Answer 1

For Spring 3.1 and above you can use ServletUriComponentsBuilder

@RequestMapping("/search/")     
     public ResponseEntity<?> searchWithSearchTerm(@RequestParam("name") String name) {  
         UriComponentsBuilder builder = ServletUriComponentsBuilder.fromCurrentRequest();
         System.out.println(builder.buildAndExpand().getPath());
         return new ResponseEntity<String>("OK", HttpStatus.OK);
     }

If you want the pattern, you can try HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE:

@RequestMapping({"/search/{subpath}/other", "/find/other/{subpath}"})
public Map searchWithSearchTerm(@PathVariable("subpath") String subpath,
                                             @RequestParam("name") String name) {

    String pattern = (String) request.getAttribute(
                                 HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE);
    // pattern will be either "/search/{subpath}/other" or
    // "/find/other/{subpath}", depending on the url requested
    System.out.println("Pattern matched: "+pattern);

}

Having a controller like

@Controller
@RequestMapping(value = "/web/objet")
public class TestController {

    @RequestMapping(value = "/save")
    public String save(...) {
        ....
    }
}

You cant get the controller base requestMapping using reflection

// Controller requestMapping
String controllerMapping = this.getClass().getAnnotation(RequestMapping.class).value()[0];

or the method requestMapping (from inside a method) with reflection too

//Method requestMapping
String methodMapping = new Object(){}.getClass().getEnclosingMethod().getAnnotation(RequestMapping.class).value()[0];

Obviously works with an in requestMapping single value.

Hope this helps.

@RequestMapping("foo/bar/blub")     
public Map searchWithSearchTerm(@RequestParam("name") String name, HttpServletRequest request) {
  // delivers the path without context root 
  // mapping = "/foo/bar/blub"
  String mapping = request.getPathInfo();
  // more code here
}

It seems you are looking for the path that this request has matched, then you can directly get it from servlet path

@RequestMapping("/search/")     
 public Map searchWithSearchTerm(@RequestParam("name") String name, HttpServletRequest request) {    
String path = request.getServletPath();
        // more code here     
 }
