*  在实现SSO之前，先要说一下\*\*@EnableResourceServer**与**@EnableOAuth2Sso\*\*

1.  一般网关处我们使用EnableResourceServer时，可以支持任意的oauth2授权模型，网关声明称资源服务器可以配置ResourceServerConfigurerAdapter，我们可以配置放行的路径等等内容。
2.  如果网关处使用EnableOAuth2Sso，在所有请求转发之前就首先要到认证服务器上去校验信息，使用授权码模式，clientid与clientsecret来确认进行oauth2的登陆，跳转登陆页面在进行登陆。

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

#### 下面我们来简单搭建一个SSO的小项目 ####

*  搭建认证服务器
    
    我们将客户端信息存储在mysql中，token使用jwt。
    
    依赖包只需要oauth2，我cloud用的版本是Greenwich.SR2
    
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-oauth2</artifactId>
        </dependency>
    
    1.  配置AuthorizationServerConfigurerAdapter
        
            package cn.hs.sys.config;
            
            import org.springframework.beans.factory.annotation.Autowired;
            import org.springframework.context.annotation.Bean;
            import org.springframework.context.annotation.Configuration;
            import org.springframework.security.authentication.AuthenticationManager;
            import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
            import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
            import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
            import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
            import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
            import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
            import org.springframework.security.oauth2.provider.token.TokenStore;
            import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
            import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
            
            import javax.sql.DataSource;
            
            /** * @description: * @Author: huangsan * @Date: 2020/5/8 4:46 下午 */
            @Configuration
            @EnableAuthorizationServer
            public class OAuth2AuthServerConfig extends AuthorizationServerConfigurerAdapter { 
            
                @Autowired
                private AuthenticationManager authenticationManager;
                @Autowired
                private DataSource dataSource;
                @Autowired
                private BCryptPasswordEncoder passwordEncoder;
            
                @Override
                public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception { 
                    endpoints
                            .tokenStore(tokenStore())
                            .tokenEnhancer(jwtAccessTokenConverter())
                            .authenticationManager(authenticationManager);
                }
            
                @Bean
                public TokenStore tokenStore() { 
                    return new JwtTokenStore(jwtAccessTokenConverter());
                }
            
                @Bean
                public JwtAccessTokenConverter jwtAccessTokenConverter() { 
                    JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
                    converter.setSigningKey("123456");
                    return converter;
                }
            
                @Override
                public void configure(ClientDetailsServiceConfigurer clients) throws Exception { 
                    System.out.println("------"+passwordEncoder.encode("123456"));
                    clients.jdbc(dataSource);
                }
            
                @Override
                public void configure(AuthorizationServerSecurityConfigurer security) throws Exception { 
                    security
                            .tokenKeyAccess("isAuthenticated()")
                            .checkTokenAccess("isAuthenticated()");
                }
            }
    2.  配置WebSecurityConfigurerAdapter
        
            package cn.hs.sys.config;
            
            import org.springframework.beans.factory.annotation.Autowired;
            import org.springframework.context.annotation.Bean;
            import org.springframework.context.annotation.Configuration;
            import org.springframework.security.authentication.AuthenticationManager;
            import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
            import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
            import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
            import org.springframework.security.core.userdetails.UserDetailsService;
            import org.springframework.security.crypto.password.PasswordEncoder;
            
            /** * @description: * @Author: huangsan * @Date: 2020/5/8 4:47 下午 */
            @Configuration
            @EnableWebSecurity
            public class OAuth2WebSecurityConfig extends WebSecurityConfigurerAdapter { 
            
                @Autowired
                private UserDetailsService userDetailsService;
            
                @Autowired
                private PasswordEncoder passwordEncoder;
            
                @Override
                protected void configure(AuthenticationManagerBuilder auth) throws Exception { 
                    auth.userDetailsService(userDetailsService)
                            .passwordEncoder(passwordEncoder);
                }
              
                @Bean
                @Override
                public AuthenticationManager authenticationManagerBean() throws Exception { 
                    return super.authenticationManagerBean();
                }
            }
    3.  配置UserDetailsService（这里自己实现逻辑返回UserDetails即可）
        
            package cn.hs.sys.config;
            
            import cn.hs.sys.Constant;
            import cn.hs.sys.dao.SysUserEntity;
            import cn.hs.sys.dao.UserPermissionRepository;
            import org.apache.commons.lang.StringUtils;
            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;
            
            import javax.annotation.Resource;
            import java.util.ArrayList;
            import java.util.List;
            
            /** * @description: * @Author: huangsan * @Date: 2020/5/8 4:53 下午 */
            @Service
            public class UserDetailsServiceImpl implements UserDetailsService { 
            
                @Resource
                private UserPermissionRepository userPermissionRepository;
            
