1.高德地图爬虫爬取数据并插入数据库

//API地址(http://lbs.amap.com/api/webservice/summary/)

publicstatic JSONObject getLngAndLat(Stringaddre, String type){

Stringurl = "http://restapi.amap.com/v3/place/text?parameters&extensions=all&key=1da8ea5d3653cdef862b805333f3465a&output=json&offset=20&page=1&city="+addre+"&keywords="+type; //解析

System.out.println(url);

long startTime1 = System.currentTimeMillis();//获取当前时间

String str = loadJSON(url);

JSONObject obj = JSONObject.fromObject(str);

long endTime1 = System.currentTimeMillis();//结束时间

System.out.println("url"+url);

System.out.println("obj"+obj);

System.out.println("解析程序运行时间"+(endTime1-startTime1)+"ms");

if(obj.get("status").toString().equals("1")){

List<JSONObject> list = obj.getJSONArray("pois");

System.out.println("测试地址集合1"+list);

for(JSONObject jx :list){

String tname = (String)jx.get("name");//名称

String address = (String)jx.get("address");//地址

String location = (String)jx.get("location");//经纬度

String tel = jx.get("tel").toString();//电话

String adname = (String)jx.get("adname"); //所属区名

String cityname = (String)jx.get("cityname"); //所属市名

String citycode = (String)jx.get("citycode"); //市区编码

String adcode = (String)jx.get("adcode"); //区域编码

String typecode = (String)jx.get("typecode"); //兴趣点类型编码

String pname = jx.get("pname").toString(); //所属省份

String pcode = jx.get("pcode").toString(); //省份编码

String postcode =jx.get("postcode").toString(); //邮编

List<Object> photos = (List<Object>) jx.get("photos"); //图片

StringBuffer a = new StringBuffer();

Object photoURL=null;

Scott sc = new Scott();

System.out.println("测试地址集合"+photos);

if(photos.size()==0) {

photoURL="无匹配图片";

sc.setCityname(cityname);

sc.setAdname(adname);

sc.setTname(tname);

sc.setAddress(address);

sc.setLocation(location);

sc.setTel(tel);

sc.setCitycode(citycode);

sc.setAdcode(adcode);

sc.setPcode(pcode);

sc.setPname(pname);

sc.setPostcode(postcode);

sc.setRemark("1");

a.append(photoURL);

a.append(" ");

sc.setTypecode(typecode);

sc.setPhotoURL(a.toString());

}else{

for (Object photo : photos) {

photoURL=((JSONObject)photo).get("url").toString();

sc.setCityname(cityname);

sc.setAdname(adname);

sc.setTname(tname);

sc.setAddress(address);

sc.setLocation(location);

sc.setTel(tel);

sc.setCitycode(citycode);

sc.setAdcode(adcode);

sc.setPcode(pcode);

sc.setPname(pname);

sc.setPostcode(postcode);

sc.setRemark("1");

sc.setTypecode(typecode);

a.append(photoURL);

a.append(" ");

sc.setPhotoURL(a.toString());

}

scottService.saveScottInfo(sc);

}

System.out.println("测试======================"+photoURL);

System.out.println("测试==市名："+cityname+"区名："+adname+"名称："+tname+"地址："+address+"经纬度："+location+"电话："+tel+"城市编码："+citycode+"区域编码："+adcode+"兴趣点类型编码："+typecode+"所属省份："+pname+"所属省份："+pcode+"邮编："+postcode+"图片："+photos);

}

System.out.println("完成");

}

return obj;

}

/**

* 解析地址

publicstatic String loadJSON (String uri) {

StringBuilder json = new StringBuilder();

try {

URL url = new URL(uri);

URLConnection yc =url.openConnection();

BufferedReader in = new BufferedReader(newInputStreamReader(yc.getInputStream(),"utf-8"));

String inputLine = null;

while ( (inputLine = in.readLine()) != null) {

json.append(inputLine);

}

in.close();

} catch (MalformedURLException e) {

} catch (IOException e) {

}

return json.toString();

}

// public static voidmain(String[] args) {

// Scottmap.getLngAndLat("咸阳","酒店");

// }

}

所需jar包{

<artifactId>commons-codec</artifactId>

<version>1.2</version>

</dependency>

<dependency>

}

2.前端点击查看按钮一次显示多张图片（后台返回jsonList集合）

easyui列添加按钮超链接（点击也可跳转网址）

title:'图片操作',

field:'q',

width:80,

formatter:function(){

var btn = "<a class='editcls' id='check-picture' href='javascript:editRow();'>编辑</a>";

return btn;

//前端点击弹出窗口

<div onload="window(close);"id="searchImg"class="easyui-window" title="图片显示窗口" style="width:600px;height:600px"

data-options="iconCls:'icon-save',modal:true,closed:true">

<table>

</tr>

</table>

</div>

</div> }

function editRow(){

if($("#dg").datagrid('getSelections').length==0){

$.messager.show({

title:'查看图片提示',

msg:'请选择要查看的图片',

timeout:5000,

showType:'slide'

})

}elseif($("#dg").datagrid('getSelections').length>1){

$.messager.show({

title:'查看图片提示',

msg:'只能选择一个信息进行查看',

timeout:5000,

showType:'slide'

})

}else {

//获取表单控件的数据

var scottId = $("#dg").datagrid('getSelected').scottId;

$.ajax({

url:"/scott22/scott/searchScottpictureById.do",

type:"post",

data:{"scottId":scottId},

dataType:"json",

//成功返回结果

// success:function(result){

// //跳转到图片页面

// window.open(result.photoUrl);

// }

success:function(data){

var json=eval(data);

var con=""

$.each(json,function(index,photoURL){

var s1=json[index].photoURL;

con+="<td ><img src='"+photoURL+"' width='200px' height='300px'/></td>";

});

;

$("#search").append($("#tr").append(con));

//打开窗口

$("#searchImg").window('open');

}

})

$('#searchImg').window({

onBeforeClose: function () { //当面板关闭之前触发的事件

$('#searchImg').window('close', true); //这里调用close 方法，true 表示面板被关闭的时候忽略onBeforeClose 回调函数。

$('#tr').window('clear');

}

});

}
