Java實(shí)現(xiàn)企業(yè)微信消息推送功能的詳細(xì)步驟
第一步:申請企業(yè)微信注冊企業(yè)(鏈接:https://work.weixin.qq.com/nl/sem/registe?s=c&from=1011017189&bd_vid=11628667012427618020)

第二步:登錄自己的企業(yè)微信找到應(yīng)用管理———>添加應(yīng)用

第三步:獲取到應(yīng)用的AgentId、Secret、企業(yè)id

第四步,準(zhǔn)備代碼編寫:

model層代碼:
package com.toone.itop.formula.function.inte.model;
/**
* @desc : 微信通用接口憑證

*/
public class AccessToken {
// 獲取到的憑證
private String token;
// 憑證有效時間,單位:秒

}
public void setToken(String token) {

public void setExpiresIn(int expiresIn) {
this.expiresIn = expiresIn;
} package com.toone.itop.formula.function.inte.model;
/**

*/
public class BaseMessage {
// 否 成員ID列表(消息接收者,多個接收者用‘|'分隔,最多支持1000個)。特殊情況:指定為@all,則向該企業(yè)應(yīng)用的全部成員發(fā)送
private String touser;
// 否 部門ID列表,多個接收者用‘|'分隔,最多支持100個。當(dāng)touser為@all時忽略本參數(shù)
private String toparty;
// 否 標(biāo)簽ID列表,多個接收者用‘|'分隔,最多支持100個。當(dāng)touser為@all時忽略本參數(shù)
private String totag;
// 是 消息類型
private String msgtype;
// 是 企業(yè)應(yīng)用的id,整型??稍趹?yīng)用的設(shè)置頁面查看
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 消息內(nèi)容,最長不超過2048個字節(jié)
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,默認(rèn)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) {

}
