  • ORACLE:
-- Create table
create table USERS
(
  USERNAME VARCHAR2(36) not null,
  PASSWORD VARCHAR2(36) not null,
  ENABLED  NUMBER(1) not null
) ;

alter table USERS
  add constraint USER_PK primary key (USERNAME);

---------------------

-- Create table
create table USER_ROLES
(
  ROLE_ID   VARCHAR2(50) not null,
  USERNAME  VARCHAR2(36) not null,
  USER_ROLE VARCHAR2(30) not null
) ;
 
alter table USER_ROLES
  add constraint USER_ROLE_PK primary key (ROLE_ID);

alter table USER_ROLES
  add constraint USER_ROLE_UK unique (USERNAME, USER_ROLE);
 
-------------------------------
 
insert into users (USERNAME, PASSWORD, ENABLED)
values ('dbuser1', '12345', 1);

insert into users (USERNAME, PASSWORD, ENABLED)
values ('dbadmin1', '12345', 1);  


insert into User_Roles (ROLE_ID, USERNAME, USER_ROLE)
values ('1', 'dbuser1', 'USER');

insert into User_Roles (ROLE_ID, USERNAME, USER_ROLE)
values ('2', 'dbadmin1', 'ADMIN');

insert into User_Roles (ROLE_ID, USERNAME, USER_ROLE)
values ('3', 'dbadmin1', 'USER');

6- Configuration Spring MVC & Security

SpringWebAppInitializer.java
package org.o7planning.springmvcsecurity.config;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.web.WebApplicationInitializer;

public class SpringWebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
        appContext.register(ApplicationContextConfig.class);

        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher",
                new DispatcherServlet(appContext));
        dispatcher.setLoadOnStartup(1);

7- Les classes participées en sécurité (Security)

La classe  UserInfo est équivalent au tableau  USERS dans la base de données.
UserInfo.java
package org.o7planning.springmvcsecurity.model;

public class UserInfo {

    private String userName;
    private String password;
    
    public UserInfo()  {
        
    }

    public UserInfo(String userName, String password) {
        this.userName = userName;
        this.password = password;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}
La classe  UserInfoMapper sert à mapper les colonnes de l'instruction SQL correspondant aux champs (field) de UserInfo.
UserInfoMapper.java
package org.o7planning.springmvcsecurity.mapper;

import java.sql.ResultSet;
import java.sql.SQLException;

import org.o7planning.springmvcsecurity.model.UserInfo;
import org.springframework.jdbc.core.RowMapper;

public class UserInfoMapper implements RowMapper<UserInfo> {

    @Override
    public UserInfo mapRow(ResultSet rs, int rowNum) throws SQLException {

        String userName = rs.getString("Username");
        String password = rs.getString("Password");

        return new UserInfo(userName, password);
    }

}
UserInfoDAO.java
package org.o7planning.springmvcsecurity.dao;

import java.util.List;

import org.o7planning.springmvcsecurity.model.UserInfo;

public interface UserInfoDAO {
    
    public UserInfo findUserInfo(String userName);
    
    // [USER,AMIN,..]
    public List<String> getUserRoles(String userName);
    
}
UserInfoDAOImpl.java
package org.o7planning.springmvcsecurity.dao.impl;

import java.util.List;

import javax.sql.DataSource;

import org.o7planning.springmvcsecurity.dao.UserInfoDAO;
import org.o7planning.springmvcsecurity.mapper.UserInfoMapper;
import org.o7planning.springmvcsecurity.model.UserInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.EmptyResultDataAccessException;
import org.springframework.jdbc.core.support.JdbcDaoSupport;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class UserInfoDAOImpl extends JdbcDaoSupport implements UserInfoDAO {

    @Autowired
    public UserInfoDAOImpl(DataSource dataSource) {
        this.setDataSource(dataSource);
    }
 

    @Override
    public UserInfo findUserInfo(String userName) {
        String sql = "Select u.Username,u.Password "//
                + " from Users u where u.Username = ? ";

        Object[] params = new Object[] { userName };
        UserInfoMapper mapper = new UserInfoMapper();
        try {
            UserInfo userInfo = this.getJdbcTemplate().queryForObject(sql, params, mapper);
            return userInfo;
        } catch (EmptyResultDataAccessException e) {
            return null;
        }
    }


