Spring Async Question

[zxt47]

My Question: Hello, guys, I want to know When My Project using Spring Async Annotation in order to start another asynchronous task, I will lose the traceID and spanID in the Main Thread，In my opinion, the context can't inherited? just like this blow: 2019-09-05 10:54:11,449 [TUMSMsgService-1] c.t.p.i.b.g.TumsServiceImplExample INFO [ac16b07b1567652051440100111292,0] >Start handle TUMS msg.MsgType:ARP,MsgContent:Ich liebe dich then async begin: 2019-09-05 10:54:07,312 [SimpleAsyncTaskExecutor-3] worklog INFO [,] >orisys is RCT_MU 2019-09-05 10:54:07,321 [SimpleAsyncTaskExecutor-3] worklog INFO [,] >MODE is CLIENT 2019-09-05 10:54:07,321 [SimpleAsyncTaskExecutor-3] worklog INFO [,] >servicename is RCT_MU 2019-09-05 10:54:07,321 [SimpleAsyncTaskExecutor-3] worklog INFO [,] >connectnum_put is 1 2019-09-05 10:54:07,321 [SimpleAsyncTaskExecutor-3] worklog INFO [,] >econnectnum_get is 1 2019-09-05 10:54:07,321 [SimpleAsyncTaskExecutor-3] worklog INFO [,] >qnameget=RCT_MU_INPUT So how can I make the Spring Async have the Parent Thread's Span?

@zxt47 A simple implementation is to decorate the context of the current thread to the specified Runnable and finally reset the current thread context.

额，为什么这里不能使用InheritableThreadLocal或者阿里自研的transmittable-thread-local？ 这里：

/**
 * SofaTracerThreadLocalTraceContext

 * @since 2018/05/01
 */
public class SofaTracerThreadLocalTraceContext implements SofaTraceContext {

    private final ThreadLocal<SofaTracerSpan> threadLocal = new InheritableThreadLocal<>();

我这边通过自定义async的线程池，然后自定义线程池的TaskDecorator来实现的
