Record an error that the Tomcat resource publication cannot be updated:

When it is found that Tomcat information is not updated after it is published, it is still the same as before; restart tomcat, delete the generated war package, and then re open it, it is found that there is no effect. After checking the configuration, it is found that there is no error. Check the resources under the published war package, and all the resources of the project are successfully published

So, after repeated operations, we finally found the error – the browser’s cache data is not cleared, delete the browser’s cache, restart, OK! No problem, Laotie

I hope my question will help you
