Spring MVC 404 Not Found Error-free log solution

Scene description, using the Spring MVC framework for data preservation, using Firefox's firebug trace to find 404 Not Found.

Analysis: No error logs are printed in the background and the problem cannot be analyzed.

Solutions (provided by my friends)

Add a red section of the configuration file to the Spring-mvc.xml configuration file.

Add the Controlleradvicetest.java file under controller (note: must be under controller because Component-scan is configured in Spring-mvc.xml)

Run the background output the following error log again

It is clear that there is a problem with the object name and the problem is resolved. Attachment: Attach Controlleradvicetest.java Source code (Cannot add compressed package?) Please change the bag name yourself)
