资源服务器就是业务服务 如用户服务,订单服务等 第三方需要到资源服务器调用接口获取资源
ResourceServerConfig
ResourceServerConfig是资源服务器的核心配置 用于验证token 与网关配置相似
其中.antMatchers("/**").access("#oauth2.hasScope('user')") 需要oauth_client_details表的scope配合 意思是访问所有资源 需要客户端有scope需要有user

application.yml
那么小伙伴又问了 既然网关验证token的有效性 那么资源服务器是不是就不用验证啦 答案是否 因为不添加配置 会报错 同样需要在application中添加以下配置
其他配置也spirng boot为准 这里不多说
