Spring:Spring事务手动回滚方式

 

方法1:

在service层方法的catch语句中增加:TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();语句,手动回滚,这样上层就无需去处理异常(现在项目的做法)

 

方法2:

例如service层处理事务,那么service中的方法中不做异常捕获,或者在catch语句中最后增加throw new RuntimeException()语句,以便让aop捕获异常再去回滚,并且在service上层(webservice客户端,view层action)要继续捕获这个异常并处理

 

//普通缴费  
    @Transactional  
    public String commonMoney(Receipt rpt,Moneyrecord mors){  
        rpt.setState(1);  
        int a=dao.insert(rpt);  
        if(a<=0) return"缴费失败";  
        mors.setPric(rpt.getPic());  
        mors.setExid(rpt.getPid());  
        mors.setState(1);  
        boolean tf=mrs.custom(mors);  
        if(!tf){  
            //事务回滚
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();  
            return"余额不足";  
        }  
        return "OK";  
    } 

 

 

方法3:

设置回滚点进行回滚事务

//设置回滚点,
Object savePoint = TransactionAspectSupport.currentTransactionStatus().createSavepoint();  

//回滚到savePoint事务点
TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savePoint);
