HmilyTransaction hmilyTransaction = executor.preTry(point);
try {
//execute try
returnValue = point.proceed();
hmilyTransaction.setStatus(HmilyActionEnum.TRYING.getCode());
//假设执行到此处宕机，此时Transaction 和 Participant status应该还是PRE_TRY?
executor.updateStartStatus(hmilyTransaction);

然后在Recovery时：
for (HmilyParticipant hmilyParticipant : hmilyParticipantList) {
....
这里判断是PRE_TRY，直接continue
if (hmilyParticipant.getStatus() == HmilyActionEnum.PRE_TRY.getCode()) {
//try not complete
continue;
}
final boolean successful = hmilyRepository.lockHmilyParticipant(hmilyParticipant);
// determine that rows > 0 is executed to prevent concurrency when the business side is in cluster mode
if (successful) {
LOGGER.info("hmily tcc transaction begin self recovery: {}", hmilyParticipant.toString());
HmilyTransaction globalHmilyTransaction = hmilyRepository.findByTransId(hmilyParticipant.getTransId());
if (Objects.isNull(globalHmilyTransaction)) {
tccRecovery(hmilyParticipant.getStatus(), hmilyParticipant);
} else {
//这里transaction状态也是PRE_TRY？
tccRecovery(globalHmilyTransaction.getStatus(), hmilyParticipant);
}
}
}

   最后没cancel，也没commit，悬挂了？
   
   不知道理解对不对。可能还有其他地方没看到。
