MAVEN Project Tomcat Controller 404

Today, using tomcat7.0.54 to start an existing MAVEN project, you can start normally, but all of your @controller comments are reported with a 404 error, and the next step is to troubleshoot the problem.

1. Starting to think it is the source problem, is not because of a key configuration dropped, so the current 404 error? But the same source code, there is no problem with colleagues, so that the source code is not a problem.

2. What is the problem? Get a working war package generated by colleagues, and deploy your own war packages and colleagues ' war packages locally, and find your own 404, compare the resulting file contents, and discover the web-inf/in the war package. The Lib folder has more dependent jar files, such as Maven dependencies, and the projects that you build don't have jar packages. The problem is positioned successfully, and here is the solution.

Right-click on the project-Properties-deployment assembly, found no MAVEN dependencies related items, add, and then run successfully.

Final result
