申请后需要在管理平台做如下几个步骤:
1、在通讯录里添加一个成员并使这个成员关注这个微信企业号；
2、在应用中心里新建一个应用并记录appid；
3、在设置里的权限管理中新建管理组；
新建一个JavaWeb工程并导入如下几个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工程的代码如下：

}
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文件内容如下:
package com.shihuan.pojo;
import java.io.Serializable;
public class Text implements Serializable {
private String content;
public Text() {
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}
MsgTypeAndDataFormat.java文件内容如下:
package com.shihuan.pojo;
import java.io.Serializable;
public class MsgTypeAndDataFormat implements Serializable {
private String touser;

private String msgtype;
private String agentid;
private Text text;
private String safe;
public MsgTypeAndDataFormat() {
}
public String getTouser() {
return touser;
}
public void setTouser(String touser) {
this.touser = touser;
}
public String getToparty() {
return toparty;
}
public void setToparty(String toparty) {
this.toparty = toparty;
}
public String getTotag() {
return totag;
}
public void setTotag(String totag) {
this.totag = totag;
}
public String getMsgtype() {
return msgtype;
}
public void setMsgtype(String msgtype) {
this.msgtype = msgtype;
}
public String getAgentid() {
return agentid;
}
public void setAgentid(String agentid) {
this.agentid = agentid;
}
public Text getText() {
return text;
}
public void setText(Text text) {
this.text = text;
}
public String getSafe() {
return safe;
}
public void setSafe(String safe) {
this.safe = safe;
}
}
