Spring Security基于JWT实现SSO单点登录详解

SSO ：同一个帐号在同一个公司不同系统上登陆

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

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-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

/**
 * 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

/**
 * 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<String, Object> 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<String, Object> 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<String, Object> model, HttpServletRequest request) {
    StringBuilder builder = new StringBuilder("<ul>");
    @SuppressWarnings("unchecked")
    Map<String, String> scopes = (Map<String, String>) (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("</ul>");
    return builder.toString();
  }

  private static String CSRF = "<input type='hidden' name='${_csrf.parameterName}' value='${_csrf.token}' />";

  private static String DENIAL = "<form id='denialForm' name='denialForm' action='${path}/oauth/authorize' method='post'><input name='user_oauth_approval' value='false' type='hidden'/>%csrf%<label><input name='deny' value='Deny' type='submit'/></label></form>";

  // 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 = "<html><body><div style='display:none;'> <h1>OAuth Approval</h1>"
      + "<p>Do you authorize '${authorizationRequest.clientId}' to access your protected resources?</p>"
      + "<form id='confirmationForm' name='confirmationForm' action='${path}/oauth/authorize' method='post'><input name='user_oauth_approval' value='true' type='hidden'/>%csrf%%scopes%<label><input name='authorize' value='Authorize' type='submit'/></label></form>"
      + "%denial%</div><script>document.getElementById('confirmationForm').submit();</script></body></html>";

  private static String SCOPE = "<li><div class='form-group'>%scope%: <input type='radio' name='%key%'"
      + " value='true'%approved%>Approve</input> <input type='radio' name='%key%' value='false'%denied%>Deny</input></div></li>";

}

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

/**
 * Created by ZhuPengWei on 2018/1/11.
 */
@SpringBootApplication
@RestController
@EnableOAuth2Sso
public class SsoClient1Application {

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

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

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>SSO Client1</title>
</head>
<body>
<h1>SSO Demo Client1</h1>
<a href="http://127.0.0.1:8060/client2/index.html" rel="external nofollow" >访问client2</a>

</body>
</html>

application.properties

security.oauth2.client.client-id=client1
security.oauth2.client.client-secret=client1
#需要认证时候跳转的地址
security.oauth2.client.user-authorization-uri=http://127.0.0.1:9999/server/oauth/authorize
#请求令牌地址
security.oauth2.client.access-token-uri=http://127.0.0.1:9999/server/oauth/token
#解析
security.oauth2.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
@EnableOAuth2Sso
public class SsoClient2Application {

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

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

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>SSO Client2</title>
</head>
<body>
<h1>SSO Demo Client2</h1>
<a href="http://127.0.0.1:8080/client1/index.html" rel="external nofollow" >访问client1</a>

</body>
</html>

security.oauth2.client.client-id=client2
security.oauth2.client.client-secret=client2
#需要认证时候跳转的地址
security.oauth2.client.user-authorization-uri=http://127.0.0.1:9999/server/oauth/authorize
#请求令牌地址
security.oauth2.client.access-token-uri=http://127.0.0.1:9999/server/oauth/token
#解析
security.oauth2.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

登陆成功之后

图2

图3

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

点击Authorize才会跳转到图2
