分布式認證概念說明
分布式認證,即我們常說的單點登錄,簡稱SSO,指的是在多應(yīng)用系統(tǒng)的項目中,用戶只需要登錄一次,就可以訪 問所有互相信任的應(yīng)用系統(tǒng)。
分布式認證流程圖
首先,我們要明確,在分布式項目中,每臺服務(wù)器都有各自獨立的session,而這些session之間是無法直接共享資 源的,所以,session通常不能被作為單點登錄的技術(shù)方案。最合理的單點登錄方案流程如下圖所示:
總結(jié)一下,單點登錄的實現(xiàn)分兩大環(huán)節(jié):
- **用戶認證:**這一環(huán)節(jié)主要是用戶向認證服務(wù)器發(fā)起認證請求,認證服務(wù)器給用戶返回一個成功的令牌token, 主要在認證服務(wù)器中完成,即圖中的A系統(tǒng),注意A系統(tǒng)只能有一個。
- **身份校驗:**這一環(huán)節(jié)是用戶攜帶token去訪問其他服務(wù)器時,在其他服務(wù)器中要對token的真?zhèn)芜M行檢驗,主 要在資源服務(wù)器中完成,即圖中的B系統(tǒng),這里B系統(tǒng)可以有很多個。
JWT介紹
概念說明
從分布式認證流程中,我們不難發(fā)現(xiàn),這中間起最關(guān)鍵作用的就是token,token的安全與否,直接關(guān)系到系統(tǒng)的 健壯性,這里我們選擇使用JWT來實現(xiàn)token的生成和校驗。 JWT,全稱JSON Web Token,官網(wǎng)地址https://jwt.io,是一款出色的分布式身份校驗方案??梢陨蓆oken,也可以解析檢驗token。
JWT生成的token由三部分組成
- 頭部:主要設(shè)置一些規(guī)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。【通過隨機鹽在進行加密】
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(dān)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(shù) 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(fā)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(yōu)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(shù)學(xué)家Rivest、Shamir 和 Adleman 設(shè)計了一種算法,可以實現(xiàn)非對稱加密。這種算法用他們?nèi)?個人的名字縮寫:RSA。
【總結(jié)】:也就是說,我們加密信息的時候,使用的是公鑰,而驗證token真?zhèn)蔚臅r候,使用的是公鑰

SpringSecurity+JWT+RSA分布式認證思路分析
SpringSecurity主要是通過過濾器來實現(xiàn)功能的!我們要找到SpringSecurity實現(xiàn)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(xiàn)認證功能,該過濾 器父類中successfulAuthentication方法實現(xiàn)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(xù)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(shù)是前后端分離的架構(gòu)設(shè)計,我們要滿足可以接受異步post的認證請求參數(shù),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(xiàn)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(xù)的授權(quán)功能可以正常使用。

編寫讀取公鑰的配置類
@ConfigurationProperties("rsa.key") public class RsaKeyProperties { private String pubKeyFile; private PublicKey publicKey; @PostConstruct public void createRsaKey() throws Exception { publicKey = RsaUtils.getPublicKey(pubKeyFile); } public String getPubKeyFile() { return pubKeyFile; } public void setPubKeyFile(String pubKeyFile) { this.pubKeyFile = pubKeyFile; } public PublicKey getPublicKey() { return publicKey; } public void setPublicKey(PublicKey publicKey) { this.publicKey = publicKey; } }
編寫啟動類
@SpringBootApplication @MapperScan("com.itheima.mapper") @EnableConfigurationProperties(RsaKeyProperties.class) public class AuthSourceApplication { public static void main(String[] args) { SpringApplication.run(AuthSourceApplication.class, args); } }
復(fù)制認證服務(wù)中,用戶對象,角色對象和校驗認證的接口
這時目錄結(jié)構(gòu)如圖:
復(fù)制認證服務(wù)中SpringSecurity配置類做修改,去掉“增加自定義認證過濾器”即可!
@Configuration @EnableWebSecurity @EnableGlobalMethodSecurity(securedEnabled=true) public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private RsaKeyProperties prop; //SpringSecurity配置信息 public void configure(HttpSecurity http) throws Exception { http.csrf() .disable() .authorizeRequests() .antMatchers("/product").hasAnyRole("USER") .anyRequest() .authenticated() .and() .addFilter(new JwtVerifyFilter(super.authenticationManager(), prop)) .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS); } }
編寫產(chǎn)品處理器
@RestController @RequestMapping("/product") public class ProductController { @GetMapping public String findAll(){ return "產(chǎn)品測試成功!"; } }
啟動產(chǎn)品服務(wù)做測試
攜帶token
在產(chǎn)品處理器上添加訪問需要ADMIN角色
@RestController @RequestMapping("/product") public class ProductController { @Secured("ROLE_ADMIN") @GetMapping public String findAll(){ return "產(chǎn)品測試成功!"; } }
重啟測試權(quán)限不足
在數(shù)據(jù)庫中手動給用戶添加ADMIN角色
重新認證獲取新token再測試OK了!
