Question

我在weblogic 12c上部署的Web应用程序中有一个ntlm过滤器，用于检索已记录的用户客户端名称，以便自动对其进行身份验证。

我的过滤器类如下。

问题在于weblogic response.flushBuffer()什么也没做。浏览器的状态页面为401。

此代码适用于Jetty Http Server。

有关如何解决这个问题的想法吗？

谢谢！

  }  
  }  
  } catch (Exception e) {  
  System.out.println(e);

  @Override  
  public void destroy() {  
  filterConfig = null;

这是Weblogic的一个问题。

我重新安装它，现在效果很好。
