Ajax request to Spring REST api 415 error

Question

I have a problem with my Spring Rest controller. I am trying to post (PUT) data from my client (angularJS) to my server (Spring), but every time I try to send something I get a 415 Media not supported error.

With Maven I have added jackson-core (2.6.3) and jackson-databind (2.6.3) to my Spring API. I am also using @EnableWebMvc to automatically add the Jackson message converter to Spring. In my Spring controller I am using @RestController for access to the REST methods of Spring.

My REST API controller:

@RequestMapping(value = "/location/update/{id}", method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE) public RippleUser updateUserLocation(@PathVariable("id") Integer id, @RequestBody RippleUser user) { return user; }

I have tried differend types of consumes:

MediaType.APPLICATION_JSON_VALUE
"application/json"
Without consumes
And so on

My RippleUser model (partially)

@Entity @Table(name = "user") @JsonRootName(value = "user") public class RippleUser implements Serializable { @NotNull @Column(name = "active", nullable = false) private boolean activeUser; @Column(name = "latitude", nullable = true) private Float lattitude; @Column(name = "longitude", nullable = true) private Float longitude; @Temporal(TemporalType.TIMESTAMP) @Column(name = "lastActive", nullable = true) @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy HH:mm:ss") private Date timestamp; }

In this model I have all the necessary getters and setters.

My AngularJS client:

 httpService.updateInBackend = function (url, data, callback, errorCallback) { http.put(url, data) .then(function successCallback(response) { callback(response.data); }, function errorCallback(response) { errorCallback(response); }); };

The URL: http://server:port/app/location/update/{id}

The data:

params: { { "user": { "latitude": 52.899370, "longitude": 5.804548, "timestamp": 1449052628407 } } };

For this method I also added @JsonRootName(value = "user") to my RippleUser model.

I have also tried without the user attribute (also removed it from my model):

params: { { "latitude": 52.899370, "longitude": 5.804548, "timestamp": 1449052628407 } };

The AngularJS HTTP method (PUT, POST, DELETE, GET, and so on) checks what type is in the parameters and automatically sets the right headers.

Chrome Postman

Just to make sure I have also tried this method in the Chrome Postman plugin

The URL: http://server:port/app/location/update/2

Method: PUT

Headers: Content-Type: application/json

Body:

{ "latitude": 52.899370, "longitude": 5.804548, "timestamp": 1449052628407 }

The error this gives is:

HTTP Status 415 The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.

Update

I can receive information in my RestController when I change my @ResponseBody from RippleUser to String:

@RequestMapping(value = "/location/update/{id}", method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE) public RippleUser updateUserLocation(@PathVariable("id") Integer id, @RequestBody String user) { return user; }

I also tried sending an empty user object, but that results in the same error message

Answer to my problem is below.

So you method has a type of RippleUser, and you are returning a String? — OPK

@Jason Z, that was just to test if I could get trough the method. I got a Json string back, so the method works. The code was just for testing purposes — Mr.wiseguy

The problem with this code is a bit different than I expected. The 415 media not supported error is thrown by Spring, because it could not fill in all the required fields with the post.

My solution was to add a class especially used by Spring to convert data to and from while sending and receiving. The benefit of this extra class is that I can manage the data the API sends and receives.

UserLocation

Adding the following class to my project did the trick (with getters and setters):

public class UserLocation { private Float latitude; private Float longitude; private Date lastActive; }

This class contains all the necessary data for my PUT request. Spring automatically fills in all the fields.

Controller

To make this work I also had to modify my controller. The new code is as follows:

@RequestMapping(value = "/location/update/{id}", method = RequestMethod.PUT) public UserLocation updateUserLocation(@PathVariable("id") Integer id, @RequestBody UserLocation location) { //Find user by ID //Add location to user //Update the user return //the new user }

Hope this helps anyone
