415（不受支持的媒体类型）

Question

while using POST using angularJS to the rest based controller in Spring MVC, I am getting 415 Media Type unsupported type. Can anybody please help in fixing the same.Below is the code for angularJS and Rest based controller.

AngularJS-

$http.post(urlBase + 'users/insert',$scope.user)
            .success(function(data) {
             $scope.users = data;   
             $scope.user="";
             $scope.toggle='!toggle';            
            });

Controller rest based -

 @RequestMapping(value="/users/insert",method = RequestMethod.POST,headers="Accept=application/json")
     public List<User> addUser(@RequestBody User user) throws ParseException      { 
       //setter methods for setting objects and sending to backend
}

Answer 1

I found the issue, have set some default value to due to which this issue was coming. $http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";

Corrected it to- $http.defaults.headers.post["Content-Type"] = "application/json";

For spring-mvc JSON-Java conversion, you need to have jackson libraries in your classpath

<dependency> 
       <groupId>org.codehaus.jackson</groupId>
       <artifactId>jackson-mapper-asl</artifactId>
       <version>1.4.2</version>
 </dependency>
