使用spring-cloud-security-oauth2来实现oauth server和resource server,oauth Server和resource Server分开,resource Server实现了两种方式,一种是当用token调用受保护资源时,使用RemoteTokenServices来去oauth server去校验。另一种是共享数据库,然后资源服务器自己通过数据库进行校验。
使用spring-cloud-security-oauth2来实现oauth server和resource server,oauth Server和resource Server分开,oauth Server和resource Server使用了jwt的方式进行了实现。认证服务器生成jwt格式的token,并不对其进行持久化,然后资源服务器使用密钥进行校验token。
