring的声明式事务处理--><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"></property></bean><!--开启注解的方式使用事务--><tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
在Service的类上，配置@Transactional
@Service@Transactionalpublic class AccountServiceImpl implements AccountService {
index.jsp
<hr><form action="account/save" method="post"> 姓名：<input type="text" name="name"/><br/> 金额：<input type="text" name="money"/><br/><input type="submit" value="保存"/><br/></form>
AccountController.java
/*** 保存* @return*/@RequestMapping(path = "/save")public void saveAccount(Account account, HttpServletRequest request, HttpServletResponse response) throws Exception {System.out.println("表现层：保存帐户..."); accountService.saveAccount(account); response.sendRedirect(request.getContextPath()+"/account/findAll");return;}
建议使用redirect关键字
@RequestMapping(path = "/save")public String saveAccount(Account account) throws Exception {System.out.println("表现层：保存帐户..."); accountService.saveAccount(account);return "redirect:/account/findAll";}
让SpringMVC扫描，不让Spring扫描

实体类User
public class User implements Serializable {private String number;private String name;private String password;private String mobile;private String qq;private String email;}
拷贝页面到项目
建立UserController.java
页面数据发送到Controller，建立Controller
@Controller@RequestMapping(value = "/user")public class UserController {@Autowiredprivate UserService userService;/*** * 增长用户 * @param user * @return */@RequestMapping(value = "/save")public String save(User user){//增长int acount = userService.saveUser(user);if(acount>0){//新增成功，返回登陆页面return "redirect:/login.html";}else{//新增失败，返回注册页面return "redirect:/register.html";}}}
建立接口UserService.java和实现类UserServiceImpl.java
public interface UserService {/*** * 增长用户 * @param user * @return */int saveUser(User user);}
@Servicepublic class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;public int saveUser(User user) {return userDao.save(user);}}
若是是注解的方式配置声明式事务处理，须要添加在UserServiceImpl的类上添加：@Transactional
建立接口UserDao.java
//@Repositorypublic interface UserDao {/*** * 增长操做 * @param user * @return */@Insert("insert into user(number,password,mobile)values(#{number},#{password},#{mobile})")int save(User user);}
修改页面
<form id="subform" action="/user/save" method="post" class="sui-form form-horizontal"><div class="control-group"><label class="control-label">用户名：</label><div class="controls"><input type="text" name="number" placeholder="请输入你的用户名" class="input-xfat input-xlarge"></div></div><div class="control-group"><label for="inputPassword" class="control-label">登陆密码：</label><div class="controls"><input type="password" id="pwd" name="password" placeholder="设置登陆密码" class="input-xfat input-xlarge"></div></div><div class="control-group"><label for="inputPassword" class="control-label">确认密码：</label><div class="controls"><input type="password" id="rpwd" placeholder="再次确认密码" class="input-xfat input-xlarge"></div></div><div class="control-group"><label class="control-label">手机号：</label><div class="controls"><input type="text" name="mobile" placeholder="请输入你的手机号" class="input-xfat input-xlarge"></div></div><div class="control-group"><label for="inputPassword" class="control-label"> </label><div class="controls"><input name="m1" type="checkbox" value="2" checked=""><span>赞成协议并注册《品优购用户协议》</span></div></div><div class="control-group"><label class="control-label"></label><div class="controls btn-reg"><button class="sui-btn btn-block btn-xlarge btn-danger" type="button" id="btn">完成注册</button></div></div></form>
<script src="plugins/jQuery/jquery-2.2.3.min.js"></script><script> $(function () {/* * 点击注册按钮 * 判断2次密码是否一致 * 若是一致，提交到后台，不然提示错误 * */ $('#btn').click(function () {//获取2次密码var pwd = $('#pwd').val();var rpwd=$('#rpwd').val();if(pwd==rpwd){//提交到后台 $('#subform').submit();}else{//提示 alert("2次密码输入有误")}});});</script>
用户登陆
login.html登陆页面
<form class="sui-form" action="/user/login" method="post"><div class="input-prepend"><span class="add-on loginname"></span><input id="prependedInput" type="text" name="number" placeholder="邮箱/用户名/手机号" class="span2 input-xfat"></div><div class="input-prepend"><span class="add-on loginpwd"></span><input id="prependedInput" type="password" name="password" placeholder="请输入密码" class="span2 input-xfat"></div><div class="setting"><label class="checkbox inline"><input name="m1" type="checkbox" value="2" checked="">自动登陆</label><span class="forget">忘记密码？</span></div><div class="logined"><button class="sui-btn btn-block btn-xlarge btn-danger" type="submit">登 录</button></div></form>
UserController.java
/**** 用户登陆* @return*/@RequestMapping(value = "/login")public String login(User user, HttpSession session){//数据库查询登陆User loginUser = userService.findByNumberAndPassword(user);//判断loginUser是否为空if(loginUser!=null){//登陆成功跳转到欢迎页 session.setAttribute("loginUser",user);return "redirect:/index/welcome";}else{//为空，登陆失败，继续登陆return "redirect:/login.html";}}
UserServiceImpl.java
public User findByNumberAndPassword(User user) {return userDao.findByNumberAndPassword(user);}
UserDao.java
/***** 登陆* @param user* @return*/@Select("select * from user where number=#{number} and password=#{password}")User findByNumberAndPassword(User user);//@Select(value = "select * from user where number = #{number} and password=#{password}")//User findByNumberAndPassword(@Param("number") String number, @Param("password") String password);
登陆成功--->重定向到欢迎页WelcomeController.java
@Controller@RequestMapping(value = "/index")public class WelcomeController {/*** * 欢迎页 * @return */@RequestMapping(value = "/welcome")public String welcome(){return "index";}}
将admin下的index.html拷贝到WEB-INF\pages下
同时建立index.jsp，将index.html的内容放置到index.jsp
在index.jsp中获取登陆信息
<!-- Sidebar toggle button--><a href="#" class="sidebar-toggle" data-toggle="offcanvas" role="button"><span class="sr-only">Toggle navigation</span></a>欢迎你：${sessionScope.loginUser.number}
整合拦截器
【需求】：用户若是已经登陆
用户若是没有登陆，则不能访问欢迎页
LoginInterceptor.java
声明拦截器
建立包com.le.ssm.interceptor
建立类LoginInterceptor.java
public class LoginInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {/**** * 用户是否在线 * 若是不在线，不容许访问欢迎页 */Object loginUser = request.getSession().getAttribute("loginUser");if(loginUser==null){ response.sendRedirect(request.getContextPath()+"/login.html");return false;}return true;}}
springmvc.xml
<!--配置拦截器--><mvc:interceptors><mvc:interceptor><!--拦截 的url，全部拦截--><mvc:mapping path="/**"/><!--排除--><mvc:exclude-mapping path="/*.html"></mvc:exclude-mapping><mvc:exclude-mapping path="/js/**"></mvc:exclude-mapping><mvc:exclude-mapping path="/css/**"></mvc:exclude-mapping><mvc:exclude-mapping path="/img/**"></mvc:exclude-mapping><mvc:exclude-mapping path="/plugins/**"></mvc:exclude-mapping><mvc:exclude-mapping path="/user/save"></mvc:exclude-mapping><mvc:exclude-mapping path="/user/login"></mvc:exclude-mapping><bean class="com.le.ssm.interceptor.SessionInterceptor"></bean></mvc:interceptor></mvc:interceptors>
【测试】从新启动，在没有Session的状况下，访问/index/welcome，此时重定向到登陆页面。
