How spring boot thymeleaf integrates webpack and vue

as mentioned above, I want to integrate vue + webpack into thymeleaf by accessing the index.html,index.html file under the vue folder in the controller layer as the entry file for vue.
in this way, if you directly access the springboot publishing port, you cannot access the vue service, and the index.html access is empty. At present, I intend to publish the vue service first and manually import the vue-compiled app.js file in index.html.

excuse me, how can I access the vue service directly from the springboot release port?

After the

page is done with vue, the static resources are generated by build, and the index.html is directly introduced into the build resources. The front and back ends of our project are completely separated, the page is written in vue, build is ready to publish directly, and then call the interface written by springboot
