微信聊天页面java代码 java实现聊天框
Java怎样实现类似Android/IOS短信界面 微信聊天 QQ空间回复那样一左一右的气泡式 界面该怎样布局
其实就是两个布局,里面头像,对话框控件的android:id一样,然后再adapter中getview()根据用户判断选择不同的加载就OK了,代码类似于

如何用java开发微信
说明:
本次的教程主要是对微信公众平台开发者模式的讲解,网络上很多类似文章,但很多都让初学微信开发的人一头雾水,所以总结自己的微信开发经验,将微信开发的整个过程系统的列出,并对主要代码进行讲解分析,让初学者尽快上手。
在阅读本文之前,应对微信公众平台的官方开发文档有所了解,知道接收和发送的都是xml格式的数据。另外,在做内容回复时用到了图灵机器人的api接口,这是一个自然语言解析的开放平台,可以帮我们解决整个微信开发过程中最困难的问题,此处不多讲,下面会有其详细的调用方式。
1.1 在登录微信官方平台之后,开启开发者模式,此时需要我们填写url和token,所谓url就是我们自己服务器的接口,用WechatServlet.java来实现,相关解释已经在注释中说明,代码如下:
[java] view plain copy
package demo.servlet;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import demo.process.WechatProcess;
/**
* 微信服务端收发消息接口
*
* @author pamchen-1
*
*/
public class WechatServlet extends HttpServlet {
/**
* The doGet method of the servlet. br
*
* This method is called when a form has its tag value method equals to get.
*
* @param request
* the request send by the client to the server
* @param response
* the response send by the server to the client
* @throws ServletException
* if an error occurred
* @throws IOException
* if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
/** 读取接收到的xml消息 */
StringBuffer sb = new StringBuffer();
InputStream is = request.getInputStream();
InputStreamReader isr = new InputStreamReader(is, "UTF-8");
BufferedReader br = new BufferedReader(isr);
String s = "";
while ((s = br.readLine()) != null) {
sb.append(s);
}
String xml = sb.toString(); //次即为接收到微信端发送过来的xml数据
String result = "";
/** 判断是否是微信接入激活验证,只有首次接入验证时才会收到echostr参数,此时需要把它直接返回 */
String echostr = request.getParameter("echostr");
if (echostr != null echostr.length() 1) {
result = echostr;
} else {
//正常的微信处理流程
result = new WechatProcess().processWechatMag(xml);
}
try {
OutputStream os = response.getOutputStream();
os.write(result.getBytes("UTF-8"));
os.flush();
os.close();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* The doPost method of the servlet. br
*
* This method is called when a form has its tag value method equals to
* post.
*
* @param request
* the request send by the client to the server
* @param response
* the response send by the server to the client
* @throws ServletException
* if an error occurred
* @throws IOException
* if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
1.2 相应的web.xml配置信息如下,在生成WechatServlet.java的同时,可自动生成web.xml中的配置。前面所提到的url处可以填写例如:http;//服务器地址/项目名/wechat.do
[html] view plain copy
?xml version="1.0" encoding="UTF-8"?
web-app version="2.5"
xmlns=""
xmlns:xsi=""
xsi:schemaLocation="
"

display-nameThis is the display name of my J2EE component/display-name
servlet-nameWechatServlet/servlet-name

