Question

我是开发工具的新手，我正在尝试使用带百里叶的spring来创建一个在网站上注册的表单。我目前无法将表单中的信息恢复到仅显示用户列表的另一个页面。我在Eclipse中使用model / service / dao / controller java文件创建了一个经典的Spring启动安全性。

我的模型java文件 - ＆gt; Register.java

@Entity
public class Register {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    private String pseudo;
    private String lastname;
    private String firstname;
    private String sex;
    private String country;
    private String phone;
    private String spokenlanguages;
    private String email;
    private String password;
    private String job;
    private boolean premium;

    public void updateRegister(String pseudo, String lastname, String firstname, String sex, String country, String phone,
            String spokenlanguages, String email, String password, String job, boolean premium) {
        this.pseudo = pseudo;
        this.lastname = lastname;
        this.firstname = firstname;
        this.sex = sex;
        this.country = country;
        this.phone = phone;
        this.spokenlanguages = spokenlanguages;
        this.email = email;
        this.password = password;
        this.job = job;
        this.premium = premium;
// with all the getters & setters
    }

My Service java file --> RegisterService.java

    public interface RegisterService {
    public List<Register> list();
    public Register getById(long id);
}

我的存储库Java文件 - ＆gt; RegisterRepository.java

    @Repository
public interface RegisterRepository extends PagingAndSortingRepository<Register, Long> {}

我的控制器Java文件 - ＆gt; RegisterController.java

    @Controller
public class RegisterController {

    @Autowired
    RegisterRepository registerRepository;

    @RequestMapping(value="/register", method=RequestMethod.GET)
    public String form (Model model) {
        return "register/form";
    }

    @PostMapping("/register/add")
    public String registerAdd(
            @Valid Register register,
            BindingResult result,
            Model model) {
        if (result.hasErrors()) {
            return "redirect:/error";
        }
        else {

            Register r = new Register();
            r.updateRegister(register.getPseudo(), 
            register.getLastname(),
            register.getFirstname(), 
            register.getSex(),
            register.getCountry(),
            register.getPhone(),
            register.getSpokenlanguages(),
            register.getEmail(),
            register.getPassword(),
            register.getJob(),
            register.isPremium());
            System.out.println(r);

            registerRepository.save(r);

            model.addAttribute("registerlist", registerRepository.findAll());
            return "register/valid";
        }
    }

    @RequestMapping(value="/register/valid", method=RequestMethod.GET)
    public String list (Model model) {
        return "redirect:/home";
    }

}

和我的第二个HTML - ＆gt; valid.html我想先看看注册成功了...但是我在这个页面中得到了这条消息 - ＆gt; org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor和我在控制器中的试用系统会导致除了id和高级内容之外的所有内容的空值（布尔值）

提前感谢您的帮助。随意问我更多，以便更好地了解......

Answer 1

尝试在@ModelAttribute("register")方法中添加registerAdd，因此它应该是

@RequestMapping(value="/register/add", method=RequestMethod.POST)
public String registerAdd(@ModelAttribute("register") @Valid Register register, BindingResult result, Model model)

让我知道这是不是问题。

EDIT1

将此行添加到您的GET映射

model.addAttribute("register", new Register());

所以看起来应该是这样的：

@RequestMapping(value = "/register", method = RequestMethod.GET)
public String form(Model model) {
    model.addAttribute("register", new Register());
    return "register/form";
}

希望它能解决问题：）
