1. Цель примера

Статья основана на:
  • Spring Boot 2.x

  • Spring Security

  • Spring JDBC

  • Thymeleaf

  • Database: MySQL, SQL Server, Oracle, Postgres

В данной статье я покажу вам как создать приложение Login, используя Spring Boot + Spring Security + JDBC + Thymeleaf. И объясню принцип работы Spring Security.
Пользователь обязан войти в систему, чтобы просмотреть защищенные страницы:
Пользователи, которые вошеи в систему могут просмотреть страницы только в рамках их роли. Если они будут просматривать страницы вне их роли, доступ будет отказан.

2. Приготовить базу данных

MySQL
-- Create table
create table APP_USER
(
  USER_ID           BIGINT not null,
  USER_NAME         VARCHAR(36) not null,
  ENCRYTED_PASSWORD VARCHAR(128) not null,
  ENABLED           BIT not null  
) ;
--  
alter table APP_USER
  add constraint APP_USER_PK primary key (USER_ID);

alter table APP_USER
  add constraint APP_USER_UK unique (USER_NAME);


-- Create table
create table APP_ROLE
(
  ROLE_ID   BIGINT not null,
  ROLE_NAME VARCHAR(30) not null
) ;
--  
alter table APP_ROLE
  add constraint APP_ROLE_PK primary key (ROLE_ID);

alter table APP_ROLE
  add constraint APP_ROLE_UK unique (ROLE_NAME);


-- Create table

  references APP_USER (USER_ID);

alter table USER_ROLE
  add constraint USER_ROLE_FK2 foreign key (ROLE_ID)
  references APP_ROLE (ROLE_ID);

3. Создать Spring Boot Project

На Eclipse создать проект Spring Boot.
Ввести:
  • Name: SbSecurityJdbcThymeleaf
  • Group: org.o7planning
  • Artifact: SbSecurityJdbcThymeleaf
  • Description: Spring Boot + JDBC + Security + Thymeleaf
  • Package: org.o7planning.sbsecurity
Следующий шаг, вам нужно выбрать технологии и библиотеки которые будут использованы ( В данной статье мы подключимся к базе данных Oracle, MySQL, SQL Server или Postgres).
Database Libraries:
  • MySQL
  • PostgresSQL
  • SQL Server
Tech:
  • Web
  • Thymeleaf
  • Security
OK Project создан.
SbSecurityJdbcThymeleafApplication.java
package org.o7planning.sbsecurity;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SbSecurityJdbcThymeleafApplication {

    public static void main(String[] args) {
        SpringApplication.run(SbSecurityJdbcThymeleafApplication.class, args);
    }
}

4. Конфигурация pom.xml

Если вы используете базу данных Oracle, вам нужно объявить нужную библиотеку для Oracle в файле pom.xml:
** Oracle **
<dependencies>
    .....

     <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0.3</version>
    </dependency>
    
    .....
</dependencies>

<repositories>
        ....

    <!-- Repository for ORACLE JDBC Driver -->
    <repository>
        <id>codelds</id>
        <url>https://code.lds.org/nexus/content/groups/main-repo</url>
    </repository>
    
    .....
</repositories>
Если вы подключаете к базе данных SQL Service, вы можете использовать одну из 2 библиотек JTDS или Mssql-Jdbc:
** SQL Server **
<dependencies>
       .....

    <dependency>
        <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>mssql-jdbc</artifactId>
        <scope>runtime</scope>
    </dependency>
    
    <dependency>
        <groupId>net.sourceforge.jtds</groupId>
        <artifactId>jtds</artifactId>
        <scope>runtime</scope>
    </dependency>

    </repositories>

</project>

5. Конфигурация Datasource

Чтобы Spring подключился к базе данныхвам нужно конфигурировать необходимые параметрыв файле application.properties.
application.properties (ORACLE)
# Database Connection

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:db12c
spring.datasource.username=Test
spring.datasource.password=test001

# Other properties ..
application.properties (SQL Server + JTDS driver)
# Database Connection

spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver
spring.datasource.url=jdbc:jtds:sqlserver://localhost:1433/simplehr;instance=SQLEXPRESS
spring.datasource.username=sa
spring.datasource.password=12345

