Java 通过POST请求。间谍安全。Rest模板。杰克逊转换器

我是Spring框架中的begginer，我想问你一个问题。 我如何通过正确的POST请求在DB中注册我的用户

我有一个Android客户端，我找到了使用web服务的唯一方法。 我正在使用AsyncTask管理请求

但我不知道如何通过我的

用户
类发送POST请求，以便在数据库中注册他。
数据库逻辑已经完成

我请求您帮助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 ?
    }
}

接下来是客户端（这里是一些MVP逻辑，但不是nvm）：

在服务器端：

有什么帮助吗？
您没有共享您的
用户
bean，但错误日志显示您试图访问
确认密码
字段，而只有
确认密码
。检查你的bean的getter名称。
是的，我已经修复了它。现在注册方法运行良好。我是a，只是登录方法有问题。
