Description

看issue发现很多人也有这个问题,我最近也碰到了,然后跟踪了一下源码,总算解决了。

下面给出我的解决步骤:

1. 打开LCN Logger
`logging.level.com.codingapi.txlcn = debug`

2. 检查日志中是否包含以下log。如包含,转6
`com.codingapi.txlcn.tracing.Tracings : tracing apply group:693a5ae3226537.....`

3. 检查日志中的各服务log中groupId是否一致 。如一致,转6
`c.c.t.t.c.context.DefaultGlobalContext : Start TxContext[693a5ae3226537]`

4. 检查是否用了 @EnableWebMvc 注解。如用了,转6
5. 添加MVC拦截器
```
public class WebMvcConfiguration extends WebMvcConfigurationSupport {
.........其它配置省略...........
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new SpringTracingApplier());
}
}
6. 结束
```
