本篇文章来看看基于角色的权限控制 —— RBAC(Role-Based Access Control），就是用户通过角色与权限进行关联。简单地说，一个用户拥有若干角色，每一个角色拥有若干权限。这样就构造成了『用户-角色-权限』的授权模型。在这种模型中，用户与角色之间，角色与权限之间，一般是多对多的关系。理解了 RBAC 之后，再通过Spring Security oAuth2来实现基于 RBAC 的自定义认证。

RBAC概述

RBAC 认为授权实际上是Who 、What 、How 三元组之间的关系，也就是 Who 对 What 进行 How 的操作，也就是『主体』对『客体』的操作。 Who：是权限的拥有者或主体（如：User、Role）。 What：是操作或对象（operation、object）。 How：具体的权限（Privilege，正向授权与负向授权）

在我们的 oAuth2 系统中，我们需要对系统的所有资源进行权限控制，系统中的资源包括： 1、静态资源（对象资源）：功能操作、数据列 2、动态资源（数据资源）：文章、相册、笔记

系统的目的就是对应用系统的所有对象资源和数据资源进行权限控制，比如：功能菜单、界面按钮、数据显示的列、各种行级数据进行权限的操控。

创建数据表

所以根据上面的定义，我们至少需要五张表： ① user 用户表、② role 角色表、③ permission 权限表、④ user_role 用户-角色表、⑤ role_permission 角色-权限表

对应的SQL如下：

CREATE TABLE `tb_permission`
(
    `id`          bigint(20)   NOT NULL AUTO_INCREMENT,
    `parent_id`   bigint(20)   DEFAULT NULL COMMENT '父权限',
    `name`        varchar(64)  NOT NULL COMMENT '权限名称',
    `enname`      varchar(64)  NOT NULL COMMENT '权限英文名称',
    `url`         varchar(255) NOT NULL COMMENT '授权路径',
    `description` varchar(200) DEFAULT NULL COMMENT '备注',
    `created`     datetime     NOT NULL,
    `updated`     datetime     NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 37
  DEFAULT CHARSET = utf8 COMMENT ='权限表';

CREATE TABLE `tb_role`
(
    `id`          bigint(20)  NOT NULL AUTO_INCREMENT,
    `parent_id`   bigint(20)   DEFAULT NULL COMMENT '父角色',
    `name`        varchar(64) NOT NULL COMMENT '角色名称',
    `enname`      varchar(64) NOT NULL COMMENT '角色英文名称',
    `description` varchar(200) DEFAULT NULL COMMENT '备注',
    `created`     datetime    NOT NULL,
    `updated`     datetime    NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 37
  DEFAULT CHARSET = utf8 COMMENT ='角色表';

CREATE TABLE `tb_role_permission`
(
    `id`            bigint(20) NOT NULL AUTO_INCREMENT,
    `role_id`       bigint(20) NOT NULL COMMENT '角色 ID',
    `permission_id` bigint(20) NOT NULL COMMENT '权限 ID',
    PRIMARY KEY (`id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 37
  DEFAULT CHARSET = utf8 COMMENT ='角色权限表';

CREATE TABLE `tb_user`
(
    `id`       bigint(20)  NOT NULL AUTO_INCREMENT,
    `username` varchar(50) NOT NULL COMMENT '用户名',
    `password` varchar(64) NOT NULL COMMENT '密码，加密存储',
    `phone`    varchar(20) DEFAULT NULL COMMENT '注册手机号',
    `email`    varchar(50) DEFAULT NULL COMMENT '注册邮箱',
    `created`  datetime    NOT NULL,
    `updated`  datetime    NOT NULL,
    PRIMARY KEY (`id`),
    UNIQUE KEY `username` (`username`) USING BTREE,
    UNIQUE KEY `phone` (`phone`) USING BTREE,
    UNIQUE KEY `email` (`email`) USING BTREE
) ENGINE = InnoDB
  AUTO_INCREMENT = 37
  DEFAULT CHARSET = utf8 COMMENT ='用户表';

CREATE TABLE `tb_user_role`
(
    `id`      bigint(20) NOT NULL AUTO_INCREMENT,
    `user_id` bigint(20) NOT NULL COMMENT '用户 ID',
    `role_id` bigint(20) NOT NULL COMMENT '角色 ID',
    PRIMARY KEY (`id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 37
  DEFAULT CHARSET = utf8 COMMENT ='用户角色表';

