hightmaps 按地图上显示的统计数据

离extjs 至 easyui 到html5到hightchars 再到hightmaps。Exjts和easyui很相似，extjs是重量级的，easyui轻量级的。比extjs容易上手。照着demo改就能够开发了。easyui入门demo见：easyui-demo，或者到官网http://www.jeasyui.com/；会了easyui开发，上手html5界面开发也很的快。大多类似的。到html5-demo界面开发下载demo 然后把demo放到自己的web项目中或者訪问http://www.rgraph.net/docs/line.html。进一步使用hightchar也很容易，下载demo体验一下hightchar很方便地样例，理解hightchar，官网http://www.highcharts.com/或见hightchars-demo

以下介绍hightmap开发中国地图分布量，效果截图。

Action代码

package com.li72.action;import com.li72.dao.MapDao;
import com.opensymphony.xwork2.ActionSupport;/*** @author 一个简单的前后台交换 地图展示**/
public class MapAction extends ActionSupport{private static final long serialVersionUID = -5452039838295753607L;MapDao map= new MapDao();private String data;public String  chinaMap(){data = map.mkData();return SUCCESS;}public String getData() {return data;}public void setData(String data) {this.data = data;}
}

dao层，产生模拟数据。建议把地图做成通用的，仅仅要把数据源改变，就能够产生不同的按地区分布图。

package com.li72.dao;import java.util.HashMap;
import java.util.Map;
import java.util.Random;public class MapDao {/*** @return  依照地图的设定，对这些省市进行设值*/public String  mkData(){StringBuffer sb = new StringBuffer("");Map<String,String> myMap= new HashMap<String,String>(40);myMap.put("吉林省","cn-jl");        myMap.put("天津市","cn-tj");        myMap.put("安徽省","cn-ah");        myMap.put("山东省","cn-sd");        myMap.put("山西省","cn-sx");        myMap.put("新疆维吾尔自治区","cn-xj");myMap.put("河北省","cn-hb");        myMap.put("河南省","cn-he");        myMap.put("湖南省","cn-hn");        myMap.put("甘肃省","cn-gs");        myMap.put("福建省","cn-fj");        myMap.put("贵州省","cn-gz");        myMap.put("重庆市","cn-cq");        myMap.put("江苏省","cn-js");        myMap.put("湖北省","cn-hu");        myMap.put("内蒙古自治区","cn-nm");  myMap.put("广西壮族自治区","cn-gx"); myMap.put("黑龙江省","cn-hl");      myMap.put("云南省","cn-yn");        myMap.put("辽宁省","cn-ln");        myMap.put("香港特别行政区","cn-6668"); myMap.put("浙江省","cn-zj");        myMap.put("上海市","cn-sh");        myMap.put("北京市","cn-bj");        myMap.put("广东省","cn-gd");        myMap.put("澳门特别行政区","cn-3681"); myMap.put("西藏自治区","cn-xz");    myMap.put("陕西省","cn-sa");        myMap.put("四川省","cn-sc");        myMap.put("海南省","cn-ha");        myMap.put("宁夏回族自治区","cn-nx"); myMap.put("青海省","cn-qh");        myMap.put("江西省","cn-jx");        myMap.put("台湾省","tw-tw");        //  {"hc-key": "cn-sh","value": 0},Random random = new Random();String value="";for (Object o : myMap.keySet()) { value= random.nextInt(100)+1+"" ;sb.append("{'hc-key':'").append(myMap.get(o)).append("','value':").append(value).append("},").append("\n");;}return  sb.deleteCharAt(sb.length()-1)+"";}

Struts2配置

<package name="li72" extends="struts-default">
<action name="chinaMap" class="com.li72.action.MapAction" method="chinaMap">
<result name="success">/china-map.jsp</result>
</action>
</package>
