How to scan classes for annotations?

Question

I have a plain jane servlets web application, and some of my classes have the following annotations:

@Controller
@RequestMapping(name = \"/blog/\")
public cl         


        

Answer 1

If you can get access of your .class files, then you may get the annotation using the class as below:

  RequestMapping reqMapping =  
                         TestController.class.getAnnotation(RequestMapping.class);
  String name = reqMapping.name(); //now name shoud have value as "/blog/"

Also please make sure, your classes are marked with RetentionPolicy as RUNTIME

  @Retention(RetentionPolicy.RUNTIME)
