先声明一下,这是一个maven工程
pom文件需要的依赖:
1 <dependency> 2 <groupId>dom4j</groupId> 3 <artifactId>dom4j</artifactId> 4 <version>1.6</version> 5 </dependency> 6 <dependency> 7 <groupId>commons-io</groupId> 8 <artifactId>commons-io</artifactId> 9 <version>2.5</version> 10 </dependency> 11 <dependency> 12 <groupId>com.thoughtworks.xstream</groupId> 13 <artifactId>xstream</artifactId> 14 <version>1.4.9</version> 15 </dependency> 16 <dependency> 17 <groupId>javax.servlet</groupId> 18 <artifactId>javax.servlet-api</artifactId> 19 <version>3.1.0</version> 20 </dependency>
微信消息都是基于xml文件进行接收发送的
微信文本消息的参数:
<xml> <ToUserName><![CDATA[toUser]]></ToUserName> <FromUserName><![CDATA[fromUser]]></FromUserName> <CreateTime>1348831860</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content><![CDATA[this is a test]]></Content> <MsgId>1234567890123456</MsgId> </xml> <!--参数 描述 ToUserName 开发者微信号 FromUserName 发送方帐号(一个OpenID) CreateTime 消息创建时间 (整型) MsgType text Content 文本消息内容 MsgId 消息id,64位整型 -->
微信回复文本消息的参数
<xml>
<ToUserName><![CDATA[toUser]]></ToUserName>
<FromUserName><![CDATA[fromUser]]></FromUserName>
<CreateTime>12345678</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[你好]]></Content>
</xml>
<!--参数 是否必须 描述
ToUserName 是 接收方帐号(收到的OpenID)
FromUserName 是 开发者微信号
CreateTime 是 消息创建时间 (整型)
MsgType 是 text
Content 是 回复的消息内容(换行:在content中能够换行,微信客户端就支持换行显示)
-->
我会在相应的代码上加上注释,其他对应图片消息参数,以及回复图片消息参数、图文消息参数等等 请参考微信开发文档。
附上微信公众号接口文档链接:点击这里
二话不说 先附上主代码:
注: xml解析:本文使用的是xtream进行xml与java对象之间的转换;对于xml解析还可以使用其他方法 如:dom4j等等 我这里就不一一列举了

当你看到这里 说明你成功一半了,下面我们继续来完成这些小瑕疵
这时候需要:根据xml标签创建对应的实体类
实体类一:音乐消息
import com.util.Music; /** * 音乐消息实体类 */ public class ReplyMusicMessage { private String toUserName; private String fromUserName; private String createTime; private String messageType; private com.util.Music Music; private String funcFlag; //这里的funcFlag,微信平台接口文档里没有,但是必须写上,不然会收不到返回的信息 public String getToUserName() { return toUserName; } public void setToUserName(String toUserName) { this.toUserName = toUserName; } public String getFromUserName() { return fromUserName; } public void setFromUserName(String fromUserName) { this.fromUserName = fromUserName; } public String getCreateTime() { return createTime; } public void setCreateTime(String createTime) { this.createTime = createTime; } public String getMessageType() { return messageType; } public void setMessageType(String messageType) { this.messageType = messageType; } public Music getMusic() { return Music; } public void setMusic(Music music) { Music = music; } public String getFuncFlag() { return funcFlag; } public void setFuncFlag(String funcFlag) { this.funcFlag = funcFlag; } }
实体类二:文本消息(常用)
/** * 文本消息实体类 */ public class ReplyTextMessage { private String toUserName; private String fromUserName; private String createTime; private String messageType; private String content; private String funcFlag; public String getToUserName() { return toUserName; } public void setToUserName(String toUserName) { this.toUserName = toUserName; } public String getFromUserName() { return fromUserName; } public void setFromUserName(String fromUserName) { this.fromUserName = fromUserName; } public String getCreateTime() { return createTime; } public void setCreateTime(String createTime) { this.createTime = createTime; } public String getMessageType() { return messageType; } public void setMessageType(String messageType) { this.messageType = messageType; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public String getFuncFlag() { return funcFlag; } public void setFuncFlag(String funcFlag) { this.funcFlag = funcFlag; } }
实体类三:图文消息(常用)
import com.util.Articles; /** * 图文消息实体类 */ public class ReplyTuwenMessage { private String toUserName; private String fromUserName; private String createTime; private String messageType; private int articleCount; private Articles articles; private String funcFlag; public String getToUserName() { return toUserName; } public void setToUserName(String toUserName) { this.toUserName = toUserName; } public String getFromUserName() { return fromUserName; } public void setFromUserName(String fromUserName) { this.fromUserName = fromUserName; } public String getCreateTime() { return createTime; } public void setCreateTime(String createTime) { this.createTime = createTime; } public String getMessageType() { return messageType; } public void setMessageType(String messageType) { this.messageType = messageType; } public int getArticleCount() { return articleCount; } public void setArticleCount(int articleCount) { this.articleCount = articleCount; } public Articles getArticles() { return articles; } public void setArticles(Articles articles) { this.articles = articles; } public String getFuncFlag() { return funcFlag; } public void setFuncFlag(String funcFlag) { this.funcFlag = funcFlag; } }
请求消息实体类
/** * 请求消息实体类 */ public class RequestTextMessage { private String toUserName; private String fromUserName; private String createTime; private String messageType; private String content; private String msgId; //getters,setters public String getToUserName() { return toUserName; } public void setToUserName(String toUserName) { this.toUserName = toUserName; } public String getFromUserName() { return fromUserName; } public void setFromUserName(String fromUserName) { this.fromUserName = fromUserName; } public String getCreateTime() { return createTime; } public void setCreateTime(String createTime) { this.createTime = createTime; } public String getMessageType() { return messageType; } public void setMessageType(String messageType) { this.messageType = messageType; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public String getMsgId() { return msgId; } public void setMsgId(String msgId) { this.msgId = msgId; } }
音乐消息实体类
/** * 音乐消息实体类 */ public class Music { private String title; private String description; private String musicUrl; private String hqMusicUrl; //getters,setters public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getMusicUrl() { return musicUrl; } public void setMusicUrl(String musicUrl) { this.musicUrl = musicUrl; } public String getHqMusicUrl() { return hqMusicUrl; } public void setHqMusicUrl(String hqMusicUrl) { this.hqMusicUrl = hqMusicUrl; } }
xml嵌套标签实体类
/** * xml嵌套标签实体类 */ public class Articles { private Item item; public Item getItem() { return item; } public void setItem(Item item) { this.item = item; } }
xml嵌套标签实体类
/** * xml嵌套标签实体类 */ public class Item { private String title; private String description; private String picUrl; private String url; public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getPicUrl() { return picUrl; } public void setPicUrl(String picUrl) { this.picUrl = picUrl; } public String getUrl() { return url; } public void setUrl(String url) { this.url = url; } }
当你看到这里 恭喜你 微信公众号自动回复的基础操作你已经学会了
后续还会有 在公众号基础上进行小活动开发 后续更新...
