### 五、自定义认证数据源 ###

> 认证流程分析

**官方文档**：[https://docs.spring.io/spring-security/site/docs/5.5.8/reference/html5/\#servlet-authentication-abstractprocessingfilter][https_docs.spring.io_spring-security_site_docs_5.5.8_reference_html5_servlet-authentication-abstractprocessingfilter]

*  发起认证请求，请求中携带用户名、密码，该请求会被`UsernamePasswordAuthenticationFilter`拦截
 *  在`UsernamePasswordAuthenticationFilter`的 **attemptAuthentication** 方法中将请求中的用户名和密码，封装为 **Authentication** 对象，并交给 **AuthenticationManager** 进行认证
 *  认证成功，将认证信息存储到 **SecurityContextHolder** 以及调用记住我信息，并回调 **AuthenticationSuccessHandler** 处理
 *  认证失败，清除 **SecurityContextHolder** 以及记住我中的信息，回调 **AuthenticationFailureHandler** 处理

> AuthenticationManager、ProviderManager、AuthenticationProvider 三者关系

AuthenticationManager 是认证的核心类，但实际上在底层真正认证时还离不开 ProviderManager 以及 AuthenticationProvider

*  `AuthenticationManager`是一个认证管理器，它定义了 SpringSecurity 过滤器要执行认证操作
 *  `ProviderManager` 是 **AuthenticationManager** 接口的实现类。SpringSecurity 认证时默认使用就是 ProviderManager
 *  `AuthenticationProvider`就是针对不同的身份类型执行的具体身份认证

**AuthenticationManager 与 ProviderManager**

**ProviderManager** 是 **AuthenticationManager** 的唯一实现，也是 SpringSecurity 默认使用实现。不难看出默认情况下 AuthenticationManager 就是一个 ProviderManager

> ProviderManager 与 AuthenticationProvider

**官方文档**：[https://docs.spring.io/spring-security/site/docs/5.5.8/reference/html5/\#servlet-authentication-providermanager][https_docs.spring.io_spring-security_site_docs_5.5.8_reference_html5_servlet-authentication-providermanager]

![在这里插入图片描述][2f58559cc0fa4c8ca69352c178a392fe.png_pic_center]

*  在 SpringSecurity 中，允许系统同时支持多种不同的认证方式，例如同时支持用户名/密码认证、ReremberMe 认证、手机号码动态认证等，而不同的认证方式对应了不同的 AuthenticationProvider，所以一个完整的认证流程可能由多个 AuthenticationProvider 来提供
 *  多个 AuthenticationProvider 将组成一个列表，这个列表将由 ProviderManager 代理。换句话说，**在 ProviderManager 中存在一个 AuthenticationProvider 列表，在 ProviderManager 中遍历列表中的每一个 AuthenticationProvider 去执行身份认证，最终得到认证结果**
 *  ProviderManager 本身也可以再配置一个 AuthenticationManager 作为 parent，这样当 ProviderManager 认证失败之后，就可以进入到 parent 中再次进行认证。理论上来说， **ProviderManager 的 parent 可以是任意类型的 AuthenticationManager，但是通常都是由 ProviderManager 来扮演 parent 的角色，也就是 ProviderManager 是 ProviderManager 的 parent**（源码分析得出）
 *  ProviderManager 本身也可以有多个，多个 ProviderManager 共用同一个 parent。有时，一个应用程序有受保护资源的逻辑组例如，所有符合路径模式的网络资源，如/api/\*\*)，每个组可以有自己的专用 AuthenticationManager。通常，每个组都是一个 ProviderManager，它们共享一个父级。然后，父级是一种`全局`资源，作为所有提供者的后备资源

根据上面的介绍，我们绘出新的 AuthenticationManager、ProvideManager 和 AuthentictionProvider 关系（责任链模式）

#### 5.2 自定义认证数据源之原理分析（二） ####

认证时，首先经过局部的 ProviderManager（子），后 ProviderManager（父）

默认情况下，AuthenticationManager 是由 **DaoAuthenticationProvider** 类实现认证的，在 **DaoAuthenticationProvider** 认证时，又通过 **UserDetailsService** 完成数据源的校验

*  **它们之间的调用关系如下**

![在这里插入图片描述][805c8dffeb70448291d6b33b74f44405.png_pic_center]

*  **总结**

**AuthenticationManager** 是认证管理器 ，**在 SpringSecurity 中有全局 AuthenticationManager，也可以有局部 AuthenticationManager**。全局的 AuthenticationManager 用来对全局认证进行处理，局部的 AuthenticationManager 用来对某些特殊资源认证处理。无论是全局认证管理器还是局部认证管理器都是由 ProviderManager 进行实现。*每一个 ProviderManager 中都代理一个 AuthenticationProvider 的列表，列表中每一个实现代表一种身份认证方式*。认证时底层数据源需要调用 **UserDetailsService** 实现

     *  重写 WebSecurityConfigurerAdapter 类使得默认 DefaultWebSecurityCondition 条件失效
     */
    @Configuration
    public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
        
