4. Tour Idea

 DefaultDTXExceptionHandler 异常处理器 ex为空导致 ex.getCause报错 最终无法执行结束事务
@Override
    public void handleNotifyGroupBusinessException(Object params, Throwable ex) {
        List paramList = (List) params;
        String groupId = (String) paramList.get(0);
        int state = (int) paramList.get(1);
        String unitId = (String) paramList.get(2);
        String transactionType = (String) paramList.get(3);

        //用户强制回滚.
        if (ex instanceof UserRollbackException) {
            state = 0;
        }
        if ((ex.getCause() != null && ex.getCause() instanceof UserRollbackException)) {
            state = 0;
        }

        // 结束事务
        try {
            transactionCleanTemplate.clean(groupId, unitId, transactionType, state);
        } catch (TransactionClearException e) {
            txLogger.error(groupId, unitId, "notify group", "{} > clean transaction error.", transactionType);
        }
    }

5.02版本，我在发起方打个断点后，出现如下提示 java.lang.NullPointerException: null at com.codingapi.txlcn.tc.core.checking.DefaultDTXExceptionHandler.handleNotifyGroupBusinessException(DefaultDTXExceptionHandler.java:93) at com.codingapi.txlcn.tc.core.template.TransactionControlTemplate.notifyGroup(TransactionControlTemplate.java:156) at com.codingapi.txlcn.tc.core.transaction.lcn.control.LcnStartingTransaction.postBusinessCode(LcnStartingTransaction.java:69) at com.codingapi.txlcn.tc.core.DTXServiceExecutor.transactionRunning(DTXServiceExecutor.java:108) at com.codingapi.txlcn.tc.aspect.weave.DTXLogicWeaver.runTransaction(DTXLogicWeaver.java:96) at com.codingapi.txlcn.tc.aspect.TransactionAspect.runWithLcnTransaction(TransactionAspect.java:93) at sun.reflect.GeneratedMethodAccessor454.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:45005) at java.lang.reflect.Method.invoke(Method.java:498) at org.springframework.aop.aspectj.AbstractAspectJAdvice.invokeAdviceMethodWithGivenArgs(AbstractAspectJAdvice.java:644)

而且后续，所有业务都无法进行下去了。急求解决

调用方注解事务级别设置成required

CrazyShaQuiShi commented 5 years ago

调用方已经是required了，改了测试还是不行。且场景容易重现，比如可以再调用方估计打个断点，然后等待超时，超时后就出现这个清情况了。而且之后及时去掉断点，接口无法请求，报同样的错误。 @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class) @LcnTransaction @Override public void commit(AgentContractInput input, Long userId) {

CrazyShaQuiShi commented 5 years ago

我尝试断点追踪发现 ex是null,我该如何解决，我可以如果是null直接给state=0吗？尝试修改若是null直接给0发现发起方事务回滚了。可是被调用方，事务没回滚。产生了数据

@LcnTransaction(propagation = DTXPropagation.REQUIRED) 中加，对于数据库超时请回到我的那问题，重写TransactionControlTemplate 的 notifyGroup 方法 catch (LcnBusinessException e) { // 关闭事务组失败 dtxExceptionHandler.handleNotifyGroupBusinessException(Arrays.asList(groupId, state, unitId, transactionType), e); }

我尝试断点追踪发现 ex是null,我该如何解决，我可以如果是null直接给state=0吗？尝试修改若是null直接给0发现发起方事务回滚了。可是被调用方，事务没回滚。产生了数据 tx服务端事务时间设置长一点，如果超过此长度分布式事务就无法生效
# 分布式事务执行总时间(ms). 默认为36000
tx-lcn.manager.dtx-time=60000

好的，晓得了。其实我可以理解成，如果在分布式事务中，总耗时大于tx-lcn.manager.dtx-time设置的时间，其实事务是不起作用的对吧。

是的

这个问题怎么解决那，是设置事务执行总时间长一点，还是修改代码ex为null的时候，返回state=0。这个问题应该不是超时引起的把，我执行时间应该没有超时，但是还是关闭失败，报空指针了
