Spring Security基于JWT实现SSO单点登录详解

时间：2021-05-20

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-demo

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://maSeparatedStringToAuthorityList("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=9999server.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@EnableOAuth2Ssopublic 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=client1security.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#ssoserver.port=8080server.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@EnableOAuth2Ssopublic 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=client2security.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#ssoserver.port=8060server.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
