SpringBoot：使用REST服务发布新对象时的类型定义错误

Question

我有一个对象，它通过json POST请求获取参数，以便在数据库中创建一个新条目，但我得到以下错误：

    {
        "email": "[e-mail]"
    }

这是控制器

 @PostMapping("/forgot_password")
public ResponseEntity<?> processForgotPassword(@RequestBody HttpServletRequest request, Model model, User user) {
    String email = (String) request.getAttribute(user.getEmail());
    String token = RandomString.make(30);

    try {
        userService.updateResetPasswordToken(token, email);
        String resetPasswordLink = Utility.getSiteURL(request) + "/reset_password?token=" + token;
        sendEmail(email, resetPasswordLink);
        model.addAttribute("message", "We have sent a reset password link to your email. Please check.");

    } catch (ResourceNotFoundException ex) {
        model.addAttribute("error", ex.getMessage());
    } catch (UnsupportedEncodingException | MessagingException e) {
        model.addAttribute("error", "Error while sending email");
    }

    return ResponseEntity.ok("Reset link sent Successfully");
}

服务

public class UserService {

    @Autowired
    private UserRepository userRepository;


    public void updateResetPasswordToken(String token, String email) throws ResourceNotFoundException {
        User user = userRepository.findByEmail(email);
        if (user != null) {
            user.setResetPasswordToken(token);
            userRepository.save(user);
        } else {
            throw new ResourceNotFoundException("Could not find any user with the email " + email);
        }
    }

下面是一个示例，HttpServletRequest注入了不需要的@RequestBody，因此只需删除该注释即可。

@PostMapping("/forgot_password")
public ResponseEntity<?> processForgotPassword(HttpServletRequest request) {
  // do something
{

@requestbody表示从HTTP请求的主体构建一个对象，但HttpServletRequest是整个HTTP请求。是不匹配导致了错误。
