spring mvc get all request mappings

Question

We have a quite big spring mvc web application where the controllers are annotated with @Controller and the methods with @RequestMapping.

I would like to create a test now which checks every possible url and checks if the return value is 200.

Is it somehow possible to get all the mappings from spring ?

Answer 1

I am replicating one of my previous answers here:

If you are using Spring 3.1 this handlerMapping component is an instance of RequestMappingHandlerMapping, which you can query to find the handlerMappedMethods and the associated controllers, along these lines(if you are on an older version of Spring, you should be able to use a similar approach):

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

@Controller
public class EndpointDocController {
 private final RequestMappingHandlerMapping handlerMapping;

 @Autowired
 public EndpointDocController(RequestMappingHandlerMapping handlerMapping) {
  this.handlerMapping = handlerMapping;
 }

 @RequestMapping(value="/endpointdoc", method=RequestMethod.GET)
 public void show(Model model) {
  model.addAttribute("handlerMethods", this.handlerMapping.getHandlerMethods());
 } 
}

I have provided more details on this at this url http://biju-allandsundry.blogspot.com/2012/03/endpoint-documentation-controller-for.html
