问题:当事务失败返回一个需要的值进行后续的判断
@Transactional(propagation=Propagation.REQUIRED,timeout = 30000,isolation = Isolation.SERIALIZABLE)
@Override
public Map transfer(String outer, String inner, int money) {
Map<String,Object> map = new HashMap<String, Object>();
try {
accountDao.out(outer, money);
int i =1/0;
accountDao.in(inner, money);
map.put("flag", true);
} catch (Exception e) {
//手动回滚
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
//返回自己想要的值
map.put("flag", false);
}
return map;
}
详解:
在aop配置事务控制或注解式控制事务中,try...catch...会使事务失效,可在catch中抛出运行时异常throw new RuntimeException(e)或者手动回滚TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();使得事务生效,异常回滚。
