SpringBoot Security使用MySQL实现验证与权限管理

作者：allway2

安全管理是软件系统必不可少的的功能。根据经典的“墨菲定律”——凡是可能，总会发生。如果系统存在安全隐患，最终必然会出现问题，这篇文章主要介绍了SpringBoot安全管理Spring Security基本配置

在本教程中，我将指导您如何编写代码，以使用具有基于表单的身份验证的Spring安全API来保护Spring Boot应用程序中的网页。用户详细信息存储在MySQL数据库中，并使用春季JDBC连接到数据库。我们将从本教程中的 ProductManager 项目开始，向现有的弹簧启动项目添加登录和注销功能。

1. 创建用户表和虚拟凭据

凭据应存储在数据库中，因此让我们创建新表，表间关系ER图如下：

-- --------------------------------------------------------
-- 主机:                           127.0.0.1
-- 服务器版本:                        8.0.22 - MySQL Community Server - GPL
-- 服务器操作系统:                      Win64
-- HeidiSQL 版本:                  12.1.0.6537

/*!40111 SET SQL_NOTES=IFNULL(@OLD_SQL_NOTES, 1) */;

2. 配置数据源属性

接下来，在应用程序属性文件中指定数据库连接信息，如下所示：根据您的MySQL数据库更新URL，用户名和密码。

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/product3?autoReconnect=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root
#logging.level.root=WARN

3. 声明弹簧安全性和MySQL JDBC驱动程序的依赖关系

要将Spring安全API用于项目，请在pom.xml文件中声明以下依赖项：并且要将JDBC与弹簧启动和MySQL一起使用：请注意，依赖项版本已由弹簧启动初学者父项目定义。

</project>

4. 配置 JDBC 身份验证详细信息

要将 Spring 安全性与基于表单的身份验证和 JDBC 结合使用，请按如下方式创建WebSecurityConfig类：

package com.example;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
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
    private DataSource dataSource;
    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder authBuilder) throws Exception {
        authBuilder.jdbcAuthentication()
                .dataSource(dataSource)
                .passwordEncoder(new BCryptPasswordEncoder())
                .usersByUsernameQuery("select username, password, enabled from user where username=?")
                .authoritiesByUsernameQuery("SELECT user.username,permission.name FROM user,role,user_role,permission,role_permission WHERE user.id=user_role.user_id AND role.id=user_role.role_id AND role.id=role_permission.role_id AND permission.id=role_permission.permission_id  AND user.username=?");
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/common/**").permitAll()
                .antMatchers("/login").permitAll()
                .antMatchers("/logout").permitAll()
                .antMatchers("/verify").permitAll()
                .anyRequest()
                .access("@rbacService.hasPermission(request , authentication)")
                .and()
                .formLogin().loginPage("/login")
                .permitAll()
                .and()
                .logout().permitAll()
                .and()
                .exceptionHandling().accessDeniedPage("/403");
    }
}

此安全配置类必须使用@EnableWebSecurity注释进行批注，并且是Web 安全配置器适配器的子类。数据源对象的实例将由Spring框架创建并注入：

    @Autowired
    private DataSource dataSource;

它将从应用程序属性文件中读取数据库连接信息。要使用JDBC配置身份验证，请编写以下方法：

    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder authBuilder) throws Exception {
        authBuilder.jdbcAuthentication()
                .dataSource(dataSource)
                .passwordEncoder(new BCryptPasswordEncoder())
                .usersByUsernameQuery("select username, password, enabled from users where username=?")
                .authoritiesByUsernameQuery("SELECT users.username,permissions.name FROM users,roles,users_roles,permissions,roles_permissions WHERE users.username=users_roles.username AND roles.name=users_roles.role_name AND roles.name=roles_permissions.role_name AND permissions.name=roles_permissions.permission AND users.username=?");
    }

如您所见，我们需要指定密码编码器（建议使用BCrypt），数据源和两个SQL语句：第一个根据用户名选择用户，第二个选择用户的角色。请注意，Spring安全性要求列名必须是用户名，密码，启用和角色。为了配置基于表单的身份验证，我们重写了 configure（HttpSecurity）方法，如下所示：

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/edit/*", "/delete/*").hasAnyAuthority("ADMIN")
                .anyRequest().authenticated()
                .and()
                .formLogin().permitAll()
                .and()
                .logout().permitAll()
                .and()
                .exceptionHandling().accessDeniedPage("/403");
    }

在这里，我们指定所有请求都必须进行身份验证，这意味着用户必须登录才能使用该应用程序。使用Spring安全性提供的默认登录表单。要显示已登录用户的用户名，请在Thymeleaf模板文件中编写以下代码：

<div sec:authorize="isAuthenticated()">
                Welcome <b><span sec:authentication="name">Username</span></b>
                &nbsp;
                <i><span sec:authentication="principal.authorities">Roles</span></i>
            </div>

