Spring Cloud Zuul RateLimit

Module to enable rate limit per service in Netflix Zuul.
There are five built-in rate limit approaches:

• Authenticated User: Uses the authenticated username or 'anonymous'
• Request Origin: Uses the user origin request
• URL: Uses the request path of the upstream service
  • Can be combined with Authenticated User, Request Origin or both
• Authenticated User and Request Origin: Combines the authenticated user and the Request Origin
• Global configuration per service: This one doesn't validate the request Origin or the Authenticated User
  • To use this approach just don't set param 'type'

Adding Project Lombok Agent

This project uses Project Lombok to generate getters and setters etc. Compiling from the command line this shouldn't cause any problems, but in an IDE you need to add an agent to the JVM. Full instructions can be found in the Lombok website. The sign that you need to do this is a lot of compiler errors to do with missing methods and fields.
