我们使用 Spring Security OAuth2 保护我们的 REST 服务（用于服务器到服务器的通信，不涉及用户）。但是，当尝试在浏览器中访问受保护的资源时，它会显示：

<oauth>
    <error_description>
        An Authentication object was not found in the SecurityContext
    </error_description>
    <error>unauthorized</error>
</oauth>

我们希望这是我们自己选择的自定义页面。有办法吗？

设置 access-denied-page 是不行的。一方面，它需要定义一个我们没有的登录页面，因为这是一个纯服务器到服务器的通信。另一方面，这个属性据说自 Spring 3.0.. 或其他东西以来已被弃用。

无论如何.. 调试我进入 OAuth 错误处理的方式。并发现响应似乎以某种方式丰富了我在错误页面上看到的信息。显然根本没有完成页面渲染，所以看起来没有要替换的错误页面..？！

至少我们想隐藏我们使用 OAuth 的事实，如果我们不能有一个“真实”页面，则只显示一个基本的“拒绝”文本。所以也许我必须扩展 spring 安全处理程序或添加一个自定义过滤器修改响应？！

也许重定向到我们的错误页面？

谢谢！

I had to remove the oauth detail too and my solution was to implement my own OAuth2ExceptionRenderer

package org.some.nice.code;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpInputMessage;
import org.springframework.http.HttpOutputMessage;
import org.springframework.http.ResponseEntity;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.http.server.ServletServerHttpRequest;
import org.springframework.http.server.ServletServerHttpResponse;
import org.springframework.security.oauth2.provider.error.OAuth2ExceptionRenderer;
import org.springframework.web.context.request.NativeWebRequest;
import org.springframework.web.context.request.ServletWebRequest;

public class HeaderOnlyOAuth2ExceptionRenderer implements OAuth2ExceptionRenderer
{
    private final Log logger = LogFactory
            .getLog(MyOAuth2ExceptionRenderer.class);

    public void handleHttpEntityResponse(HttpEntity<?> responseEntity,
            ServletWebRequest webRequest) throws Exception
    {
        if (responseEntity == null)
        {
            return;
        }
        HttpInputMessage inputMessage = createHttpInputMessage(webRequest);
        HttpOutputMessage outputMessage = createHttpOutputMessage(webRequest);
        logger.info("filtering headers only...");
        if (responseEntity instanceof ResponseEntity
                && outputMessage instanceof ServerHttpResponse)
        {
            ((ServerHttpResponse) outputMessage)
                    .setStatusCode(((ResponseEntity<?>) responseEntity)
                            .getStatusCode());
        }
        HttpHeaders entityHeaders = responseEntity.getHeaders();
        if (!entityHeaders.isEmpty())
        {
            outputMessage.getHeaders().putAll(entityHeaders);
        }
    }

    private HttpInputMessage createHttpInputMessage(NativeWebRequest webRequest)
            throws Exception
    {
        HttpServletRequest servletRequest = webRequest
                .getNativeRequest(HttpServletRequest.class);
        return new ServletServerHttpRequest(servletRequest);
    }

    private HttpOutputMessage createHttpOutputMessage(
            NativeWebRequest webRequest) throws Exception
    {
        HttpServletResponse servletResponse = (HttpServletResponse) webRequest
                .getNativeResponse();
        return new ServletServerHttpResponse(servletResponse);
    }
}

Then you will have to reference it within your spring context

     <bean id="oauthAuthenticationEntryPoint" class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint">
        <property name="realmName" value="theRealm" />
<property name="exceptionRenderer" ref="headerOnlyExceptionRender" />
    </bean>

    <bean id="clientAuthenticationEntryPoint" class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint">
        <property name="realmName" value="theRealm/client" />
        <property name="typeName" value="Basic" />
<property name="exceptionRenderer" ref="headerOnlyExceptionRender" />
    </bean>



    <bean id="oauthAccessDeniedHandler" class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler">
<property name="exceptionRenderer" ref="headerOnlyExceptionRender" />
</bean>


    <bean id="headerOnlyExceptionRender" class="org.some.nice.code.HeaderOnlyOAuth2ExceptionRenderer"/>

Hope it helps.