# Other properties ..
application.properties (SQL Server + Mssql-jdbc Driver)
# Database Connection

spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://tran-vmware-pc\\SQLEXPRESS:1433;databaseName=Test
spring.datasource.username=sa
spring.datasource.password=12345

# Other properties ..
application.properties (MySQL)
# Database Connection

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=root
spring.datasource.password=12345

# Other properties ..
application.properties (Postgres)
# Database Connection

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/mydatabase
spring.datasource.username=postgres
spring.datasource.password=12345

# Other properties ..

6. Конфигурация защиты

Данное приложение имеет некоторые функции (страницы), которые:
  • /userInfo
Это страница просмотра информации пользователя, данная страница требует пользователя войти в систему, и имет роль ROLE_ADMIN или ROLE_USER.
  • /admin
Это страница для администратора, требует пользователя войти в систему, и только люди с ролем ROLE_ADMIN имеют право на доступ.
  • /. /welcome, /login, /logout, /403
Все другие страницы в приложении не требуют пользователя входить в систему.
Класс WebSecurityConfig используется для конфигурации защиты для приложения. Он аннотирован (annotate) с помощью @Configuration, Данная аннотация говорит Spring что он является классом конфигурации, поэтому он будет анализирован с помощью Spring во время запуска данного приложения.
WebSecurityConfig.java
package org.o7planning.sbsecurity.config;

import org.o7planning.sbsecurity.service.UserDetailsServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

	@Autowired
	UserDetailsServiceImpl userDetailsService;

	@Bean
	public BCryptPasswordEncoder passwordEncoder() {
		BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
		return bCryptPasswordEncoder;
	}
	
	
	@Autowired
	public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 

		// Setting Service to find User in the database.
		// And Setting PassswordEncoder
		auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());		

	}

	@Override
	protected void configure(HttpSecurity http) throws Exception {

		http.csrf().disable();

		// The pages does not require login
		http.authorizeRequests().antMatchers("/", "/login", "/logout").permitAll();

		// /userInfo page requires login as ROLE_USER or ROLE_ADMIN.
		// If no login, it will redirect to /login page.
		http.authorizeRequests().antMatchers("/userInfo").access("hasAnyRole('ROLE_USER', 'ROLE_ADMIN')");

		// For ADMIN only.
		http.authorizeRequests().antMatchers("/admin").access("hasRole('ROLE_ADMIN')");

		// When the user has logged in as XX.
		// But access a page that requires role YY,
		// AccessDeniedException will be thrown.
		http.authorizeRequests().and().exceptionHandling().accessDeniedPage("/403");

		// Config for Login Form
		http.authorizeRequests().and().formLogin()//
				// Submit URL of login page.
				.loginProcessingUrl("/j_spring_security_check") // Submit URL
				.loginPage("/login")//
				.defaultSuccessUrl("/userAccountInfo")//
				.failureUrl("/login?error=true")//
				.usernameParameter("username")//
				.passwordParameter("password")
				// Config for Logout Page
				.and().logout().logoutUrl("/logout").logoutSuccessUrl("/logoutSuccessful");

	}
}

7. Model, Mapper, DAO, WebUtils

Класс AppUser представляет запись в таблице APP_USER базы данных.
AppUser.java
package org.o7planning.sbsecurity.model;

public class AppUser {

    private Long userId;
    private String userName;
    private String encrytedPassword;

    public AppUser() {

    }

    public AppUser(Long userId, String userName, String encrytedPassword) {
        this.userId = userId;
        this.userName = userName;
        this.encrytedPassword = encrytedPassword;
    }

    public Long getUserId() {
        return userId;
    }

    public void setUserId(Long userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

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

    public String getEncrytedPassword() {
        return encrytedPassword;
    }

    public void setEncrytedPassword(String encrytedPassword) {
        this.encrytedPassword = encrytedPassword;
    }

    @Override
    public String toString() {
        return this.userName + "/" + this.encrytedPassword;
    }

}
Класс AppUserMapper используется для сопоставления (mapping) столбцов в таблице APP_USER с полями (field) в классе AppUser (Основывая на команде запроса).
AppUserMapper.java
package org.o7planning.sbsecurity.mapper;

