xml
微信xml消息model定义:

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

 */
public class xmlmsg {
//普通消息基本变量
 string tousername;
 string fromusername;
 string createtime;
 string msgtype;
 string content;
 string msgid;
//事件推送变量
 string event;
//自定义菜单项
 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");

}


json
这里我们使用json-lib,注意一下需要以下几个jar包的支持:

  • 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

以下是简单的accesstoken类,返回string类型的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 {
 
 /**
  * 根据注册信息,获得的参数,提交get请求,获得accesstkoen
  * @author lpe234
  * @time 2014-5-21 00:52:15
  */
 string appid = "xxxxxxxxxxxxxx";
 string appsecret = "xxxxxxxxxxxxxxxxx";//微信服务号或者申请测试账号的订阅号才有。。。
 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);
/** 测试
* public static void main(string[] args) {
*  accesstoken as = new accesstoken();
*  system.out.println(as.get());
* }
*/
 //返回string类型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;
 }
 
 // 获取wx服务器返回json数据,private内部调用
 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;
 }
}

额 大体就是这样
