Passing String from angular to Spring using #Requestbody - angularjs

Question

I am working on a project using angularjs+springboot. Am trying to send email via my application using spring-boot-starter-mail. The message and object of the email are written by the user in a form. what I want to do is to get the message and object values in my RestController using #RequestBody.
the function in my service.js
// send mail
var sendMail = function(id, objet, msg) {
var deferred = $q.defer();
$http.post(urlBase + id, objet, msg).then(
function(response) {
deferred.resolve(response.data);
}, function(errResponse) {
console.error('Error while sending email');
deferred.reject(errResponse);
});
return deferred.promise;
}
the method in my restContoller
#RestController
public class EmailController {
#Autowired
private JavaMailSender javaMailSender;
#Autowired
UtilisateurService service;
#RequestMapping(value = "/users/{id}", method = RequestMethod.POST)
public ResponseEntity<Void> sendMail(#PathVariable("id") int id, #RequestBody String objet,
#RequestBody String msg) {
Utilisateur currentUser = service.findById(id);
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(currentUser.getEmailUtil());
message.setSubject(objet);
message.setText(msg);
javaMailSender.send(message);
return new ResponseEntity<Void>(HttpStatus.OK);
}}
This throws this exception :
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public org.springframework.http.ResponseEntity<java.lang.Void> com.sla.utilisateur.controller.EmailController.sendMail(int,java.lang.String,java.lang.String)
How can I fix it?
thank you,

Your usage of $http.post is not correct. You should have a look at the AngularJS POST documentation. $http.post arguments are the following:
post(url, data, [config]);
AngularJS sends the data by default in JSON. So you should send the request using the following statement (for example):
$http.post(urlBase + id, {subject:objet, body:msg})
And in your controller you should define only one #RequestBody maps for the ease of the example to a Map (You could change it to a POJO. ):
#RequestMapping(value = "/users/{id}", method = RequestMethod.POST)
public ResponseEntity<Void> sendMail(#PathVariable("id") int id, #RequestBody Map<String,String> msg) {
Utilisateur currentUser = service.findById(id);
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(currentUser.getEmailUtil());
message.setSubject(msg.get("subject");
message.setText(msg.get("body"));
javaMailSender.send(message);
return new ResponseEntity<Void>(HttpStatus.OK);
}}
