无法从请求正文中读取

Question

I'm trying to send an email where the values are dependent on the values from the form in the Frontend, but they are always null.

Controller

    @PostMapping("/send")
    public void sendEmail(Contact contact) throws MessagingException {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setTo("test@gmail.com");
        mailMessage.setSubject(contact.getSubject()); //This is always null
        mailMessage.setFrom("arasto.developer@gmail.com");
        mailMessage.setText("To confirm ationToken()););");
        emailSenderService.sendEmail(mailMessage);
    }

Entity

public class Contact {

    private String email;
    private String address;
    private String subject;
    private String content;

    public Contact() { }

    //...getters & setters

My Post , This gives me 200 OK

Result Subject not being displayed.

Any suggestions of where i've gone wrong and how i could correct this are much appreciated.

Prepend method parameter with @RequestBody annotation as below:

public void sendEmail(@RequestBody Contact contact) throws MessagingException {
