我想添加一個用戶到我的數據庫,所以我創建一個驗證器的形式,但這一個不工作,當我留下一些領域空,我點擊按鈕提交什麼都沒發生我只是有這個錯誤:驗證器不工作 - 春天MVC 3
Etat HTTP 500 - Request processing failed; nested exception is org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [insert into utilisateurs (id,login, password, nom, prenom,enable) values (?,?,?,?,?,?)]; Column 'login' cannot be null; nested exception is com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Column 'login' cannot be null
這是形式:
<form:form action="${pageContext.request.contextPath}/ajouter_user" method="post" commandName="user">
<table id="tabmenu">
<tr>
<td id="idtab">Nom :</td>
<td><form:input type="text" path="nom" class="round default-width-input"/></td>
<td><form:errors path="nom" cssClass="errorbox" /></td>
</tr>
<tr>
<td id="idtab">Prénom :</td>
<td> <form:input type="text" path="prenom" class="round default-width-input"/></td>
<td><form:errors path="prenom" cssClass="errorbox" /></td>
</tr>
<tr>
<td id="idtab">Login :</td>
<td> <form:input type="text" path="login" cssClass="round default-width-input"/></td>
<td><form:errors path="login" class="errorbox" /></td>
<tr>
<td id="idtab">Password :</td>
<td> <form:input type="password" path="password" class="round default-width-input"/></td>
<td><form:errors path="password" cssClass="errorbox" /></td>
</tr>
<tr>
<td id="idtab">Séléctionner un rôle :</td>
<td> <form:select path="role">
<form:option value="" label="Selectionner" />
<form:option value="1">Administrateur</form:option>
<form:option value="2">Simple utilisateur</form:option>
</form:select></td>
<td><form:errors path="role" cssClass="errorbox" /></td>
</tr>
<tr>
<td id="idtab">Désactivé :</td>
<td><form:input type="checkbox" value="true" checked="checked" path="enable"/> Oui</td>
</tr>
<tr></tr>
<tr></tr>
<tr> <td colspan=2><input class="button round blue image-right ic-right-arrow" type="submit" value="Créer"></td></tr>
</table>
</form:form>
<div class="success"><c:out value="${msg_success}" /></div>
的驗證:
package gestion.delegation.validator;
import gestion.delegation.domaine.User;
import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;
public class AddUserValidator implements Validator{
@Override
public boolean supports(Class<?> clazz) {
return User.class.isAssignableFrom(clazz);
}
@Override
public void validate(Object obj, Errors err) {
ValidationUtils.rejectIfEmptyOrWhitespace(err, "nom", "name.required","Choisissez un nom");
ValidationUtils.rejectIfEmptyOrWhitespace(err, "prenom", "prenom.required", "Choisissez un prenom");
ValidationUtils.rejectIfEmptyOrWhitespace(err, "login", "login.required", "Choisissez un login");
ValidationUtils.rejectIfEmptyOrWhitespace(err, "password", "password.required", "Choisissez un password");
ValidationUtils.rejectIfEmpty(err, "role", "role.required", "Choisissez un role");
}
}
,這是控制器:
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.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)
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";
}
}
public void AddUser(User user) {
final String User_INSERT1 = "insert into utilisateurs (id,login, password, nom, prenom,enable) "
+ "values (?,?,?,?,?,?)";
final String User_INSERT2="insert into roles (id,login,role) values(?,?,?)";
/*
* On récupère et on utilisera directement le jdbcTemplate
*/
getJdbcTemplate()
.update(User_INSERT1,
new Object[] { user.getId(), user.getLogin(),
user.getPassword(), user.getNom(),
user.getPrenom(), user.getEnable(),
});
getJdbcTemplate().update(User_INSERT2, new Object[]{ user.getId(),user.getLogin(),user.getRole()});
}
這表明我的錯誤是在這裏:.update(User_INSERT1, 那麼,是錯在這裏?請幫忙 !謝謝
但我認爲窗體必須設置User對象的字段值? – Somar 2013-04-30 23:23:07
我解決了它是驗證器的問題,我沒有在控制器類中創建它的實例。謝謝 – Somar 2013-05-01 00:39:38
