我正在尝试实现一个简单的客户端凭据流spring-security-oauth2 api。我尝试改编sparklr和tonr示例，但没有成功。我还尝试遵循此线程的代码：2腿（客户端凭据）OAuth2服务器的Spring-security上下文设置，但它似乎不适用于我。有人可以给我看一个例子，或者可以帮助我完成该工作。

尝试对Sparklr应用程序上的tonr应用程序进行身份验证时出现以下错误：
HTTP状态500-请求处理失败；嵌套的异常为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
您可以尝试允许匿名访问/oauth/token端点。这是我可以使我的client_credentials流正常工作的唯一方法。
更改此行
<intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY" />
对此
<intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_ANONYMOUSLY" />
并删除此行：
<anonymous enabled="false" />
希望能有所帮助。
