詳解基於Spring Cloud幾行配置完成單點登錄開發

單點登錄概念

單點登錄（Single Sign On），簡稱為SSO，是目前比較流行的企業業務整合的解決方案之一。 SSO的定義是在多個應用系統中，用戶只需要登錄一次就可以訪問所有相互信任的應用系統。登錄邏輯如上圖

基於Spring 全家桶的實現

技術選型：

1. Spring Boot
2. Spring Cloud
3. Spring Security oAuth2

客戶端：

maven依賴

EnableOAuth2Sso 註解

入口類配置@@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認證服務器

認證服務器配置

@Configuration@Order(Integer.MIN_VALUE)@EnableAuthorizationServerpublic class PigAuthorizationConfig extends AuthorizationServerConfigurerAdapter { @Override public void configure(ClientDetailsS​​erviceConfigurer 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) .userDetailsS​​ervice(userDetailsS​​ervice); } @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; }}
