Spring Security基于JWT实现SSO单点登录详解

使用SpringSecurity实现类似于SSO登陆系统是十分简单的下面我就搭建一个DEMO

首先来看看目录的结构

Spring Security基于JWT实现SSO单点登录详解

其中sso-demo是父工程项目 sso-client 、sso-client2分别对应2个资源服务器，sso-server是认证服务器

引入的pom文件

sso-demo

<?xml version="1.0" encoding="UTF-8"?>

  4.0.0

  study.security.sso
  sso-demo
  1.0.0-SNAPSHOT
  
    sso-server
    sso-client
    sso-client2
  
  pom

  
    
      
        io.spring.platform
        platform-bom
        Brussels-SR4
        pom
        import
      
      
        org.springframework.cloud
        spring-cloud-dependencies
        Dalston.SR2
        pom
        import
      
    
  

  
    
      
        org.apache.maven.plugins
        maven-compiler-plugin
        2.3.2
        
          1.8
          1.8
          UTF-8

sso-server

<?xml version="1.0" encoding="UTF-8"?>

  
    sso-demo
    study.security.sso
    1.0.0-SNAPSHOT
  
  4.0.0

  sso-server

  
    
      org.springframework.boot
      spring-boot-starter-security
    
    
      org.springframework.boot
      spring-boot-starter-web
    
    
      org.springframework.security.oauth
      spring-security-oauth3
    
    
      org.springframework.security
      spring-security-jwt

sso-client与sso-client2 pom 中的是一样的

1.sso-server

现在开始搭建认证服务器

认证服务器的目录结构如下

Spring Security基于JWT实现SSO单点登录详解

/**
 * 认证服务器配置
 * Created by ZhuPengWei on 2018/1/11.
 */
@Configuration
@EnableAuthorizationServer
public class SsoAuthenticationServerConfig extends AuthorizationServerConfigurerAdapter {

  @Override
  public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
        .withClient("client1")
        .secret("client1")
        .authorizedGrantTypes("authorization_code", "refresh_token")
        .scopes("all")
        .and()
        .withClient("client2")
        .secret("client2")
        .authorizedGrantTypes("authorization_code", "refresh_token")
        .scopes("all");
  }

  @Override
  public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints.tokenStore(jwtTokenStore()).accessTokenConverter(jwtAccessTokenConverter());
  }


  /**
   * 认证服务器的安全配置
   *
   * @param security
   * @throws Exception
   */
  @Override
  public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
    // 要访问认证服务器tokenKey的时候需要经过身份认证
    security.tokenKeyAccess("isAuthenticated()");
  }

  @Bean
  public TokenStore jwtTokenStore() {
    return new JwtTokenStore(jwtAccessTokenConverter());
  }

  @Bean
  public JwtAccessTokenConverter jwtAccessTokenConverter() {
    JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
    // 保证JWT安全的唯一方式
    jwtAccessTokenConverter.setSigningKey("ZPW");
    return jwtAccessTokenConverter;
  }
}

/**
 * 自定义用户登陆逻辑配置
 * Created by ZhuPengWei on 2018/1/13.
 */
@Configuration
public class SsoSecurityConfig extends WebSecurityConfigurerAdapter {

  @Autowired
  private UserDetailsService userDetailsService;

  /**
   * 加密解密逻辑
   */
  @Bean
  public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
  }

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    // 改成表单登陆的方式 所有请求都需要认证
    http.formLogin().and().authorizeRequests().anyRequest().authenticated();
  }

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    // 用自己的登陆逻辑以及加密器
    auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
  }
}

/**
 * 自定义用户登陆
 * Created by ZhuPengWei on 2018/1/13.
 */
@Component
public class SsoUserDetailsService implements UserDetailsService {

  @Autowired
  private PasswordEncoder passwordEncoder;

  @Override
  public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

    return new User(username,
        passwordEncoder.encode("123456"),
        AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER"));
  }
}

其中SsoApprovalEndPoint与SsoSpelView目的是去掉登陆之后授权的效果

注解 @FrameworkEndpoint

与@RestController注解相类似

如果声明和@FrameworkEndpoint一模一样的@RequestMapping

Spring框架处理的时候会优先处理@RestController里面的

Spring Security基于JWT实现SSO单点登录详解

/**
 * 自定义认证逻辑
 * Created by ZhuPengWei on 2018/1/13.
 */
@RestController
@SessionAttributes("authorizationRequest")
public class SsoApprovalEndpoint {

