使用Spring Restful Web Service时遇到org.springframework.web.servlet.PageNotFound.noHandlerFound错误

Question

I am using spring restful webservice along with angular JS. I am trying to connect with my backend code but could not able to do so. I am not able to figure out where exactly I am going wrong.

Here is my angular code :

app.constant('REST_URI', 'http://localhost:8181/rest/');

app.factory('FeedbackService',['$http', 'REST_URI', function ($http, REST_URI) {

    const addFeedbackAPI = REST_URI + 'feedback/addFeedback';

    var addFeedback = function(feedbackData){
        return $http.post(addFeedbackAPI, feedbackData);
    };

   return {
       addFeedback : addFeedback
   };

}]);

app.controller('feedbackController', ['$scope', 'FeedbackService', function ($scope, FeedbackService) {

    $scope.feedbackData = {};

    $scope.addFeedback = function () {

        $scope.feedbackData.registerDate = new Date();

        FeedbackService.addFeedback($scope.feedbackData).then(
            function (successResponse) {
                $scope.feedbackResponse = successResponse;
            },
            function (errorResponse) {
                $scope.feedbackResponse = errorResponse;
            }
        );
    };
}]);

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

    <servlet-mapping>
        <servlet-name>springrest</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>

</web-app>

Controller

@RestController(value = "/rest/feedback/")
public class FeedbackController {

    @Autowired
    private FeedbackService feedbackService;

    @RequestMapping(value = "addFeedback", method = RequestMethod.POST)
    public long addFeedback(@RequestBody Feedback feedback) {
        return feedbackService.addFeedback(feedback);
    }
}

But I am getting 404 error in logs :

console :

http://localhost:8181/rest/feedback/addFeedback 404 ()

server : 01-Feb-2017 10:05:49.339 WARNING [http-nio-8181-exec-9] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/rest/feedback/addFeedback] in DispatcherServlet with name 'springrest'

Answer 1

use @RestController(value = "/feedback/")

instead of @RestController(value = "/rest/feedback/")

because you have already used /rest/* in your web.xml you need not to give this in java controller.
