擴充套件jwt解決oauth2 效能瓶頸

資源伺服器的請求都會被攔截 到認證伺服器校驗合法性 （如下圖）

如上步驟在實際使用，會造成認證中心的負載壓力過大，成為造成整個系統瓶頸的關鍵點。

check-token 過程中涉及的原始碼

@bean

public tokenenhancer tokenenhancer() 
final mapadditionalinfo = new hashmap<>(8);
pigxuser pigxuser = (pigxuser) authentication.getuserauthentication().getprincipal();
additionalinfo.put("user_id", pigxuser.getid());
additionalinfo.put("username", pigxuser.getusername());
additionalinfo.put("dept_id", pigxuser.getdeptid());
additionalinfo.put("tenant_id", pigxuser.gettenantid());
additionalinfo.put("license", securityconstants.pigx_license);
((defaultoauth2accesstoken) accesstoken).setadditionalinformation(additionalinfo);
return accesstoken;};}

public class pigxcustomtokenservices implements resourceservertokenservices

public oauth2accesstoken readaccesstoken(string accesstoken)
