java传递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
但是我不知道如何用我的User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 安卓 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）：
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？ 如果你在评论中发布一些代码，寻求帮助也会很棒
更新 我更改了一点客户端代码，现在客户端出现下一个错误：

需要帮忙吗

您没有共享
Userbean，但错误日志显示您试图访问字段confirmationPassword，而只有confirmPassword。检查bean的getter名称
