单点登录概念

单点登录(Single Sign On),简称为 SSO,是目前比较流行的企业业务整合的解决方案之一。SSO的定义是在多个应用系统中,用户只需要登录一次就可以访问所有相互信任的应用系统。登录逻辑如上图

基于Spring 全家桶的实现

技术选型:

Spring Boot
Spring Cloud 
Spring Security oAuth2

客户端:

maven依赖


   org.springframework.boot
   spring-boot-starter-web


    org.springframework.boot
    spring-boot-starter-security


    org.springframework.security.oauth
    spring-security-oauth2


    org.springframework.security
    spring-security-jwt

EnableOAuth2Sso 注解

入口类配置@@EnableOAuth2Sso


@SpringBootApplication
public class PigSsoClientDemoApplication {

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

}

配置文件

security:
  oauth2:
    client:
      client-id: pig
      client-secret: pig
      user-authorization-uri: http://localhost:3000/oauth/authorize
      access-token-uri: http://localhost:3000/oauth/token
      scope: server
    resource:
      jwt:
        key-uri: http://localhost:3000/oauth/token_key
  sessions: never

SSO认证服务器

认证服务器配置

@Configuration
@Order(Integer.MIN_VALUE)
@EnableAuthorizationServer
public class PigAuthorizationConfig extends AuthorizationServerConfigurerAdapter {

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient(authServerConfig.getClientId())
                .secret(authServerConfig.getClientSecret())
                .authorizedGrantTypes(SecurityConstants.REFRESH_TOKEN, SecurityConstants.PASSWORD,SecurityConstants.AUTHORIZATION_CODE)
                .scopes(authServerConfig.getScope());
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints
                .tokenStore(new RedisTokenStore(redisConnectionFactory))
                .accessTokenConverter(jwtAccessTokenConverter())
                .authenticationManager(authenticationManager)
                .exceptionTranslator(pigWebResponseExceptionTranslator)
                .reuseRefreshTokens(false)
                .userDetailsService(userDetailsService);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                .allowFormAuthenticationForClients()
                .tokenKeyAccess("isAuthenticated()")
                .checkTokenAccess("permitAll()");
    }

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

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
        jwtAccessTokenConverter.setSigningKey(CommonConstant.SIGN_KEY);
        return jwtAccessTokenConverter;
    }

}

配置完成体验

  1. 访问SSO客户端的 index.html
  2. 重定向到SSO服务端的 Basic 认证
  3. 输入账号密码又重定向到原请求的 客户端index资源

总结

  • 客户端访问服务端 403问题? 用户需要拥有ROLE_USER的权限,具体的可以通过日志可以查看到报错。
  • Possible CSRF detected - state parameter was present but no state could be found 目前是通过设置session: never或者 cotext-path解决
  • 源码请参考 https://gitee.com/log4j/ 基于Spring Cloud、Spring Security Oauth2.0开发企业级认证与授权,提供常见服务监控、链路追踪、日志分析、缓存管理、任务调度等实现
