Problem in running a spring mvc app in intellij idea-CodePudding

I saw in a tutorial that he wanted to create a Spring MVC app and he also created the following files, but the continuation of the tutorial was in eclipse and I work with IntelliJ and I configured tomcat and when I run the program on it, the tomcat starts but the HTML page does not open.

CodePudding user response：

The IDE tries to run the application using an artifact at \spring_demo1\out\artifacts\artifact but I think it is the case only if you do not use Gradle or Maven. But since you use Spring Framework I believe you using one of them. In the case of Gradle, you have artifacts in /build/lib folder, and in the case of maven in the /target folder.

So something is messed up with the configuration.

Potentially IDE does not recognize your project as Gradle/maven.
Your 'build artifact' job from the configuration picture doesn't work, or creates an artifact in a different place.
