Passing String from angular to Spring using @Requestbody

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,

change ResponseEntity<Void> to ResponseEntity<String>

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);
}}
