3.项目目录结构

4.接口定义

package com.zhaochao.service;

public interface IAccountDao {
	public void addMoney(int id,int money);
	public void subMoney(int id,int money);
}

package com.zhaochao.service;

public interface IAccountService {
	public void giveMoney();
}

5.实现类

package com.zhaochao.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;

@Component("accountDao")
public class AccountDaoImple implements IAccountDao {
	@Autowired
	private JdbcTemplate jdbcTemplate;

	public void addMoney(int id, int money) {
		// TODO Auto-generated method stub
		jdbcTemplate.execute("update user_money set money=money-100 where id="+id);
		
	}

	public void subMoney(int id, int money) {
		// TODO Auto-generated method stub
		jdbcTemplate.execute("update user_money set  money=money+100 where id="+id);
	}

	
}

package com.zhaochao.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Isolation;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

@Service("accountService")
public class AccountServiceImpl implements IAccountService {
	
	@Autowired
	private IAccountDao accountDao;

	@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED)
	public void giveMoney() {
		// TODO Auto-generated method stub
		accountDao.subMoney(1, 100);
		int i=1/0;
		accountDao.addMoney(2, 100);
		
	}
	
	
	
	
}
