通过google map批量进行地址解析成坐标
public static void main(String args[]){
Thread thread=new Thread();
List list=new ArrayList();//list中存放的是要查询的地址
for(int i=0;i<list.size();i++){
String address=list.get(i);
String ss=URLEncoder.encode(address,"UTF-8");//对地址进行编码
thread.sleep(5000);//要等待几秒中,如果查询速度太快,google地图会查询不出来,严重会封ip
String mess=sendGet("http://ditu.google.cn/maps/geo", "output=csv&key=abcdef&q="+ss);
//上边是通过ouput=csv输出的,还有json,xml等形式(如果需要可以查看谷歌地图中介绍,另一篇地址解析文章中有地址)
System.out.println(mess);
}
}
public static String sendGet(String url, String param) {
String result = "";
BufferedReader in = null;
try {
String urlName = url + "?" + param;
URL realUrl = new URL(urlName);
// 打开和URL之间的连接
URLConnection conn = realUrl.openConnection();
// 设置通用的请求属性
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
// 建立实际的连接
conn.connect();
// 获取所有响应头字段
Map map = conn.getHeaderFields();
// 遍历所有的响应头字段
for (String key : map.keySet()) {
// System.out.println(key + "--->" + map.get(key));
}
// 定义BufferedReader输入流来读取URL的响应
in = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
System.out.println("发送GET请求出现异常!" + e);
e.printStackTrace();
}
// 使用finally块来关闭输入流
finally {
try {
if (in != null) {
in.close();
}
} catch (IOException ex) {
ex.printStackTrace();

return result;
