When the method is marked @async, it allows developers to customize the pre-processing to meet functional requirements when performing asynchronous calls through a thread pool.
For example, you can customize ThreadFactory to pass information from ThreadLocal to asynchronous threads as ThreadName when you create a thread, and then perform pre-processing at the asynchronous call.
