【问题描述】：

我是 Spring 框架的初学者，我想问你一个问题。 我如何正确传递 POST 请求以在数据库中注册我的用户。

我有一个 android 客户端，我找到了使用网络服务的唯一方法。 我正在使用 AsyncTask 来管理请求。

但我不知道如何使用我的User 类发送 POST 请求以将他注册到数据库中。 数据库的逻辑已经完成。

我请你帮我如何发布请求以及如何在服务器上管理他。

这是我的代码：

服务器端，用户控制器：

@RestController
@RequestMapping("/user")
public class UserController 

    @Autowired
    private UserService userService;

    @Autowired
    private SecurityService securityService;

    @Autowired
    private UserValidator userValidator;


    @RequestMapping(value = "/registration", method = RequestMethod.POST)
    @ResponseBody
    public User registration(@RequestBody User user, BindingResult bindingResult, Model model) 
        userValidator.validate(user, bindingResult);// here is validate logic
        if (bindingResult.hasErrors()) 
            //What should i return here to my Android client ?
        
        userService.save(user);
        securityService.autoLogin(user.getUserName(), user.getConfirmPassword());
        return user;
    

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String login(Model model, String error, String logout) 
        if (error != null) 
            model.addAttribute("error", "Username or password is incorrect.");
        

        if (logout != null) 
            model.addAttribute("message", "Logged out successfully.");
        

        return "login";// what should I return to the client ???
        //How my android client will understand that user is loged in ?
    

接下来我有客户端（这里有一些 MVP 逻辑，但 nvm）：

public class CreateAccountPresenter implements CreateAccountContract.Presenter 
    private CreateAccountContract.View view;
    private String userName;
    private String userPassword;
    private String confirmUserPassword;


    public CreateAccountPresenter(CreateAccountContract.View view) 
        this.view = view;
    

    @Override
    public void onCreateAccountClick() 
        userName = view.getUserName();
        userPassword = view.getPassword();
        confirmUserPassword = view.getPasswordConfirmation();
        new CreateAccountTask().execute();

    

    private class CreateAccountTask extends AsyncTask<Void, Void, User>
        // How do I properly pass the post request with my User object ?
        @Override
        protected User doInBackground(Void... voids) 
            RestTemplate restTemplate = new RestTemplate();
            restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
            User user = new User(userName, userPassword, confirmUserPassword);
            return restTemplate.postForObject(URL.getUserRegistration(), user, User.class);
        

        @Override
        protected void onPostExecute(User user) 
            view.makeToast("User registration complited " + user.getUserName());
        
    

我需要在客户端初始化转换器吗？ 寻求帮助，如果您在 cmets 中发布一些代码也将很棒。

更新 我更改了一点客户端代码，现在我在客户端收到下一个错误：

在服务器端：

2254021 [http-apr-8080-exec-2] WARN org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver - Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Unrecognized field "confirmationPassword" (class com.webserverconfig.user.entity.User), not marked as ignorable (4 known properties: "id", "confirmPassword", "userName", "userPassword"])

 at [Source: java.io.PushbackInputStream@2cbfcb7c; line: 1, column: 26] (through reference chain: com.webserverconfig.user.entity.User["confirmationPassword"])

有什么帮助吗？

【参考方案1】：

您没有共享您的User bean，但错误日志显示您正在尝试访问字段confirmationPassword，而只有confirmPassword。检查 bean 的 getter 名称。

【讨论】：

是的，我已经解决了。现在注册方法工作正常。我一个，只有登录方法有问题。
