我试图从JAVA中的ip地址获取位置信息，但我得到一个JAVA.net.SocketException：连接重置错误

Question

import java.io.IOException;
import java.io.PrintWriter;

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


import javaQuery.importClass.javaQueryBundle;
import javaQuery.j2ee.GeoLocation;
/**
 * Servlet implementation class IP
 */
public class IP extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public IP() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub

         String ipAddress = request.getRemoteAddr();
         System.out.println(ipAddress);

         response.setContentType("text/html;charset=UTF-8");
            PrintWriter out = response.getWriter();


            //Print out the IP address of the caller
            out.println(request.getRemoteAddr());


         GeoLocation $gl = javaQueryBundle.createGeoLocation();

         System.out.println(ipAddress);


            $gl.MAPTargetByIP(ipAddress, "test");
            System.out.println($gl.Latitude);
            System.out.println($gl.Longitude);
            System.out.println($gl.Country);
            System.out.println($gl.City);
            System.out.println($gl.State);
            System.out.println($gl.GoogleMap_URL);
            System.out.println($gl.GoogleMap_URL_Bubble);


    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

}

这是我的代码片段。我得到的是访客的IP地址，但不是位置信息。它给出：java.net.SocketException：连接重置在java.net.SocketInputStream.Read（未知源）在java.net.SocketInputStream.Read（未知源）

要告诉java代码所有HTTP请求都应该通过代理路由，请使用以下代码段：

System.SetProperty（“http.ProxyHost”,“ProxyHost”）；System.SetProperty（“http.ProxyPort”,“ProxyPort”）；Authenticator Authenticator=new Authenticator（）{public PasswordAuthentication getPasswordAuthentication（）{return（new PasswordAuthentication（“username”,“password”.toCharArray（）））；}}；authenticator.SetDefault（authenticator）；

System.SetProperty设置代理主机和端口。身份验证器应该是您的公司用户名和密码。现在应该管用了。
