由于 SPNEGO 的原因，httpclient 不会使用您发布的代码段代码（凭据类内容设置）进行身份验证。
您可以使用DoAs + CallBackhandler在运行时传递用户和密码。
然后你需要一个login.conf或任何名称，里面有这个：
KrbLogin{
com.sun.security.auth.module.Krb5LoginModule required doNotPrompt=false debug=true useTicketCache=false;
};
您可以将名称从“KrbLogin”更改为您喜欢的名称（请记住在java代码中使用相同的名称）
并使用 java 系统属性进行设置：
System.setProperty("java.security.auth.login.config", "login.conf");
或
-Djava.security.auth.login.config=login.config
然后你需要一个 krb5 配置文件（通常是 krb5.ini 或 krb5.conf，里面有正确的配置）
如果你的工作站（或服务器）为Kerberos正确配置了，这个类应该按原样工作（使用propper文件login.conf和krb5.ini）我使用httpclient 4.3.3和java 1.7来测试它：

注意：
您可以使用：
System.setProperty("sun.security.krb5.debug", "true");
艺术
-Dsun.security.krb5.debug=true
以调查问题。
