基于注解的事务管理配置文件：
（用 切面类 去模拟的）
切面类的代码如下：
package com.yidongxueyuan.spring.utils;import java.sql.Connection;import java.sql.SQLException;import org.aspectj.lang.annotation.AfterReturning;import org.aspectj.lang.annotation.AfterThrowing;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.springframework.stereotype.Component;@Component("TransactionManager")//告知spring该类是一个切面类@Aspect/** * 定义和事务相关的所有的方法： * 事物的开启 *///设置一个通用的切点表达式public class TransactionManager { private static ThreadLocal tl = new ThreadLocal (); public static Connection getConnection(){ Connection conn = tl.get(); if(conn == null){ conn = C3P0Util.getConnection(); tl.set(conn); } return conn; } @Pointcut(value="execution( * com.yidongxueyuan.spring.service.impl.AccountServiceImpl.*(..))") private void point1(){} @Before(value="point1()") public static void startTransaction(){ try { Connection conn = getConnection(); conn.setAutoCommit(false); } catch (SQLException e) { e.printStackTrace(); } } @AfterReturning(value="point1()") public static void commit(){ try { Connection conn = getConnection(); conn.commit(); } catch (SQLException e) { e.printStackTrace(); } } @AfterThrowing(value="point1()",throwing="e") public static void rollback(){ try { Connection conn = getConnection(); conn.rollback(); } catch (SQLException e) { e.printStackTrace(); } } //释放链接： public static void release() { Connection conn = getConnection(); try { conn.close(); } catch (SQLException e) { e.printStackTrace(); } }} 转载地址：http://czqen.baihongyu.com/
