参考了一些博客，发现大部分都是通过访问外网再进行获取外网ip，本文是通过访问chinaz的接口返回的ip信息直接获取，有更好的办法可以指教一下，感谢！
package com.platform.api;import java.io.BufferedReader;import java.io.InputStreamReader;import .URL;import .www.protocol.http.HttpURLConnection;/*** @author ajiu*/public class IpUtils {public static String getIP() {// String ip = "/getip.aspx";String ip = "/cityjson?ie=utf-8";String inputLine = "";String read = "";try {URL url = new URL(ip);HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));while ((read = in.readLine()) != null) {inputLine += read;}} catch (Exception e) {e.printStackTrace();}return inputLine;}public static void main(String[] args) {System.out.println(getIP());}}

搜狐接口/cityjson?ie=utf-8(默认GBK，可指定编码)
发现之前的接口已被限制，特在此修改
