オブジェクト タイプ「ユーザー」をデータベースに挿入しようとしていますが、次のエラーが発生します。
org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/pages/gestionUser.jsp at line 165

例外は次のとおりです: java.lang.IllegalStateException: Bean 名 'user' の BindingResult もプレーン ターゲット オブジェクトも要求属性として使用できません
これは私のフォームです:
<form:form action="${pageContext.request.contextPath}/ajouter_user" method="post" commandName="user">

これは SimpleFormController を実装するコントローラのメソッドです
@RequestMapping(value = "/ajouter_user", method = RequestMethod.POST)
public String add(ModelMap model,Object command) {
User user = (User) command;
userservice.AddUser(user);
String msg= "Vous avez ajouter un utilisateur avec succès !";
model.addAttribute("msg_success",msg);
return "gestionUser";
}
助けてください ？間違いはどこですか？ありがとうございました
これは私のコントローラーです：
package gestion.delegation.controller;
import gestion.delegation.domaine.User;
import gestion.delegation.service.ImplIUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class GestionUserController{
private ImplIUserService userservice;
@Autowired
public void setImplserv(ImplIUserService userservice) {
this.userservice = userservice;
}
@RequestMapping(value = "/ajouter_user", method = RequestMethod.POST)
@ModelAttribute("user")
public String add(ModelMap model) {
User user = new User();
userservice.AddUser(user);
String msg= "Vous avez ajouter un utilisateur avec succès !";
model.addAttribute("msg_success",msg);
return "gestionUser";
}
}
これはクラス ユーザーです
package gestion.delegation.domaine;
public class User {
int id;
String nom;
String prenom;
String login;
String password;
String role;
boolean enable;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public boolean getEnable() {
return this.enable;
}
public void setEnable(boolean enable) {
this.enable = enable;
}
public User(int id, String
nom, String prenom, String login,
String password, String role, boolean enable) {
super();
this.id = id;
this.nom = nom;
this.prenom = prenom;
this.login = login;
this.password = password;
this.role = role;
this.enable = enable;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public User() {
super();
}
}
