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

  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;
  }
}
