UserServiceImpl.java（Service层，通过注解配置事务）：

package cn.xxx.service.impl;

import org.springframework.transaction.annotation.Isolation;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import cn.xxx.dao.UserDao;
import cn.xxx.domain.User;
import cn.xxx.service.UserService;

@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=true)
//通过注解配置事务(类上一般配置 readOnly=true)
public class UserServiceImpl implements UserService{
	
	private UserDao ud;

	@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=false)
	//通过注解配置事务(修改数据库的方法上一般配置 readOnly=false)
	public void saveUser(User u) {
		ud.save(u);
	}

	public void setUd(UserDao ud) {
		this.ud = ud;
	}

}

Test.java（测试类）：

package cn.xxx.test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import cn.xxx.domain.User;
import cn.xxx.service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class Test {
	
	@Resource(name="userService")
	//注入Service层对象
	private UserService us;
	@Test
	//测试aop事务
	public void fun1(){
		User u = new User();
		
		u.setUser_code("Jack");
		u.setUser_name("杰克");
		u.setUser_password("1234");
		
		us.saveUser(u);
	}
