Spring Cloud Security 爲構建安全的SpringBoot應用提供了一系列解決方案,結合Oauth2還能夠實現更多功能,好比使用JWT令牌存儲信息,刷新令牌功能,本文將對其結合JWT使用進行詳細介紹。git
JWT是JSON WEB TOKEN的縮寫,它是基於 RFC 7519 標準定義的一種能夠安全傳輸的的JSON對象,因爲使用了數字簽名,因此是可信任和安全的。github

該模塊只是對oauth2-server模塊的擴展,直接複製過來擴展下下便可。web
在上一節中咱們都是把令牌存儲在內存中的,這樣若是部署多個服務,就會致使沒法使用令牌的問題。 Spring Cloud Security中有兩種存儲令牌的方式可用於解決該問題,一種是使用Redis來存儲,另外一種是使用JWT來存儲。redis

有時候咱們須要擴展JWT中存儲的內容,這裏咱們在JWT中擴展一個key爲
enhance
,value爲enhance info
的數據。算法

public class JwtTokenEnhancer implements TokenEnhancer {
@Override
public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {

((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(info);
return accessToken;

若是咱們須要獲取JWT中的信息,可使用一個叫jjwt的工具包。spring

Authorization
頭中,訪問以下地址獲取信息:http://localhost:9401/user/getCurrentUser在Spring Cloud Security 中使用oauth2時,若是令牌失效了,可使用刷新令牌經過refresh_token的受權模式再次獲取access_token。json
/** * 認證服務器配置 * Created by macro on 2019/9/30. */
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