代码实现

为了对许多拥有相似权限的用户进行分类管理，定义了角色的概念，例如系统管理员、管理员、用户、访客等角色。角色具有上下级关系，可以形成树状视图，父级角色的权限是自身及它的所有子角色的权限的综合。父级角色的用户、父级角色的组同理可推。

认证授权服务器配置

对于spring-security-oauth2-server（认证授权服务器）,资源服务器需要访问 /oauth/check_token 端点来检查 access_token 的有效性，此时该端点是受保护的资源，当我们访问该端点时会遇到 403 问题，将该端点暴露出来即可，暴露端点的关键代码为，WebSecurityConfiguration.java：

@Override
public void configure(WebSecurity web) {
    web.ignoring().antMatchers("/oauth/check_token");
}

之前介绍过资源的概念，简单点说就是需要被访问的业务数据或是静态资源文件都可以被称作资源。现在单独创建一个名为 spring-security-oauth2-resource 资源服务器的项目，该项目的主要目的就是对数据表的 CRUD 操作，而这些操作就是对资源的操作了，但是为了方便只需要使用两个简单的示例即可，该项目的 pom.xml 如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>cn.tim.security.resources.OAuth2ResourceApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

该项目的唯一一个 Controller 也比较简单

@RestController
@RequestMapping("/users")
public class UserController {

    @GetMapping
    public String index(){
        return "{\n" +
                "    \"people\":[\n" +
                "        {\n" +
                "            \"firstName\":\"Brett\",\n" +
                "            \"lastName\":\"McLaughlin\"\n" +
                "        },\n" +
                "        {\n" +
                "            \"firstName\":\"Jason\",\n" +
                "            \"lastName\":\"Hunter\"\n" +
                "        }\n" +
                "    ]\n" +
                "}";
    }
}

资源服务器配置

接下来需要配置资源服务器，创建一个类继承 ResourceServerConfigurerAdapter 并添加相关注解，这个配置类我起名为ResourceServerConfiguration：

package cn.tim.security.resources.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

@Configuration
@EnableResourceServer
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/users").hasAuthority("SystemUser")
                .antMatchers("/contents").hasAuthority("SystemContent")
                .antMatchers("/contents/view/**").hasAuthority("SystemContentView");
    }
}

application.yml

spring:
  application:
    name: resource-server-1
server:
  port: 8090
  servlet:
    context-path: /

# 配置的就是认证服务器的认证地址
security:
  oauth2:
    client:
      client-id: client
      client-secret: secret
      access-token-uri: http://localhost:8080/oauth/token
      user-authorization-uri: http://localhost:8080/oauth/authorize
    resource:
      token-info-uri: http://localhost:8080/oauth/check_token

logging:
  level:
    root: INFO
    org.springframework.web: INFO
    org.springframework.security: INFO
    org.springframework.security.oauth2: INFO

资源服务器需要访问 /oauth/check_token 端点来检查 access_token 的有效性，此时该端点是受保护的资源，当我们访问该端点时会遇到 403 问题，将该端点暴露出来即可，暴露端点的关键代码是在spring-security-oauth2-server的 WebSecurityConfiguration 中：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    @Override
    public UserDetailsService userDetailsService() {
        return new UserDetailsServiceImpl();
    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService());
    }

    @Override
    public void configure(WebSecurity web) {
      // 将 check_token 暴露出去，否则资源服务器访问时报 403 错误
        web.ignoring().antMatchers("/oauth/check_token");
    }
}

示例项目验证

整个示例项目就完成了，下面还是以前的步骤，先访问获取授权码打开浏览器，输入地址：

GET http://localhost:8080/oauth/authorize?client_id=tencent&response_type=code

登录成功后会询问用户是否授权客户端: 然后拿到授权码code，根据code再请求 access_token:

POST http://tencent:secret@localhost:8080/oauth/token

然后再根据 access_token 直接去调用接口就好了：由于整个工程模块比较多，说起来也比较杂乱，索性直接上传到Github， https://github.com/zouchanglin/spring-security-oauth2

最后，有没有发现我们已经实现了SSO了呢？其实单点登录就这么简单呀!
