spring mvc+hibernate 实现事务管理(配置文件版)-优快云博客

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

userDao

package com.test2.dao;

import com.test2.model.User;

public interface UserDao {

	public void save(User user);

userDaoImpl:

package com.test2.dao.impl;

}

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;

	}
}

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="..." οnclick="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。
