Examples of Java micro-credit development using XML format and JSON format data _java

XML
micro-letter XML message Model definition:

Package cn.wx.server;
Import org.dom4j.Document;
Import org.dom4j.DocumentException;
Import Org.dom4j.DocumentHelper;
 
Import org.dom4j.Element;  /** * @title Cn.wx.serverXMLMsg.java * @todo todo * @author lpe234 * @time May 21, 2014 afternoon 2:13:27 * * public class Xmlmsg
 {//Normal message basic variable String tousername;
 String Fromusername;
 String Createtime;
 String Msgtype;
 String Content;
String MsgId;
Event push variable String event;
  
 
 Custom menu item String eventkey;
 Public String Geteventkey () {return eventkey;
 } public void Seteventkey (String eventkey) {eventkey = Eventkey;
  Public xmlmsg (String str) throws Documentexception {Document doc = Documenthelper.parsetext (str);
  Element root = Doc.getrootelement (); This.
  Tousername = Root.elementtext ("Tousername"); This.
  Fromusername = Root.elementtext ("Fromusername"); This.
  Createtime = Root.elementtext ("Createtime"); This.
  Msgtype = Root.elementtext ("Msgtype"); This.
  Content = Root.elementtext ("content"); This. MsgId = Root.elementtExt ("MsgId"); This.
  event = Root.elementtext ("event"); This.
 Eventkey = Root.elementtext ("Eventkey");
 Public String getEvent () {return Event;
 public void SetEvent (String event) {event = event;
 Public String Gettousername () {return tousername;
 } public void Settousername (String tousername) {tousername = Tousername;
 Public String Getfromusername () {return fromusername;
 } public void Setfromusername (String fromusername) {fromusername = Fromusername;
 Public String Getcreatetime () {return createtime;
 } public void Setcreatetime (String createtime) {createtime = Createtime;
 Public String Getmsgtype () {return msgtype;
 } public void Setmsgtype (String msgtype) {msgtype = Msgtype;
 Public String getcontent () {return Content;
 public void SetContent (String content) {content = content;
 Public String Getmsgid () {return MsgId;
 } public void Setmsgid (String msgId) {msgId = MsgId;
}}
 

Json
Here we use Json-lib, and note that we need support for the following jar packages:

• Json-lib-2.4-jdk15.jar
• Commons-logging-1.1.3.jar
• Ezmorph-1.0.6.jar
• Commons-lang-2.4.jar
• Commons-collections.jar
• Commons-beanutils-1.8.0.jar

The following is a simple Accesstoken class that returns the string type of Access_token

Package cn.wx.server;
Import Java.io.BufferedReader;
Import java.io.IOException;
Import Java.io.InputStreamReader;
Import java.net.MalformedURLException;
Import Java.net.URL;
 
Import java.net.URLConnection;
 
Import Net.sf.json.JSONObject;
  public class Accesstoken {/** * According to the registration information, obtain the parameters, submit GET request, obtain Accesstkoen * @author lpe234 * @time 2014-5-21 00:52:15
 */String AppID = "xxxxxxxxxxxxxx";
 String Appsecret = "xxxxxxxxxxxxxxxxx";//micro-letter service number or the subscription number of the application test account only ... String Preurl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s"
 ;
String Tempurl = String.Format (Preurl, AppID, Appsecret);
/** Test * public static void Main (string[] args) {* Accesstoken as = new Accesstoken (); * SYSTEM.OUT.PRINTLN (As.get ());
  *///return String type Access_token public string get () {string temp = null;
  temp = Getjson ();
  Jsonobject j = jsonobject.fromobject (temp);
  temp = j.getstring ("Access_token");
  SYSTEM.OUT.PRINTLN (temp);
 return temp; }
 
 //Get WX server to return JSON data, private internal call private string Getjson () {string temp = null;
   try {URL url = new URL (tempurl);
   URLConnection conn = Url.openconnection ();
   InputStreamReader ISR = new InputStreamReader (Conn.getinputstream ());
   BufferedReader br = new BufferedReader (ISR);
  temp = Br.readline ();
  catch (Malformedurlexception e) {//TODO auto-generated catch block E.printstacktrace ();
  catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
  //SYSTEM.OUT.PRINTLN (temp);
 return temp;
 }
}

The amount is roughly the same
