前端传递json，后端应该怎样接收呢？

Content-Type: application/json

#后端接收方式
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {

    /**
     * @param userForm
     */
    @PostMapping("/register")
    public ResponseVo register(@RequestBody UserForm userForm) {
        log.info("username={}", userForm.getUsername());
        }
 }