                @Override
                public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { 
                    if (StringUtils.isBlank(username)) { 
                        throw new UsernameNotFoundException("账号错误");
                    }
                    SysUserEntity sysUserEntity = userPermissionRepository.findUserIdByName(username);
                    if (sysUserEntity == null) { 
                        throw new UsernameNotFoundException("账号异常");
                    }
                    if (Constant.USER_OFF.equals(sysUserEntity.getUserStatus())) { 
                        throw new UsernameNotFoundException("账号状态异常");
                    }
                    if (sysUserEntity.getUserId() != null) { 
                        List<String> permissionStrs = userPermissionRepository.listPermissionById(sysUserEntity.getUserId());
            
                        List<GrantedAuthority> grantedAuthorities = new ArrayList<>();
                        permissionStrs.forEach(permissionStr -> { 
                            if (StringUtils.isNotBlank(permissionStr)) { 
                                GrantedAuthority grantedAuthority = new SimpleGrantedAuthority(permissionStr);
                                grantedAuthorities.add(grantedAuthority);
                            }
                        });
                        //密码加密方式为：passwordEncoder.encode()
                        return new User(username, sysUserEntity.getUserPassword(), grantedAuthorities);
                    } else { 
                        throw new UsernameNotFoundException("账号异常");
                    }
                }
            }
    4.  配置文件如下（没什么东西，主要就是mysql的内容，eureka自行去掉吧）
        
            server:
              port: 52188
            spring:
              application:
                name: hs-auth
              datasource:
                url: jdbc:mysql://localhost:3306/hs_cloud?characterEncoding=utf8&characterSetResults=utf8&autoReconnect=true&useSSL=false&allowPublicKeyRetrieval=true
                username: root
                password: 123456
                driver-class-name: com.mysql.cj.jdbc.Driver
            eureka:
              client:
                service-url:
                  defaultZone: http://127.0.0.1:52199/eureka

**认证服务器的内容基本都是一样，没什么特别的地方我就直接贴代码了，对于客户端来说有一些需要注意的地方。**

*  配置客户端
    
    **注意客户端不能使用EnableResourceServer注解**
    
    1.  引入相关依赖
        
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-oauth2</artifactId>
            </dependency>
    2.  在启动类上增加@EnableOAuth2Sso注解
    3.  创建测试web测试类，返回数据
    4.  配置yml文件
        
            server:
              port: 52109
              servlet:
                context-path: /sys #特别需要配置，如果是/会反复跳转登陆页面
            security:
              oauth2:
                resource:
                  jwt:
                    key-uri: http://localhost:52188/oauth/token_key
                client:
                  client-id: hs-system #客户端id
                  client-secret: 123456 #客户端口令
                  access-token-uri: http://localhost:52188/oauth/token #获取令牌路径
                  user-authorization-uri: http://localhost:52188/oauth/authorize #获取授权路径
 *  相同的方式配置另一个客户端
    
    和第一个客户端一样，**注意更改path**
 *  配置完客户端需要配置登陆跳转路径和自动授权（下面是sql插入语句自行修改）
    
    ``INSERT INTO `hs_cloud`.`oauth_client_details`(`client_id`, `resource_ids`, `client_secret`, `scope`, `authorized_grant_types`, `web_server_redirect_uri`, `authorities`, `access_token_validity`, `refresh_token_validity`, `additional_information`, `autoapprove`) VALUES ('hs-gateway', NULL, '$2a$10$p/siIwq2lUsOpg6gZC1V5epmeLMdO6BrfKnO36.5ZCn9eHOcibiUi', 'read', 'authorization_code,refresh_token,password', 'http://localhost:52100/zuul/login', NULL, 3600, 360000, NULL, 'read'); INSERT INTO `hs_cloud`.`oauth_client_details`(`client_id`, `resource_ids`, `client_secret`, `scope`, `authorized_grant_types`, `web_server_redirect_uri`, `authorities`, `access_token_validity`, `refresh_token_validity`, `additional_information`, `autoapprove`) VALUES ('hs-modules-back', NULL, '$2a$10$p/siIwq2lUsOpg6gZC1V5epmeLMdO6BrfKnO36.5ZCn9eHOcibiUi', 'read', 'authorization_code,refresh_token,password', 'http://localhost:52110/back/login', NULL, 3600, 360000, NULL, 'read');``
    
    **主要注意web\_server\_redirect\_uri与autoapprove，配置autoapprove可以跳过授权的步骤，直接授权**
 *  成果演示（文字描述是：俩个客户端访问的时候都会去授权服务器，如果没有登陆会跳转登陆页，当一个客户端登录后，可直接访问，不需登陆。视频传上来好麻烦，就不传了，手动狗头。）
