我需要在taskdecorator中找出@async方法名。如何从taskdecorator中找出方法名（asyncmethodwithreturntype），或者有更好的方法找出在SpringBoot2中用@async注解的实际方法？

@Bean(name = "threadPoolTaskExecutor")
public Executor threadPoolTaskExecutor() {
    ThreadPoolTaskExecutor th =  new ThreadPoolTaskExecutor();
    // HERE AUDIT WOULD collect metric about method name.
    th.setTaskDecorator(runnable -> AuditWrapper.auditWrapper(runnable)) 

}

@Async
public Future<String> asyncMethodWithReturnType() {
    System.out.println("Execute method asynchronously - " 
      + Thread.currentThread().getName());
    try {
        Thread.sleep(5000);
        return new AsyncResult<String>("hello world !!!!");
    } catch (InterruptedException e) {
        //
    }

    return null;
}

请让我知道，如果你有任何更好的建议，以找出实际的方法正在执行。我需要收集方法名称以用于审核/模拟目的。