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

import org.o7planning.sbsecurity.model.AppUser;

Классы DAO (Data Access Object) являются классами использующиеся для доступа в базу данных, например Query, Insert, Update, Delete. Классы DAO обычно аннотированыы с помощью @Repository чтобы сказать Spring управлять ими как Spring BEAN.
Класс AppUserDAO используется для манипуляции с таблицей APP_USER. Он имеет метод поиска пользователя в базе данных соответствующего имени пользователя.
AppUserDAO.java
package org.o7planning.sbsecurity.dao;

import javax.sql.DataSource;

import org.o7planning.sbsecurity.mapper.AppUserMapper;

package org.o7planning.sbsecurity.utils;

import java.util.Collection;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.User;

public class WebUtils {

    public static String toString(User user) {
        StringBuilder sb = new StringBuilder();

        sb.append("UserName:").append(user.getUsername());

        Collection<GrantedAuthority> authorities = user.getAuthorities();

8. UserDetailsService

UserDetailsService это центральный интерфейс в Spring Security. Это сервис для поиска "Аккаунт пользователя и роли того пользователя". Используется Spring Security каждый раз, когда пользователь входит в систему. Поэтому вам нужно написать класс применения (implements) данного интерфейса.
Здесь я создаю класс UserDetailsServiceImpl применения (implements) интерфейса UserDetailsService. Класс UserDetailsServiceImpl аннотирован с помощью @Service чтобы сказать Spring управлять им как Spring BEAN.
UserDetailsServiceImpl.java
package org.o7planning.sbsecurity.service;

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

import org.o7planning.sbsecurity.dao.AppUserDAO;
import org.o7planning.sbsecurity.dao.AppRoleDAO;
import org.o7planning.sbsecurity.model.AppUser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
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 UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private AppUserDAO appUserDAO;

    @Autowired
    private AppRoleDAO appRoleDAO;

    @Override
    public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
        AppUser appUser = this.appUserDAO.findUserAccount(userName);

        if (appUser == null) {
            System.out.println("User not found! " + userName);
            throw new UsernameNotFoundException("User " + userName + " was not found in the database");
        }

        System.out.println("Found User: " + appUser);

        // [ROLE_USER, ROLE_ADMIN,..]
        List<String> roleNames = this.appRoleDAO.getRoleNames(appUser.getUserId());

        List<GrantedAuthority> grantList = new ArrayList<GrantedAuthority>();
        if (roleNames != null) {
            for (String role : roleNames) {
                // ROLE_USER, ROLE_ADMIN,..
                GrantedAuthority authority = new SimpleGrantedAuthority(role);
                grantList.add(authority);
            }
        }

        UserDetails userDetails = (UserDetails) new User(appUser.getUserName(), //
                appUser.getEncrytedPassword(), grantList);

        return userDetails;
    }

}

9. Controllers

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

import java.security.Principal;

import org.o7planning.sbsecurity.utils.WebUtils;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.userdetails.User;
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, Principal principal) {
        
        User loginedUser = (User) ((Authentication) principal).getPrincipal();

        String userInfo = WebUtils.toString(loginedUser);
        model.addAttribute("userInfo", userInfo);
        
        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) {

        // (1) (en)
        // After user login successfully.
        // (vi)
        // Sau khi user login thanh cong se co principal
        String userName = principal.getName();

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

        User loginedUser = (User) ((Authentication) principal).getPrincipal();

        String userInfo = WebUtils.toString(loginedUser);
        model.addAttribute("userInfo", userInfo);

        return "userInfoPage";
    }

    @RequestMapping(value = "/403", method = RequestMethod.GET)
    public String accessDenied(Model model, Principal principal) {

        if (principal != null) {
            User loginedUser = (User) ((Authentication) principal).getPrincipal();

            String userInfo = WebUtils.toString(loginedUser);

            model.addAttribute("userInfo", userInfo);

            String message = "Hi " + principal.getName() //
                    + "<br> You do not have permission to access this page!";
            model.addAttribute("message", message);

        }

        return "403Page";
    }

}

10. Thymeleaf Template

_menu.html используется как часть веб страницы, он погружен в другие страницы, чтобы создать Menu страницы.
