spring Rest call through ajax - ajax

Question

I am stuck with a problem when i send POST request through ajax to Spring Rest i am getting following error. But it is working fine with Postman tool.
How to solve this? Please help.
#RestController
public class LoginController {
#Autowired
LoginServiceBo loginServiceBo;
public void setLoginServiceBo(LoginServiceBo loginServiceBo) {
this.loginServiceBo = loginServiceBo;
}
#RequestMapping(value="/login",method = RequestMethod.GET)
public ModelAndView redirectLoginForm() {
System.out.println("Login Page...");
return new ModelAndView("login");
}
#RequestMapping(value="/login",method=RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE, produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Login> login(#RequestBody Login login) {
System.out.println("Checking Login Credentials...");
boolean isValid=loginServiceBo.checkUserLogin(login);
if(isValid) {
System.out.println("Found...");
return new ResponseEntity<Login>(login, HttpStatus.ACCEPTED);
}
System.out.println("Not Found...");
return new ResponseEntity<>(login, HttpStatus.NOT_FOUND);
}
}
In javascript
function RestPost() {
userId = document.getElementById("userId");
password = document.getElementById("password");
var json = {
"userId": userId,
"password": password
};
$.ajax({
url: prefix + "/login",
type: 'POST',
data: JSON.stringify(json),
cache: false,
dataType: 'json',
beforeSend: function(xhr) {
xhr.setRequestHeader("Accept", "application/json");
xhr.setRequestHeader("Content-Type", "application/json");
},
success: function(response) {
alert(JSON.stringify(response));
},
error: function(jqXhr, textStatus, errorThrown) {
alert(jqXhr.status + ' ' + jqXhr.responseText);
}
});
}
