服务A调用服务B，两个服务中都有更新操作，服务A做完更新操作后未提交事务，服务B卡死等待

- [ ] I have searched the [issues](https://github.com/codingapi/tx-lcn/issues) of this repository and believe that this is not a duplicate.

### 1. Bug Description

### 2. Environment:
- JDK version: 1.8
- OS:
- TX-LCN version:5.0.2.RELEASE
- Others:

### 3. Exception Cause: java.sql.SQLException: Lock wait timeout exceeded; try restarting transaction

```
Paste your Exception Stacktrace here!
```

### 4. Tour Idea

The report identifies TX-LCN 5.0.2.RELEASE, JDK 1.8, and a lock-wait timeout when service A calls service B. No source files, tests, stack trace, or reproduction steps are provided, so those details must be supplied before a contributor can identify the entry point or verify a fix.
