1. Go to /work/Catalina/localhost corresponding to tomcat and find the corresponding project folder. Delete it, or delete the /localhost folder directly. This step is just to clear the jsp cache. 2. Static files such as js/css files Add the version number at the end, such as /common.js?v=1.0 3. You can add no-cache restriction in the head to cancel the page cache
