單點登錄SSO方法之SpringSecurity+JWT實現一、什么是單點登陸二、簡單的運行機制三、JWT介紹概念說明JWT生成的token由三部分組成：JWT生成token的安全性分析非對稱加密RS

發布時間：2023-07-03 11:15:33 作者：網友整理

通過前面幾篇文章我們詳細的介紹了SpringSecurity的使用，本文我們來看下，結合JWT來實現單點登錄操作。

一、什么是單點登陸

  單點登錄（Single Sign On），簡稱為 SSO，是目前比較流行的企業業務整合的解決方案之一。SSO的定義是在多個應用系統中，用戶只需要登錄一次就可以訪問所有相互信任的應用系統

二、簡單的運行機制

  單點登錄的機制其實是比較簡單的，用一個現實中的例子做比較。某公園內部有許多獨立的景點，游客可以在各個景點門口單獨買票。對于需要游玩所有的景點的游客，這種買票方式很不方便，需要在每個景點門口排隊買票，錢包拿 進拿出的，容易丟失，很不安全。于是絕大多數游客選擇在大門口買一張通票（也叫套票），就可以玩遍所有的景點而不需要重新再買票。他們只需要在每個景點門 口出示一下剛才買的套票就能夠被允許進入每個獨立的景點。
單點登錄的機制也一樣，如下圖所示，

單點登錄SSO方法之SpringSecurity+JWT實現

 

用戶認證：這一環節主要是用戶向認證服務器發起認證請求，認證服務器給用戶返回一個成功的令牌token，主要在認證服務器中完成，即圖中的認證系統，注意認證系統只能有一個。
身份校驗：這一環節是用戶攜帶token去訪問其他服務器時，在其他服務器中要對token的真偽進行檢驗，主要在資源服務器中完成，即圖中的應用系統2 3

三、JWT介紹

概念說明

  從分布式認證流程中，我們不難發現，這中間起最關鍵作用的就是token，token的安全與否，直接關系到系統的健壯性，這里我們選擇使用JWT來實現token的生成和校驗。
  JWT，全稱JSON Web Token，官網地址https://jwt.io，是一款出色的分布式身份校驗方案。可以生成token，也可以解析檢驗token。

JWT生成的token由三部分組成：

頭部：主要設置一些規范信息，簽名部分的編碼格式就在頭部中聲明。
載荷：token中存放有效信息的部分，比如用戶名，用戶角色，過期時間等，但是不要放密碼，會泄露！
簽名：將頭部與載荷分別采用base64編碼后，用“.”相連，再加入鹽，最后使用頭部聲明的編碼類型進行編碼，就得到了簽名。

JWT生成token的安全性分析

  從JWT生成的token組成上來看，要想避免token被偽造，主要就得看簽名部分了，而簽名部分又有三部分組成，其中頭部和載荷的base64編碼，幾乎是透明的，毫無安全性可言，那么最終守護token安全的重擔就落在了加入的鹽上面了！試想：如果生成token所用的鹽與解析token時加入的鹽是一樣的。豈不是類似于中國人民銀行把人民幣防偽技術公開了？大家可以用這個鹽來解析token，就能用來偽造token。這時，我們就需要對鹽采用非對稱加密的方式進行加密，以達到生成token與校驗token方所用的鹽不一致的安全效果！

非對稱加密RSA介紹

基本原理：同時生成兩把密鑰：私鑰和公鑰，私鑰隱秘保存，公鑰可以下發給信任客戶端
私鑰加密，持有私鑰或公鑰才可以解密
公鑰加密，持有私鑰才可解密
優點：安全，難以破解
缺點：算法比較耗時，為了安全，可以接受
歷史：三位數學家Rivest、Shamir 和 Adleman 設計了一種算法，可以實現非對稱加密。這種算法用他們三個人的名字縮寫：RSA。

四、SpringSecurity整合JWT

1.認證思路分析

  SpringSecurity主要是通過過濾器來實現功能的！我們要找到SpringSecurity實現認證和校驗身份的過濾器！

回顧集中式認證流程

用戶認證：
  使用UsernamePasswordAuthenticationFilter過濾器中attemptAuthentication方法實現認證功能，該過濾器父類中successfulAuthentication方法實現認證成功后的操作。
身份校驗：
  使用BasicAuthenticationFilter過濾器中doFilterInternal方法驗證是否登錄，以決定能否進入后續過濾器。

分析分布式認證流程

用戶認證：
  由于分布式項目，多數是前后端分離的架構設計，我們要滿足可以接受異步post的認證請求參數，需要修改UsernamePasswordAuthenticationFilter過濾器中attemptAuthentication方法，讓其能夠接收請求體。
  另外，默認successfulAuthentication方法在認證通過后，是把用戶信息直接放入session就完事了，現在我們需要修改這個方法，在認證通過后生成token并返回給用戶。
身份校驗：
  原來BasicAuthenticationFilter過濾器中doFilterInternal方法校驗用戶是否登錄，就是看session中是否有用戶信息，我們要修改為，驗證用戶攜帶的token是否合法，并解析出用戶信息，交給SpringSecurity，以便于后續的授權功能可以正常使用。

2.具體實現

  為了演示單點登錄的效果，我們設計如下項目結構

單點登錄SSO方法之SpringSecurity+JWT實現

 

2.1父工程創建

  因為本案例需要創建多個系統，所以我們使用maven聚合工程來實現，首先創建一個父工程，導入springboot的父依賴即可

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.3.RELEASE</version>
    <relativePath/>
</parent>
123456

2.2公共工程創建

  然后創建一個common工程，其他工程依賴此系統

說明
資源服務可以有很多個，這里只拿產品服務為例，記住，資源服務中只能通過公鑰驗證認證。不能簽發token！創建產品服務并導入jar包根據實際業務導包即可，咱們就暫時和認證服務一樣了。

接下來我們再創建一個資源服務
