我正在尝试实现一个简单的客户端凭据流 spring-security-oauth2 api。我试图改编 sparklr 和 tonr 的例子，但没有成功。我还尝试遵循此线程的代码：Spring-security context setup for 2-legged (client credentials) OAuth2 server但它似乎不适用于我。有人可以给我看一个例子或帮助我完成这项工作。

尝试在 sparklr 应用程序上验证 tonr 应用程序时出现以下错误：
HTTP 状态 500 - 请求处理失败；嵌套异常是 error="access_denied", error_description="请求访问令牌时出错。
我希望有一个人可以帮助我。谢谢
