First, let's take a look at the rough sequence diagram: Actionservlet is a central controller responsible for URL or distribution in the collection area; Actionform is responsible for collecting form data, and

, and the problem is more difficult to find in testing 2:singlethreadmodel Modify the servlet as follows public class UserId extends HttpServlet implements singlethreadmodel{ If the server implements Singlethreadmodel by queuing all requests, it can work, but if the village is heavily accessed concurrently, this approach can result in significant performance losses. If the server implements Singlethreadmodel by generating multiple instances of the servlet. This approach will fail completely beca
