详解基于Spring Cloud几行配置完成单点登录开发

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：

1. Spring Boot
2. Spring Cloud
3. 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;  }}
