The controller invokes the corresponding view to display the processing structure. and renders it to the user through a view.

Web server sends answer header informationJust as the client sends information about itself along with the request, the server also sends the user with the answer about its own data and the requested document. Web server sends data to browserAfter the Web server sends the header information to the browser, it sends a blank line to indicate that the header in

Java Basic pen Questions (iii) What is Threadlocal,threadlocal's role? As explained in the JDK documentation: the role of threadlocal is to provide local variables within a thread that, when accessed in a multithreaded environment, can guarantee the independence of variables in each thread. It can be seen from here that the purpose of introducing threadlocal is to provide local variables within the thread,