    
        // 在之前查看源码中发现,当发现有 UserDetailsService.class 这个bean的时候, UserDetailsServiceAutoConfiguration 就会失效
        @Bean
        public UserDetailsService userDetailsService() {

        }
    
        // 方式一: springboot 对 security 默认配置中,进行自动配置时,自动在工厂中创建全局 AuthenticationManager

> 配置全局 AuthenticationManager

*  默认全局 AuthenticationManager

@Configuration
    public class ApplicationSecurity extends WebSecurityConfigurerAdapter {
        
    
       ... // web stuff here
    
      @Autowired
      public void initialize(AuthenticationManagerBuilder builder) {
        
           // builder...
      }
    }

**总结**

1.  默认自动配置创建全局 AuthenticationManager 时，默认找当前项目中是否存在自定义的 UserDetailsService 实例，自动将当前项目 UserDetailsService 实例设置为数据源
2.  默认自动配置创建全局 AuthenticationManager 时，在工厂中使用时直接在代码中注入即可

*  自定义全局 AuthenticationManager

@Configuration
    public class ApplicationSecurity extends WebSecurityConfigurerAdapter {
        
    
       ... // web stuff here
    
      @Override
      public void configure(AuthenticationManagerBuilder builder) {
        
           // builder...
      }
    }

**总结**

1.  一旦通过 configure 方法自定义 AuthenticationManager 实现，就会将工厂中自动配置 AuthenticationManager 进行覆盖
2.  一旦通过 configure 方法自定义 AuthenticationManager 实现，需要在实现中指定认证数据源对象 **UserDetailsService**
3.  一旦通过 configure 方法自定义 AuthenticationManager 实现，这种方式创建的 AuthenticationManager 对象，是一个工厂内部本地的 AuthenticationManager 对象，不允许在其它自定义的组件中注入（@Autowired）

*  **用来在工厂中暴露自定义 AuthenticationManager 实例**

// 方式二: 自定义 AuthenticationManager(推荐)
    // 自定义的 AuthenticationManager 将会覆盖默认的配置,优先级更高(不支持自定义组件注入@Autowired)
    @Override
    public void configure(AuthenticationManagerBuilder builder) throws Exception {
        
        System.out.println("自定义AuthenticationManager: " + builder);
        builder.userDetailsService(userDetailsService());
    }
    
    // 作用: 用来将自定义的 AuthenticationManager 在工厂中进行暴露,可以在任何位置注入
    @Override
    @Bean
    public AuthenticationManager authenticationManager() throws Exception {
        
        return super.authenticationManager();
    }

      `credentialsNonExpired` TINYINT(1) DEFAULT NULL COMMENT '凭证过期',
      PRIMARY KEY (`id`)
    ) ENGINE=INNODB DEFAULT CHARSET=utf8
    
    - 角色表
    CREATE TABLE `role` (

#### 5.5 自定义数据源之实现 ####

1.  在`pom.xml`导入依赖

<dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.2.2</version>
    </dependency>
    
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.22</version>
    </dependency>
    
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>1.2.8</version>
    </dependency>

1.  配置`application.yml`文件

# 端口号
    server:
      port: 3035
    # 服务应用名称
    spring:
      application:
        name: SpringSecurity02
      # 关闭thymeleaf缓存(用于修改完之后立即生效)
      thymeleaf:
        cache: false
      # 数据源
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://localhost:3306/spring?useSSL=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
        username: root
        password: 123456
    mybatis:
      # 注意 mapper 映射文件必须使用"/"
      type-aliases-package: com.vinjcent.pojo
      mapper-locations: com/vinjcent/mapper/**/*.xml
    
    # 日志处理,为了展示 mybatis 运行 sql 语句
    logging:
      level:
        com:
          vinjcent:
            debug

1.  编写实体类User、Role

*  **User**

package com.vinjcent.pojo;
    
    import org.springframework.security.core.GrantedAuthority;
    import org.springframework.security.core.authority.SimpleGrantedAuthority;
    import org.springframework.security.core.userdetails.UserDetails;
    
    import java.util.*;
    
    // 自定义用户User
    public class User implements UserDetails {
        
    
        private Integer id; // 用户id
        private String username;    // 用户名
        private String password;    // 密码
        private boolean enabled;    // 是否可用
        private boolean accountNonExpired;  // 账户过期
        private boolean accountNonLocked;   // 账户锁定
        private boolean credentialsNonExpired;  // 凭证过期
        private List<Role> roles = new ArrayList<>();   // 用户角色信息
    
    
        // 返回权限信息
        @Override
        public Collection<? extends GrantedAuthority> getAuthorities() {
        
            Set<SimpleGrantedAuthority> authorities = new HashSet<>();
            roles.forEach(role -> {
        
                SimpleGrantedAuthority simpleGrantedAuthority = new SimpleGrantedAuthority(role.getName());
                authorities.add(simpleGrantedAuthority);
            });
            return authorities;
        }
    
