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

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId></dependency><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId></dependency><dependency> <groupId>org.springframework.security.oauth</groupId> <artifactId>spring-security-oauth2</artifactId></dependency><dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-jwt</artifactId></dependency>

EnableOAuth2Sso 注解

入口类配置@@EnableOAuth2Sso

@SpringBootApplicationpublic 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)@EnableAuthorizationServerpublic 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; }}