并添加注销按钮：

            <form th:action="@{/logout}" method="post">
                <input type="submit" value="Logout" />
            </form>

如您所见，Spring Security将处理应用程序的登录和注销。我们不必编写重复的代码，只需指定一些配置即可。

5. 自定义登录验证过程

package com.example;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpSession;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import static org.springframework.security.web.context.HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY;
@Controller
public class LoginController {
    /**
     * 注入身份认证管理器
     */
    @Autowired
    private AuthenticationManager authenticationManager;
    @GetMapping("/login")
    public String login() {
        return "login";
    }
    @PostMapping(value = "/verify")
    public String login(@RequestParam("username") String username,
            @RequestParam("password") String password,
            @RequestParam("verifyCode") String verifyCode,
            HttpSession session) {
        System.out.println("username is:" + username);
        System.out.println("password is:" + password);
        System.out.println("verifyCode is:" + verifyCode);
        if (StringUtils.isEmpty(verifyCode)) {
            session.setAttribute("errorMsg", "The verification code cannot be empty");
            return "login";
        }
        if (StringUtils.isEmpty(username) || StringUtils.isEmpty(password)) {
            session.setAttribute("errorMsg", "User name or password cannot be empty");
            return "login";
        }
        String kaptchaCode = session.getAttribute("verifyCode") + "";
        System.out.println("kaptchaCode is:" + kaptchaCode);
        if (StringUtils.isEmpty(kaptchaCode) || !verifyCode.equals(kaptchaCode)) {
            session.setAttribute("errorMsg", "Verification code error");
            return "login";
        }
//        User user = userService.login(userName, password);
        System.out.println(username + "==" + password + "==" + verifyCode);
        // 创建用户名与密码认证对象
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
        try {
            // 调用认证方法，返回认证对象
            Authentication authenticate = authenticationManager.authenticate(token);
            // 判断是否认证成功
            if (authenticate.isAuthenticated()) {
                // 设置用户认证成功，往Session中添加认证通过信息
                SecurityContextHolder.getContext().setAuthentication(authenticate);
                SecurityContext sc = SecurityContextHolder.getContext();
                sc.setAuthentication(authenticate);
                session.setAttribute(SPRING_SECURITY_CONTEXT_KEY, sc);
                // 重定向到登录成功页面
                return "redirect:/";
            } else {
                session.setAttribute("errorMsg", "Login failed");
                return "login";
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return "login";
    }
}

7. 测试登录和注销

启动Spring Boot应用程序并访问 http://localhost:8080 在Web浏览器中，您将看到自定义的登录页面出现：

现在输入正确的用户名admin和密码admin，您将看到主页如下：

并注意欢迎消息后跟用户名。用户现在已通过身份验证以使用该应用程序。单击“注销”按钮，您将看到自定义的登录页面出现，这意味着我们已成功实现登录并注销到我们的Spring Boot应用程序。

自定义从数据库中获取动态权限验证

package com.example;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import lombok.Data;
@Data
@Entity
public class Permission {
    @Id
    private Long id;
    private String name;
    private String description;
    private String uri;
    private String method;
}
package com.example;
import org.springframework.data.jpa.repository.JpaRepository;
public interface PermissionRepository extends JpaRepository<Permission, Long> {
    public Permission findByName(String name);
}
package com.example;
import javax.servlet.http.HttpServletRequest;
import org.springframework.security.core.Authentication;
/**
 * RBAC模型实现Security,即通过角色对用户进行分组，在对每个角色进行权限授权就， 进而简化用户权限分配以及管理。 需要的表： user：
 * 用户信息表 保存有的用户id,用户名、密码、账号、状态、salt加盐 role:角色表 user_role:用户角色关联表 permission： 权限表
 * 保存的有权限相关信息 role_permission: 角色与权限管理表
 */
public interface RbacService {
    //用户判断当前请求是否有操作权限
    boolean hasPermission(HttpServletRequest request, Authentication authentication);
}

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

        Object principal = authentication.getPrincipal();
        System.out.println(principal.getClass());
        //判断数据是否为空 以及类型是否正确
        if (null != principal && principal instanceof User) {
            String username = ((User) principal).getUsername();
            System.out.println(username);
        }
        String requestURI = request.getRequestURI();
        System.out.println(requestURI);
        String method = request.getMethod();
        System.out.println(method);
        Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
        boolean hasPermission = false;
        for (GrantedAuthority authority : authorities) {
            String authorityname = authority.getAuthority();
            System.out.println(authority.getAuthority());
            Permission permission = permissionRepository.findByName(authorityname);
            System.out.println(permissionRepository.findByName(authorityname));
            if (null != permission && permission.getMethod().equals(request.getMethod()) && antPathMatcher.match(permission.getUri(), request.getRequestURI())) {
                hasPermission = true;
                break;
            }
        }
        System.out.println(hasPermission);
