Today I had a junior developer come to me in a panic. He needed to provide a full report of all the security roles required for every endpoint in our services, to verify against requirements. His (valiant) attempts to grep the codebase were producing unreadable results, and we had an unexpected deadline of "now!"
Luckily, I knew that all of our request mappings are configured via annotations, and all the roles were also defined by annotations directly on the request mapping. So I added a random classpath scanning library I found, (https://sites.google.com/site/javacornproject/corn-cps) to the classpath of each service in IntelliJ, and fired up a Groovy console using the service's classpath. The following gist shows what I came up with:
Obviously, you'll need to update this if you do any configuration in XML, have Security annotations further down the stack, or use RequestMapping annotations at the class level. But the point is, the Groovy console in IntelliJ is your friend for quick one-off projects.
