多线程开启组装数据，对所有非事务操作前置

场景:主流程在历史业务下，越来越繁琐，臃肿，不得不加一堆校验和组装数据，主流程下对多个主表数据操作，记录完本地数据后，调用rpc。

高峰调用

TP95

改造思路：

多线程开启组装数据，对所有非事务操作前置，对大事务拆分，减少重复查询数据，异步更新数据。

异步操作改造

 TransactionSynchronizationManager.registerSynchronization(new TransactionSynchronizationAdapter() {
                    @Override
                    public void afterCommit() {

                            handleSync(entruckingOrderDetailDo);
                        }

                } finally {
                    downLatch.countDown();

原子标识判断是否异常

before

代码语言：javascript复制

boolean flag = false;
Repository.insertBatch(xxx).var
Repository.insertBatch(xxx).var
Repository.insertBatch(xxx).var
if(flag){
   handlerSyncData();
}

after

代码语言：javascript复制

 AtomicBoolean  entruckFlag = new AtomicBoolean(false);
            if(!entruckFlag.get()){
                try {
                Repository.insertBatch(xxx).var
                Repository.insertBatch(xxx).var
                Repository.insertBatch(xxx).var
                    log.warn("持久化明细表:");
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            if(!entruckFlag.get()){
                handlerSyncData();
            }

对于重复调用数据查询前置

before

代码语言：javascript复制

for (Response.LogItem logItem : logItemList) { OrderDOentruckingOrder = OrderRepository.getOrder(logItem.getCode(), logItem.getEntruckingCode());    for (PackageConvertResponse packageConvertResponse : packageConvertResponseList) {          OrderDOentruckingOrder = OrderRepository.getOrder(logItem.getCode(), logItem.getEntruckingCode());          EntruckingOrderDO entruckingOrderDO1 = entruckingOrderMapper.selectOne(entruckingOrderDO);       }}

after

代码语言：javascript复制

for (Response.LogItem logItem : logItemList) {

 OrderDO  Order = OrderRepository.getOrder(logItem.getCode(), logItem.getEntruckingCode());
    for (PackageConvertResponse packageConvertResponse : packageConvertResponseList) {
      Order.getxxx
    }
}