url-pattern/wechat.do/url-pattern

welcome-fileindex.jsp/welcome-file
/welcome-file-list
/web-app
1.3 通过以上代码,我们已经实现了微信公众平台开发的框架,即开通开发者模式并成功接入、接收消息和发送消息这三个步骤。
下面就讲解其核心部分——解析接收到的xml数据,并以文本类消息为例,通过图灵机器人api接口实现智能回复。
2.1 首先看一下整体流程处理代码,包括:xml数据处理、调用图灵api、封装返回的xml数据。
[java] view plain copy
package demo.process;
import java.util.Date;
import demo.entity.ReceiveXmlEntity;
/**
* 微信xml消息处理流程逻辑类
* @author pamchen-1
*
*/
public class WechatProcess {
/**
* 解析处理xml、获取智能回复结果(通过图灵机器人api接口)
* @param xml 接收到的微信数据
* @return 最终的解析结果(xml格式数据)
*/
public String processWechatMag(String xml){
/** 解析xml数据 */
ReceiveXmlEntity xmlEntity = new ReceiveXmlProcess().getMsgEntity(xml);
/** 以文本消息为例,调用图灵机器人api接口,获取回复内容 */
String result = "";
if("text".endsWith(xmlEntity.getMsgType())){
result = new TulingApiProcess().getTulingResult(xmlEntity.getContent());
}
/** 此时,如果用户输入的是“你好”,在经过上面的过程之后,result为“你也好”类似的内容
* 因为最终回复给微信的也是xml格式的数据,所有需要将其封装为文本类型返回消息
* */
result = new FormatXmlProcess().formatXmlAnswer(xmlEntity.getFromUserName(), xmlEntity.getToUserName(), result);
return result;
}
}
2.2 解析接收到的xml数据,此处有两个类,ReceiveXmlEntity.java和ReceiveXmlProcess.java,通过反射的机制动态调用实体类中的set方法,可以避免很多重复的判断,提高代码效率,代码如下:
[java] view plain copy
package demo.entity;
/**
* 接收到的微信xml实体类
* @author pamchen-1
*
*/
public class ReceiveXmlEntity {
private String ToUserName="";
private String FromUserName="";
private String CreateTime="";
private String MsgType="";
private String MsgId="";
private String Event="";
private String EventKey="";
private String Ticket="";
private String Latitude="";
private String Longitude="";
private String Precision="";
private String PicUrl="";
private String MediaId="";
private String Title="";
private String Description="";
private String Url="";
private String Location_X="";
private String Location_Y="";
private String Scale="";
private String Label="";
private String Content="";
private String Format="";
private String Recognition="";
public String getRecognition() {
return Recognition;
}
public void setRecognition(String recognition) {
Recognition = recognition;
}
public String getFormat() {
return Format;
}
public void setFormat(String format) {
Format = format;
}
public String getContent() {
return Content;
}
public void setContent(String content) {
Content = content;
}
public String getLocation_X() {
return Location_X;
}
public void setLocation_X(String locationX) {
Location_X = locationX;
}
public String getLocation_Y() {
return Location_Y;
}
public void setLocation_Y(String locationY) {
Location_Y = locationY;
}
public String getScale() {
return Scale;
}
public void setScale(String scale) {
Scale = scale;
}
public String getLabel() {
return Label;
}
public void setLabel(String label) {
Label = label;
}
public String getTitle() {
return Title;
}
public void setTitle(String title) {
Title = title;
}
public String getDescription() {
return Description;
}
public void setDescription(String description) {
Description = description;
}
public String getUrl() {
return Url;
}
public void setUrl(String url) {
Url = url;
}
public String getPicUrl() {
return PicUrl;
}
public void setPicUrl(String picUrl) {
PicUrl = picUrl;
}
public String getMediaId() {
return MediaId;
}
public void setMediaId(String mediaId) {
MediaId = mediaId;
}
public String getEventKey() {
return EventKey;
}
public void setEventKey(String eventKey) {
EventKey = eventKey;
}
public String getTicket() {
return Ticket;
}
public void setTicket(String ticket) {
Ticket = ticket;
}
public String getLatitude() {
return Latitude;
}
public void setLatitude(String latitude) {
Latitude = latitude;
}
public String getLongitude() {
return Longitude;
}
public void setLongitude(String longitude) {
Longitude = longitude;
}
public String getPrecision() {
return Precision;
}
public void setPrecision(String precision) {
Precision = precision;
}
public String getEvent() {
return Event;
}
public void setEvent(String event) {
Event = event;
}
public String getMsgId() {
return MsgId;
}
public void setMsgId(String msgId) {
MsgId = msgId;
}
public String getToUserName() {
return ToUserName;
}
public void setToUserName(String toUserName) {
java实现微信发送消息
net的我有 java的还没看呢 给你说说原理 通过开发者id 或者关注者列表 然后通过用户openid(用户唯一标示)向用户发送客服消息 他这个通道是走的客服消息 ,前提是必须关注者主动向公众号发过消息 时限为24h
