首先到微信公众平台申请微信企业号: https://qy.weixin.qq.com
申请后须要在管理平台作以下几个步骤:
一、在通信录里添加一个成员并使这个成员关注这个微信企业号;
二、在应用中内心新建一个应用并记录appid;
三、在设置里的权限管理中新建管理组;
新建一个JavaWeb工程并导入以下几个jar文件:
commons-logging-1.1.1.jar,fastjson-1.2.7.jar,httpclient-4.5.1.jar,httpcore-4.4.3.jar,weixin-java-cp-1.3.1.jar
下载jquery-2.1.4.min.js文件并添加到JavaWeb工程中。
JavaWeb工程的代码以下:

}
public void setAccess_token(String accessToken) {
access_token = accessToken;
}
public String getExpires_in() {
return expires_in;
}
public void setExpires_in(String expiresIn) {
expires_in = expiresIn;
}
}
Text.java文件内容以下:

}
public void setContent(String content) {
this.content = content;
}
}
MsgTypeAndDataFormat.java文件内容以下:

}
public void setAgentid(String agentid) {
this.agentid = agentid;
}
public Text getText() {
return text;
