Spring REST错误500

Question

I am implementing REST service using Spring. When i call delete function the request doesn't reach controller and from JS i receive error: angular.js:12587 DELETE http://localhost:8080/Guard_Server/restapi/sites?siteId=5 500 (Internal Server Error)

my controller function looks like:

@RequestMapping(value="sites", method=RequestMethod.DELETE)
boolean deleteSite(@PathVariable("siteId") int site_id, HttpServletResponse res){
    .......
}

And AngularJS function is:

$scope.deleteSite=function(){
            if(confirm("Are you sure you want to delete this Site?")){
                var site={};
                site.siteId=sites[$scope.selectedSite].id;
                console.log(site);
                siteFactory.delete(site).$promise.then(function(result){
                    ...
                }
                ,error_on_execute);
            }
        }

with factory:

serverApp.factory('referentFactory',['$resource',function ($resource){
   return $resource("http://localhost:8080/Guard_Server/restapi/referents",null,{ 'update': {method: 'PUT'} });
}]);

As I see in the url

http://localhost:8080/Guard_Server/restapi/sites?siteId=5

you should use @RequestParam instead of @PathVariable .

@RequestParam use for access query parameter and @PathVariable is part of url.

@RequestParam :

   http://localhost:8080/Guard_Server/restapi/sites?siteId=5

@PathVariable

   http://localhost:8080/Guard_Server/restapi/sites/siteId/5
