Spring task calls two times a question at a time

In a recent spring MVC project, you need to perform a task regularly, so you use spring's own task functionality. When debugging locally, everything is fine, but once deployed to the server, each task is called two times. After searching for related problems on the Internet, excluding the problem of repeating annotations, we found that the Tomcat configuration item was placed in the WebApp directory, and the docbase= "project path" was configured in the Server.xml configuration file to cause the container to be initialized two times. Finally, move the project out of the WebApp directory and specify the path in the Docbase to resolve the problem.
