This problem occurs because the class file is not found
is the MAVEN project
If you make sure that this org.springframework.web.context.ContextLoaderListener is already there, the problem is that Tomcat did not use the Web entry for the purpose of publishing the
Maven's dependency packages are packaged together as the project is compiled
Workaround:

1. Click on the Project-"Properties"
2. Select Deployment Assembly, click the Add button on the right, and select Java Build Path in the popup window Entries
3. Click Next to select Maven Dependencies (or select all dependent packages specified in the Pom.xml file)
4. Click Finish and you can see that maven dependencies has been added to the Web application structure
5. Restart Tomcat, test