    @Override
    public List<String> getUserRoles(String userName) {
        String sql = "Select r.User_Role "//
                + " from User_Roles r where r.Username = ? ";
        
        Object[] params = new Object[] { userName };
        
        List<String> roles = this.getJdbcTemplate().queryForList(sql,params, String.class);
        
        return roles;
    }
    
}
La classe  MyDBAuthenticationService sert à personnaliser l'authentification, elle implémente l'interface AuthenticationService.
MyDBAuthenticationService.java
package org.o7planning.springmvcsecurity.authentication;

import java.util.ArrayList;
import java.util.List;

import org.o7planning.springmvcsecurity.dao.UserInfoDAO;
import org.o7planning.springmvcsecurity.model.UserInfo;

import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

@Service
public class MyDBAuthenticationService implements UserDetailsService {

    @Autowired
    private UserInfoDAO userInfoDAO;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserInfo userInfo = userInfoDAO.findUserInfo(username);
        System.out.println("UserInfo= " + userInfo);

        if (userInfo == null) {
            throw new UsernameNotFoundException("User " + username + " was not found in the database");
        }
        
        // [USER,ADMIN,..]
        List<String> roles= userInfoDAO.getUserRoles(username);
        
        List<GrantedAuthority> grantList= new ArrayList<GrantedAuthority>();
        if(roles!= null)  {
            for(String role: roles)  {
                // ROLE_USER, ROLE_ADMIN,..
                GrantedAuthority authority = new SimpleGrantedAuthority("ROLE_" + role);
                grantList.add(authority);

8- Spring MVC Controller

MainController.java
package org.o7planning.springmvcsecurity.controller;

import java.security.Principal;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class MainController {

   @RequestMapping(value = { "/", "/welcome" }, method = RequestMethod.GET)
   public String welcomePage(Model model) {
       model.addAttribute("title", "Welcome");
       model.addAttribute("message", "This is welcome page!");
       return "welcomePage";
   }

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

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

   @RequestMapping(value = "/logoutSuccessful", method = RequestMethod.GET)
   public String logoutSuccessfulPage(Model model) {
       model.addAttribute("title", "Logout");
       return "logoutSuccessfulPage";
   }

   @RequestMapping(value = "/userInfo", method = RequestMethod.GET)
   public String userInfo(Model model, Principal principal) {

       // After user login successfully.
       String userName = principal.getName();

       System.out.println("User Name: "+ userName);

       return "userInfoPage";
   }

   @RequestMapping(value = "/403", method = RequestMethod.GET)
   public String accessDenied(Model model, Principal principal) {
       
       if (principal != null) {
           model.addAttribute("message", "Hi " + principal.getName()
                   + "<br> You do not have permission to access this page!");
       } else {
           model.addAttribute("msg",
                   "You do not have permission to access this page!");
       }
       return "403Page";
   }
}

10- Configurer et exécuter l'application

Tout d'abord, avant d'exécuter l'application, vous devez  build le projet.
Cliquez sur le bouton droit du projet et sélectionnez :
  • Run As/Maven install

Exécutez des configurations :

Saisissez :
  • Name: Run SpringMVCSecurity
  • Base directory: ${workspace_loc:/SpringMVCAnnotationSecurity}
  • Goals: tomcat7:run
Exécutez URL:
Saisissez l'URL pour voir les informations de l'utilisateur, au cas où vous ne vous connectez pas, le site web sera redirigé vers la page de connexion
Si vous saisissez informations erronées et cliquez sur Submit, le site Web redirigera vers la page de connexion.
Dans le cas d'une connexion réussie :
Vous pouvez essayer avec le lien.
Le chemin ci-dessus permet seulement à l'utilisateur jouant le rôle ADMIN (ROLE_ADMIN) d'accéder:

Dans le cas où vous ne vous êtes pas connecté, le site web redirigera vers la page de connexion. Si vous vous connectez en tant que ROLE_USER, vous recevrez un message "Accès refusé" (Access Denied).

11- Fix Error!

Remarque, si vous recevez l'erreur :
HTTP Status 404 - /SpringMVCAnnotationSecurity/j_spring_security_check
Assurez- vous que votre application contient la classe SpringSecurityInitializer:
SpringSecurityInitializer.java
package org.o7planning.springmvcsecurity.config;

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;


public class SpringSecurityInitializer extends AbstractSecurityWebApplicationInitializer {

    // Do nothing

}
