Spring事务

1.导入依赖

    
        
            mysql
            mysql-connector-java
            5.1.47
        
        
            com.alibaba
            druid
            1.0.15
        
        
            org.springframework
            spring-jdbc
            5.0.8.RELEASE
        
        
            org.springframework
            spring-tx
            5.0.8.RELEASE
        
        
            org.springframework
            spring-context
            5.0.8.RELEASE
        
        
            junit
            junit
            4.12
            compile
        
    

2.配置XML文件

3.声明事务

@Service
//对类内所有的方法都开启事务
@Transactional
public class AccountService {
    @Autowired
    private AccountDao accountDao;
    public void executeMoney(){
        accountDao.subMoney("1",500);
        int a = 1 / 0;
        accountDao.addMoney("2",500);
    }
}
