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;
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;
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;
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;
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;
}
public void setSafe(int safe) {
this.safe = safe;
}
}通用工具类：
package com.toone.itop.formula.function.inte.util;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;

public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
public X509Certificate[] getAcceptedIssuers() {
return null;
}
package com.toone.itop.formula.function.inte.util;

}service层：
package com.toone.itop.formula.function.inte.service;
import net.sf.json.JSONObject;
import com.google.gson.Gson;
import com.toone.itop.formula.function.inte.model.Text;

public class WeChatService {
private static String sendMessage_url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=ACCESS_TOKEN";
public static String sendMessage(String uid, String content) {
// 1.获取access_token:根据企业id和应用密钥获取access_token,并拼接请求url
String accessToken = WeChatUtil.getAccessToken(WeChatParamesUtil.corpId, WeChatParamesUtil.corpsecret).getToken();
// 2.获取发送对象，并转成json
Gson gson = new Gson();
TextMessage message = new TextMessage();
// 1.1非必需
message.setTouser(uid); // 不区分大小写
//message.setToparty("1");
//message.getTouser(totag);
// txtMsg.setSafe(0);
// 1.2必需
message.setMsgtype("text");
message.setAgentid(WeChatParamesUtil.agentId);
Text text = new Text();
text.setContent(content);
message.setText(text);
String jsonMessage = gson.toJson(message);
// 3.获取请求的url
String url = sendMessage_url.replace("ACCESS_TOKEN", accessToken);
// 4.调用接口，发送消息
JSONObject jsonObject = WeChatUtil.httpRequest(url, "POST", jsonMessage);
// 4.错误消息处理
if (null != jsonObject) {
if (0 != jsonObject.getInt("errcode")) {
System.out.println("消息发送失败 errcode:{} errmsg:{}" + jsonObject.getInt("errcode") + jsonObject.getString("errmsg"));
}
}
return jsonObject.toString();
}
public static void main(String[] args) {
// 0.设置消息内容
String content = "这是一条测试消息";
//userId为企业用户的id
String userId = "qianxia";
// 3.发送消息：调用业务类，发送消息
WeChatService.sendMessage(userId, content);
}
}所需引入的依赖
