1、數據接收接口：
這個可以考慮最簡單的Servlet方法，而且效率較高；
import java.io.PrintWriter;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Enumeration;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.google.gson.Gson;
import com.hgh.receive.Receive;
import com.hgh.receive.ReturnJson;
public class kdniaoLogistics2 extends HttpServlet{
private Gson gson=new Gson();
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
doPost(req, resp);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
Enumeration<String> list = req.getParameterNames(); //這個主要是為了從一個數據結構得到連續數據
Receive re = null;
while (list.hasMoreElements()) {
String str = (String) list.nextElement(); //獲取參數名稱
String str1=req.getParameter(str); //獲取對應參數名稱的內容
f(str.equals("RequestData")){ //此處是判斷參數名稱
re = gson.fromJson(str1, Receive.class); //gson字符串轉為對象；這個類非常的好用，強力推薦
LinkQueue.getLinkQueue().add(re); //這兩個都是對參數和參數名的操作，我是采用隊列形式存儲參數，解決對方傳參數量過大，且速度快導致系統接收不全
//這個只需要對象的操作，如需隊列相關的操作請見下一博客；
}
}
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
PrintWriter fs = resp.getWriter(); //准備返回接收信息
ReturnJson returnjson; //返回參數對象，按API文檔定義
if(re!=null){ //判斷接收到的信息轉為對象后有沒有值，或者有沒有正常的接收到數據
returnjson = new ReturnJson("1282148",sdf.format(new Date()), "true", "");
System.out.println(gson.toJson(returnjson));//將對象轉成JSON輸出
}else{
returnjson = new ReturnJson("1282148",sdf.format(new Date()), "false", "未能有效接收到數據");
System.out.println(gson.toJson(returnjson));
}
fs.write(gson.toJson(returnjson)); //直接返回信息
}
}
