Springmvc could not find the corresponding requestmapping

1. Check if the annotations are correct.

2. Check whether the scan class is configured correctly in the configuration file.

3, if the above are correct but still cannot find the corresponding mapping, open the folder under the Tomcat WebApp the project Web-inf directory, find the Classes folder.

See if you can find the corresponding controller's class file. My problem is that the class file is not generated.

The reason is that I turned off automatic buildworkspace.

WORKAROUND:Project--->build automatically tick , then remove the project , right-click Tomcat in Eclipse, selectClean, Wait for the build workspace to finish and then add the project again, wait for the build workspace to complete and restart Tomcat, then open the Classes folder to find the corresponding classes file. And SPRINGMVC also found the corresponding requestmapping.