        @Override
        public String getPassword() {
        
            return password;
        }
    
        @Override
        public String getUsername() {
        
            return username;
        }
    
        @Override
        public boolean isAccountNonExpired() {
        
            return accountNonExpired;
        }
    
        @Override
        public boolean isAccountNonLocked() {
        
            return accountNonLocked;
        }
    
        @Override
        public boolean isCredentialsNonExpired() {
        
            return credentialsNonExpired;
        }
    
        @Override
        public boolean isEnabled() {
        
            return enabled;
        }
    
        public void setId(Integer id) {
        
            this.id = id;
        }
    
        public void setUsername(String username) {
        
            this.username = username;
        }
    
        public void setPassword(String password) {
        
            this.password = password;
        }
    
        public void setEnabled(boolean enabled) {
        
            this.enabled = enabled;
        }
    
        public void setAccountNonExpired(boolean accountNonExpired) {
        
            this.accountNonExpired = accountNonExpired;
        }
    
        public void setAccountNonLocked(boolean accountNonLocked) {
        
            this.accountNonLocked = accountNonLocked;
        }
    
        public void setCredentialsNonExpired(boolean credentialsNonExpired) {
        
            this.credentialsNonExpired = credentialsNonExpired;
        }
    
        public void setRoles(List<Role> roles) {
        
            this.roles = roles;
        }
    
        public Integer getId() {
        
            return id;
        }
    
        public List<Role> getRoles() {
        
            return roles;
        }
    }

*  **Role**

package com.vinjcent.pojo;
    
    public class Role {
        
    
        private Integer id;
        private String name;
        private String nameZh;
    
        public Role() {
        
        }
    
        public Role(Integer id, String name, String nameZh) {
        
            this.id = id;
            this.name = name;
            this.nameZh = nameZh;
        }
    
        public Integer getId() {
        
            return id;
        }
    
        public void setId(Integer id) {
        
            this.id = id;
        }
    
        public String getName() {
        
            return name;
        }
    
        public void setName(String name) {
        
            this.name = name;
        }
    
        public String getNameZh() {
        
            return nameZh;
        }
    
        public void setNameZh(String nameZh) {
        
            this.nameZh = nameZh;
        }
    
        @Override
        public String toString() {
        
            return "Role{" +
                    "id=" + id +
                    ", name='" + name + '\'' +
                    ", nameZh='" + nameZh + '\'' +
                    '}';
        }
    }

1.  对应mapper映射文件

*  **UserMapper**

package com.vinjcent.mapper;
    
    import com.vinjcent.pojo.User;
    import org.apache.ibatis.annotations.Mapper;
    import org.apache.ibatis.annotations.Param;
    import org.springframework.stereotype.Repository;
    
    /**
     * @author vinjcent
     * @description 针对表【user】的数据库操作Mapper
     * @createDate 2022-09-25 12:03:42
     */
    @Mapper
    @Repository
    public interface UserMapper {
        
    
        // 根据用户名返回用户信息
        User queryUserByUsername(@Param("username") String username);
    
    
    }

*  **RoleMapper**

package com.vinjcent.mapper;
    
    
    import com.vinjcent.pojo.Role;
    import org.apache.ibatis.annotations.Mapper;
    import org.apache.ibatis.annotations.Param;
    import org.springframework.stereotype.Repository;
    
    import java.util.List;
    
    /**
     * @author vinjcent
     * @description 针对表【role】的数据库操作Mapper
     * @createDate 2022-09-25 12:01:18
     */
    @Mapper
    @Repository
    public interface RoleMapper {
        
    
        List<Role> queryRolesByUid(@Param("uid") Integer uid);
    
    }

【**注**】还需要些service层，这里就不给大家演示了

1.  编写实现接口 **UserDetailsService** 类 **DivUserDetailsService**

package com.vinjcent.config.security;
    
    import com.vinjcent.pojo.Role;
    import com.vinjcent.pojo.User;
    import com.vinjcent.service.RoleService;
    import com.vinjcent.service.UserService;
    import org.springframework.beans.factory.annotation.Autowired;
    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.Component;
    import org.springframework.util.ObjectUtils;
    
    import java.util.List;
    
    @Component
    public class DivUserDetailsService implements UserDetailsService {
        
    
        // dao ===> springboot + mybatis
        private final UserService userService;
    
        private final RoleService roleService;
    
        @Autowired
        public DivUserDetailsService(UserService userService, RoleService roleService) {
        
            this.userService = userService;
            this.roleService = roleService;
        }
    
        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        
            // 1.查询用户
            User user = userService.queryUserByUsername(username);
            if (ObjectUtils.isEmpty(user)) throw new UsernameNotFoundException("用户名不正确!");
            // 2.根据用户id查询角色信息
            List<Role> roles = roleService.queryRolesByUid(user.getId());
            user.setRoles(roles);
            return user;
        }
    }

1.  修改对应 **WebSecurityConfiguration** 配置类

package com.vinjcent.config.security;
