spring+springmvc+hibernate 礼品管理系统

spring+springmvc+hibernate template礼品管理系统

1.简单介绍

    如标题所示，这篇文章简单写了一个基于spring+springmvc+hibernate template的礼品管理系统，适合初学者，这是个人第三篇文章，但愿能够经过这篇文章让同窗了解这个系统基本流程，虽然逐渐退出主流，可是还有不少地方思路值得咱们学习。若有兴趣，能够随时联系我：1763907618.

2.环境搭建

    个人项目测试成功，前台jsp,没有美化，主要是后台功能都能实现。

    jdk：1.6；

    数据库：mysql5.6；

    基于hibernate的jar包，cglib.jar可能还会有冲突，每次发布项目须要删除。

    基于springmvc的jar包，

 

3.成果基本样式

4.详细内容

    HibernateTemplate的经常使用方法。
    delete(Object entity): 删除指定持久化实例。
    find(String queryString): 根据 HQL 查询字符串来返回实例集合。
    save(Object entity): 保存新的实例。
    update(Object entity): 更新实例的状态，要求entity 是持久状态。

主要就是一个增删改查的过程。上面这四个是咱们经常使用方法。

由于个人项目用到了hibernate的逆向工程，因此数据库是自动生成。

下面就写一个登陆实例，由于登陆是一个查询的过程，因此咱们将用find方法。

a.建立项目，导入jar包，这些我就不介绍了。

b.建立

com.controller,

com.dao,

com.model,

com.service

包，在里面分别创建java

usercontroller,

userdao,

user,

userservice

注意开头大写。

c.编写hibernate.cfg.xml

 

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/bgift?useUnicode=true&characterEncoding=UTF-8</property>
        <property name="connection.username">root</property>
        <property name="connection.password">1478</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="myeclipse.connection.profile">Bgift</property>
        <property name="show_sql">true</property>
	    <property name="format_sql">true</property>
	    <property name="hbm2ddl.auto">update</property>
	    <property name="hibernate.connection.autocommit">true</property> 
	    <mapping class="com.model.User" />
/////其中 mapping class="com.model.User"是要注意的。路径问题。

</session-factory> </hibernate-configuration>　

d.编写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <listener>  
        <listener-class>  
            org.springframework.web.util.Log4jConfigListener  
        </listener-class>  
    </listener> 	
    <!-- 字mvc -->

	</servlet-mapping>	
	<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
  <!-- 字符编码过滤器，结觉乱码问题 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>

	</filter-mapping>
	
	<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

　　e.编写applicationContext.xml

<?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:p="http://www.springframework.org/schema/p"

	</bean>	
	<tx:annotation-driven transaction-manager="transactionManager"/>
	<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
</beans>

　　f.编写com.model.user.java

package com.model;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="user")
public class User {

	int id;
    String username;
    String password;
    @Id
    @Column
    @GeneratedValue(strategy=GenerationType.AUTO)
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	@Column
    public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	 @Column
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}	 	
    
}

　　g.编写com.model.userdao.java

package com.dao;

import java.util.Date;
import java.util.List;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
 
import com.model.User;

@Repository
public class UserDao extends HibernateDaoSupport{
	@Resource
    public void setSessionFactoryOverride(SessionFactory sessionFactory){
	    super.setSessionFactory(sessionFactory);
	}

/////////////*登陆*//////////////////////////////*登陆*////////////////////////*登陆*/
	@SuppressWarnings("unchecked")
	public List<User> userlogin(User user){
		String hql= "from User where username=? and password=?";
		List<User>  t=this.getHibernateTemplate().find(hql,new Object[]{user.getUsername(),user.getPassword()});
		return t;
	}

}

　h.编写com.model.userservice.java　

package com.service;

import java.util.List;

import javax.annotation.Resource;
import org.springframework.stereotype.Component;
 
import com.dao.UserDao;
import com.model.User;

@Component
public class UserService {
	@Resource
	UserDao userdao;

	public UserDao getUserdao() {
		return userdao;
	}

	public void setUserdao(UserDao userdao) {
		this.userdao = userdao;
	}
/////////////*登陆*//////////////////////////////*登陆*//////////*登陆*/
	public List<User> userlogin(User user){
		 return userdao.userlogin(user);
		 
	 }

}

　　i.编写com.model.usercontroller.java

 

package com.Controller;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
import com.model.User;
import com.service.UserService;

@Controller
public class UserController {
	@Resource
	UserService userService;

	public UserService getUserService() {
		return userService;
	}

	public void setUserService(UserService userService) {
		this.userService = userService;
	}

/////////////*登陆*//////////////////////////////*登陆*/
	@RequestMapping("userlogin.do")
	public String findAll(HttpSession session,User user,HttpServletResponse response){	
    List<User> listuser = userService.userlogin(user);
    if(listuser.size()>0){
    	session.setAttribute("listuser", listuser);
        return "loginsuccess";	
    }else{
		response.setContentType("text/html; charset=UTF-8"); //转码
	    PrintWriter out;
		try {
			out = response.getWriter();
			out.flush();
		    out.println("<script>");
		    out.println("alert('帐号或密码错误！');");
		    out.println("history.back();");
		    out.println("</script>");
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}	   	    
    	return "index";
    }   
}

}

 

　　j.编写前台index.jsp

 <form name="formuser" id="formuser" method="post" action="userlogin.do">
	 <input type="text"   id="username" name="username" placeholder="请输入帐号" /><br /><br />		
	 <input type="password" class="index_mi"  id="password"  name="password" placeholder="请输入密码"  /><br /><br />	
         <input class="index_z_fi" type="submit"  value="登陆" /> 	
 </form>

 

 

k.编写前台loginsuccess.jsp
添加${sessionScope.listuser[0].username}
接受后台传来的session.setAttribute("listuser", listuser);值。

 

5.总结

   一个登陆写完，其实我只是把文件中的一部分赋值过来，便于了解。

在写这个系统以前，有过不少问题：

  a.路径问题，return 后面接jsp路径的话，要把路径写对，在提交时候XXX.do要写对。不然404。

  b.jar包冲突问题，当初困扰我好久，后来把冲突包删除，再发布后还会出现，索性把jar包都放到lib文件夹下。

  c.乱码，在web.xml下配置，相互传值要注意。比较好改。
