第一步:申请企业微信注册企业(链接:https://work.weixin.qq.com/nl/sem/registe?s=c&from=1011017189&bd_vid=11628667012427618020)
第二步:登录自己的企业微信找到应用管理———>添加应用
第三步:获取到应用的AgentId、Secret、企业id
第四步,准备代码编写:
model层代码:
package com.toone.itop.formula.function.inte.model;
/**
* @desc : 微信通用接口凭证
*
*/
public class AccessToken {
// 获取到的凭证
private String token;
// 凭证有效时间,单位:秒
private int expiresIn;
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
public int getExpiresIn() {
return expiresIn;
}
public void setExpiresIn(int expiresIn) {
this.expiresIn = expiresIn;
}
}
package com.toone.itop.formula.function.inte.model;
/**
* 消息基类(企业号 -> 普通用户)
*
*/
public class BaseMessage {
// 否 成员ID列表(消息接收者,多个接收者用‘|’分隔,最多支持1000个)。特殊情况:指定为@all,则向该企业应用的全部成员发送
private String touser;
// 否 部门ID列表,多个接收者用‘|’分隔,最多支持100个。当touser为@all时忽略本参数
private String toparty;
// 否 标签ID列表,多个接收者用‘|’分隔,最多支持100个。当touser为@all时忽略本参数
private String totag;
// 是 消息类型
private String msgtype;
// 是 企业应用的id,整型。可在应用的设置页面查看
private int agentid;
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 int getAgentid() {
return agentid;
}
public void setAgentid(int agentid) {
this.agentid = agentid;
}
}
package com.toone.itop.formula.function.inte.model;
/**
* 文本
*
*/
public class Text {
//是 消息内容,最长不超过2048个字节
private String content;
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}
package com.toone.itop.formula.function.inte.model;
/**
* 文本消息
*
*/
public class TextMessage extends BaseMessage {
// 文本
private Text text;
// 否 表示是否是保密消息,0表示否,1表示是,默认0
private int safe;
public Text getText() {
return text;
}
public void setText(Text text2) {
this.text = text2;
}
public int getSafe() {
return safe;
}

}
