I'm trying to post a JSON Object, with Ajax, to an Rest Spring MVC Controller, but I met some troubles.
Let's present you my code:
Controller
@RequestMapping(value = "/register/checkUsername.html", method = RequestMethod.POST, produces=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody JsonResponse checkUsername(@RequestBody JsonUsername username) {
String usernameString = username.getUsername();
JsonResponse response = new JsonResponse();
response.setMessage(usernameString + "Available");
return response;
}
Ajax Function
function displayUsernamError(data) {
var json = "<h4>Eroare</h4><pre>"
+ JSON.stringify(data, null, 4) + "</pre>";
$('#usernameError').html(json);
}
function checkUsername(){
var username = document.getElementById("username");
var search = {
"username" : username.value
}
$.ajax({
type : "POST",
contentType : 'application/json; charset=utf-8',
dataType : 'json',
url : "http://localhost:8080/skill-assessment/register/checkUsername.html",
data : JSON.stringify(search),
success : function(result) {
console.log("SUCCESS: ", data);
displayUsernamError(result);
},
error: function(e){
console.log("ERROR: ", e);
displayUsernamError(e);
},
done : function(e) {
console.log("DONE");
}
});
}
And finally the html form:
<form:form modelAttribute="user" method="POST" enctype="utf8">
<tr>
<td><label>Username</label></td>
<td><form:input path="name" id="username" /></td>
<td>
<p id="usernameError">
</p>
</td>
</tr>
<button type="button" onClick="checkUsername()">Register</button>
</form:form>
So, I'm calling the checkUsername method when I press click on the Register button, only for test.
The ajax function is called and this send the JSON to the controller. I used the debug and the controller seems to get the JSON Object.
The problem is with the controller Response, because in the error div from my html page, I get this error:
HTTP Status 406 The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request \"accept\" headers.
Where is the problem? Who can give me an idea?
