按照網友的這篇文章，我使用springCloud搭建了一個demo

整合LCN之前，在一個本地事務中使用feign呼叫了其他服務，分布式事務不生效
整合LCN之后，Eureka注冊中心、tx_manager以及事務的發起方、參與方都可以正常啟動，但是在跑測驗類要測驗分布式事務時，報以下錯誤，

跟了一下代碼，是TransactionServerFactoryServiceImpl的createTransactionServer方法報的錯，好像是說netty服務的狀態不正常，我也不確定是到底是什么引起的問題，請使用過LCN的大咖指正一下，謝謝
public TransactionServer createTransactionServer(TxTransactionInfo info) throws Throwable {
if (info.getTransaction() != null && info.getTransaction().isStart() && info.getTxTransactionLocal() == null && StringUtils.isEmpty(info.getTxGroupId())) {
if (this.nettyService.checkState()) {
return this.txStartTransactionServer;
} else {
throw new Exception("tx-manager not connected ,please check tx-manager server ");
}
} else if (info.getTxTransactionLocal() == null && !StringUtils.isNotEmpty(info.getTxGroupId())) {
return this.txDefaultTransactionServer;
}