  @RequestMapping("/oauth/confirm_access")
  public ModelAndView getAccessConfirmation(Map model, HttpServletRequest request) throws Exception {
    String template = createTemplate(model, request);
    if (request.getAttribute("_csrf") != null) {
      model.put("_csrf", request.getAttribute("_csrf"));
    }
    return new ModelAndView(new SsoSpelView(template), model);
  }

  protected String createTemplate(Map model, HttpServletRequest request) {
    String template = TEMPLATE;
    if (model.containsKey("scopes") || request.getAttribute("scopes") != null) {
      template = template.replace("%scopes%", createScopes(model, request)).replace("%denial%", "");
    } else {
      template = template.replace("%scopes%", "").replace("%denial%", DENIAL);
    }
    if (model.containsKey("_csrf") || request.getAttribute("_csrf") != null) {
      template = template.replace("%csrf%", CSRF);
    } else {
      template = template.replace("%csrf%", "");
    }
    return template;
  }

  private CharSequence createScopes(Map model, HttpServletRequest request) {
    StringBuilder builder = new StringBuilder("");
    @SuppressWarnings("unchecked")
    Map scopes = (Map) (model.containsKey("scopes") ? model.get("scopes") : request
        .getAttribute("scopes"));
    for (String scope : scopes.keySet()) {
      String approved = "true".equals(scopes.get(scope)) ? " checked" : "";
      String denied = !"true".equals(scopes.get(scope)) ? " checked" : "";
      String value = SCOPE.replace("%scope%", scope).replace("%key%", scope).replace("%approved%", approved)
          .replace("%denied%", denied);
      builder.append(value);
    }
    builder.append("");
    return builder.toString();
  }

  private static String CSRF = "";

  private static String DENIAL = "%csrf%";

  // 对源代码进行处理 隐藏授权页面，并且使他自动提交
  private static String TEMPLATE = " OAuth Approval"
      + "Do you authorize '${authorizationRequest.clientId}' to access your protected resources?"
      + "%csrf%%scopes%"
      + "%denial%
";

  private static String SCOPE = "%scope%: Approve Deny";

}

SsoSpelView 与原来SpelView 是一样的只不过原来SpelView 不是public的类

application.properties

server.port=9999
server.context-path=/server

2.sso-client

相对于认证服务器资源服务器demo的配置就十分简单了

Spring Security基于JWT实现SSO单点登录详解

/**
 * Created by ZhuPengWei on 2018/1/11.
 */
@SpringBootApplication
@RestController
@EnableOAuth3Sso
public class SsoClient1Application {

  @GetMapping("/user")
  public Authentication user(Authentication user) {
    return user;
  }

  public static void main(String[] args) {
    SpringApplication.run(SsoClient1Application.class, args);
  }
}




  
  SSO Client1


SSO Demo Client1
访问client2

application.properties

security.oauth3.client.client-id=client1
security.oauth3.client.client-secret=client1
#需要认证时候跳转的地址
security.oauth3.client.user-authorization-uri=http://127.0.0.1:9999/server/oauth/authorize
#请求令牌地址
security.oauth3.client.access-token-uri=http://127.0.0.1:9999/server/oauth/token
#解析
security.oauth3.resource.jwt.key-uri=http://127.0.0.1:9999/server/oauth/token_key


#sso
server.port=8080
server.context-path=/client1

3.sso-client2

资源服务器1和资源服务器2的目录结构是一样的，改了相关的参数

/**
 * Created by ZhuPengWei on 2018/1/11.
 */
@SpringBootApplication
@RestController
@EnableOAuth3Sso
public class SsoClient2Application {

  @GetMapping("/user")
  public Authentication user(Authentication user) {
    return user;
  }

  public static void main(String[] args) {
    SpringApplication.run(SsoClient2Application.class, args);
  }
}




  
  SSO Client2


SSO Demo Client2
访问client1

security.oauth3.client.client-id=client2
security.oauth3.client.client-secret=client2
#需要认证时候跳转的地址
security.oauth3.client.user-authorization-uri=http://127.0.0.1:9999/server/oauth/authorize
#请求令牌地址
security.oauth3.client.access-token-uri=http://127.0.0.1:9999/server/oauth/token
#解析
security.oauth3.resource.jwt.key-uri=http://127.0.0.1:9999/server/oauth/token_key


#sso
server.port=8060
server.context-path=/client2

好了基于JWT实现SSO单点登录的DEMO以及搭建完成了下面来看看页面的效果

在初次访问的时候

图1

Spring Security基于JWT实现SSO单点登录详解

登陆成功之后

图2

Spring Security基于JWT实现SSO单点登录详解

图3

Spring Security基于JWT实现SSO单点登录详解

注意

写SsoApprovalEndPoint与SsoSpelView目的是去掉登陆之后授权的效果如果不写这2个类

在初次访问的登陆成功之后是有一步授权的操作的

比如说图1操作成功之后

Spring Security基于JWT实现SSO单点登录详解

点击Authorize才会跳转到图2
