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);

}

}
