Sping Boot 3更改了跟踪中的上下文传播。https://github.com/micrometer-metrics/tracing/wiki/Spring-Cloud-Sleuth-3.1-Migration-Guide#async-instrumentation
他们现在提供了这个问题的库。我想我不太明白它是如何工作的。我已经创建了一个任务执行器作为指南。

@Bean(name = "taskExecutor")
    ThreadPoolTaskExecutor threadPoolTaskScheduler() {
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor() {
            @Override
            protected ExecutorService initializeExecutor(ThreadFactory threadFactory, RejectedExecutionHandler rejectedExecutionHandler) {
                ExecutorService executorService = super.initializeExecutor(threadFactory, rejectedExecutionHandler);
                return ContextExecutorService.wrap(executorService, ContextSnapshot::captureAll);
            }
        };
        threadPoolTaskExecutor.initialize();
        return threadPoolTaskExecutor;
    }

我把@Async标记为：

@Async("taskExecutor")
    public void run() {
        // invoke some service
    }

但上下文不会传播到taskExecutor线程中的子上下文。
