现在越来越多应用使用地图功能了，目前使用云地图功能调用API实现是比较流行的解决方案。
下面就是高德云地图API使用例子讲解。
首先去高德开发网站注册一个开发者账号，
注册只需要提供手机号和邮箱就可以了。
测试只需要个人开发者，如果商业使用还是申请企业账号吧。
第二步，注册完毕，登陆管理控制台创建自己的应用。
系统默认给一个高德的key，为了更加安全还可以为应用创建一个私有Key
第三步，就可以参考网站的API开发了。下面是工具类代码，引用了一个第三方jar，fastjson-1.1.26.jar，JDK版本是1.8，
package com.meles.gaode;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

如果密钥填写正常，而且tableId写的对的话就可以看到云地图效果了。
自己登录后台管理可以看到如下图：
别人能访问的地图如下图，发布链接： https://yuntu.amap.com/share/zIzeia：
是不是很方便啊。
手机查看地图效果图如下，如果开启定位功能则还有更多功能比如：定位，导航
