springboot2.1.2 + shiro1.4 + tx-lcn5.0.2 事务不回滚

- [ ] 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

Non lcn connection when clear transaction.

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

### 3. Exception Stacktrace

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

### 4. Tour Idea

Reproduce the transaction-clearance problem with JDK 1.8, Spring Boot 2.1.2, Shiro 1.4, and TX-LCN 5.0.2.RELEASE on Windows. Start by obtaining a real exception stack trace and a minimal reproduction; done means the non-LCN connection is cleared correctly and the transaction rolls back.
