Spring Eclipse (STS) @RequestMapping view is blank, is it because of Maven projects?
===

I'm using STS 2.7.2 for an existing Maven project. The web app runs perfectly fine in Tomcat. The structure is as follows:

 1. core
 2. service
 3. web
 4. war

So that's effectively 4 projects by Maven. I have added Spring project nature to all 4 and added the bean configurations (xml) for each project, however the Spring Tools > Show RequestMapping is still blank. I have tried triggering this command in all 4 project's config including the war's config set web-context.

I'm just wondering if anyone else may have similar project setup and has successfully viewed the RequestMapping functionality in STS?
