這篇文章主要介紹了Java微信開發(fā)中使用XML格式和JSON格式數(shù)據(jù)的示例,注意一下json-lib所需要的jar包,需要的朋友可以參考下

XML微信XML消息model定義：

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?2014年5月21日下午2:13:27
?*/
public?class?XMLMsg?{
//普通消息基本變量
?String?ToUserName;
?String?FromUserName;
?String?CreateTime;
?String?MsgType;
?String?Content;
?String?MsgId;
//事件推送變量
?String?Event;
//自定義菜單項(xiàng)
?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
這里我們使用json-lib，注意一下需要以下幾個(gè)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

以下是簡(jiǎn)單的AccessToken類，返回String類型的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?{
?
?/**
??*?根據(jù)注冊(cè)信息，獲得的參數(shù)，提交get請(qǐng)求，獲得accessTkoen
??*?@author?lpe234
??*?@time?2014-5-21?00:52:15
??*/
?String?appID?=?"XXXXXXXXXXXXXX";
?String?appsecret?=?"XXXXXXXXXXXXXXXXX";//微信服務(wù)號(hào)或者申請(qǐng)測(cè)試賬號(hào)的訂閱號(hào)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);
/**?測(cè)試
*?public?static?void?main(String[]?args)?{
*??AccessToken?as?=?new?AccessToken();
*??System.out.println(as.get());
*?}
*/
?//返回String類型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;
?}
?
?//?獲取wx服務(wù)器返回JSON數(shù)據(jù),private內(nèi)部調(diào)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;
?}
}

額 大體就是這樣
