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。我也试过按照这个帖子的代码：Spring-security context setup for 2-legged (client credentials) OAuth2 server但它似乎不适合我。 有人可以给我一个例子，或者帮助我做我必须做的工作。
sparklr应用程序中的spring-servlet.xml

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 =“请求访问时出错 令牌。
我希望有人可以帮助我。谢谢
答案 0 :(得分：3)
您可以尝试允许匿名访问/oauth/token端点。这是我可以让client_credentials流程工作的唯一方法。
更改此行
<intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY" />
到这个
<intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_ANONYMOUSLY" />
并删除此行：
<anonymous enabled="false" />
希望有所帮助。
答案 1 :(得分：-4)
替换此行
<oauth:resource id="sparklr" type="client_credentials" client-id="tonr" client-secret="secret"
access-token-uri="${accessTokenUri}" scope="read,write" />
通过
<oauth:resource id="sparklr" type="authorization_code" client-id="tonr" client-secret="secret"
access-token-uri="${accessTokenUri}" scope="read,write" />
错误是el类型client_credentials并由authorization_code替换，并且可以正常工作。
