spring mvc+hibernate 实现事务管理(配置文件版)

1，jar包支持

spring整合hibernate容易冲突的包：

jackson-core-asl-1.9.5.jar，jackson-mapper-asl-1.9.5.jar和spring的com.springsource.org.codehaus.jackson.mapper.jar，解决办法是删除spring自带的jar

还有就是 aoplliance.jar,asm.jar和cglib.jar冲突，结局办法是改变cglib.jar的版本，2.1改为2.2  2.2改为2.1

接下来，配置文件

项目结构：



User.hbm.xml:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.test2.model">

</id>
<property name="userName" column="username"
length="20" />
<property name="password" column="password"
length="20" />
</class>
</hibernate-mapping>

实体类User

package com.test2.model;

import java.io.Serializable;

public class User implements Serializable {

private String id;

private String userName;

private String password;

public User(){

}

public User(String userName,String password){
this.userName = userName;
this.password = password;
}

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String toString(){

return "user:id="+id+",userName="+userName+",password="+password;
}

}

userDao

package com.test2.dao;

import com.test2.model.User;

public interface UserDao {

public void save(User user);
}

userDaoImpl:

package com.test2.dao.impl;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;

import com.test2.dao.UserDao;
import com.test2.model.User;

public class UserDaoImpl extends  HibernateDaoSupport implements UserDao{
private SessionFactory sessionFactory;

@Override
public void save(User user) {

getHibernateTemplate().save(user);

}

}

userService:

package com.test2.service;

public interface UserService {

public void test();

}

userServiceImpl:

package com.test2.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;

import com.test2.dao.UserDao;
import com.test2.model.User;
import com.test2.service.UserService;

public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;

public UserDao getUserDao() {
return userDao;
}

public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}

@Transactional(rollbackFor=Exception.class)
public void test() {
User user1 = new User("zhangsan","111111");

User user2 = new User("lisi","222222222222222222222222222222");

userDao.save(user1);
System.out.println("user1 success");

userDao.save(user2);
System.out.println("user2 success");

}

}

UserController:

<pre name="code" class="java">package com.test2.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.test2.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {

@Autowired
private UserService userService;

public UserService getUserService() {
return userService;
}

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

@RequestMapping("/doTest")
@ResponseBody
public String doTest(){
userService.test();
return null;
}
}

UserTest.jsp:

<pre name="code" class="javascript"><%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
<jsp:include page="../common/easyui.jsp"></jsp:include>
<script type="text/javascript" charset="utf-8">
function aa(){
alert('aa');
$.ajax({
url :'${pageContext.request.contextPath}/user/doTest',
success : function (result){
alert(1);
}
});
}
</script>
</head>
<body class="easyui-layout" data-options="fit:true">
<input type="button" value="..." onclick="aa()"/>
</body>
</html>

前台用的是easyui

应对各种版本冲突，是不是用maven会好一点？

用maven是好一点，特别是发现一个版本不符合更换包的时候，只需要改几句话，不用添加删除包。

另外，不用数据库封装框架能实现spring的事务管理吗？

不能。
