Java访问http用户验证

public class SAXParse {
     static final String kuser = "admin";
     static final String kpass = "admin";

     static class MyAuthenticator extends Authenticator {
        @Override
        protected PasswordAuthentication getPasswordAuthentication() {
            return (new PasswordAuthentication(kuser,kpass.toCharArray()));
        }
    }
    public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
        Authenticator.setDefault(new MyAuthenticator());
        SAXParserFactory factory = SAXParserFactory.newInstance();
        SAXParser parser = factory.newSAXParser();
        parser.parse("http://172.16.1.15:8161/admin/xml/queues.jsp",new MQHandler());

    }
}

　　这里使用SAX解析器解析AMQ控制台XML时需要密码验证，除最后三行外，其余代码均为验证代码，这段代码类似外挂程序，哪里需要验证就放在哪里。
