Quick little POC for self-documenting the controller layer in a SpringMVC app

ApiDocExample.java

public class ApiDocExample{
  @Inject
	private RequestMappingHandlerMapping mapping;

  public void foobar(){
    Map<RequestMappingInfo, HandlerMethod> map = mapping.getHandlerMethods();
		
		for( RequestMappingInfo info : map.keySet() ){
			HandlerMethod method = map.get(info);
			ApiOperation annotation = method.getMethodAnnotation(ApiOperation.class);
			if( annotation != null ){
				String className = method.getBeanType().getSimpleName();
				Set<String> patterns = info.getPatternsCondition().getPatterns();
				MethodParameter rt = method.getReturnType();
				String rtc = rt.getParameterType().getSimpleName();
				
				System.out.println( rtc + " " + className + "(" + patterns + ")");
				
				
			}
			
		}
  }
}
