####创建service层接口

com\imooc\service\PushMessage.java

package com.imooc.service;

import com.imooc.dto.OrderDTO;

/**

* Created by Administrator on 2020/2/27.

* 微信模板消息推送

*/

public interface PushMessage {

/*订单状态变更消息*/

public void orderStatus(OrderDTO orderDTO);

}

####创建service层实现类

com\imooc\service\imp\PushMessageImp.java

package com.imooc.service.imp;

import com.imooc.config.WechatAccountConfig;

import com.imooc.dto.OrderDTO;

import com.imooc.service.PushMessage;

import lombok.extern.slf4j.Slf4j;

import me.chanjar.weixin.common.exception.WxErrorException;

import me.chanjar.weixin.mp.api.WxMpService;

import me.chanjar.weixin.mp.bean.template.WxMpTemplateData;

import me.chanjar.weixin.mp.bean.template.WxMpTemplateMessage;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import java.util.Arrays;

import java.util.List;

Service

Slf4j

public class PushMessageImp implements PushMessage{

@Autowired

private WxMpService wxMpService;

@Autowired

private WechatAccountConfig accountConfig;

/*订单完结时调用*/

@Override

public void orderStatus(OrderDTO orderDTO) {

/*服务号才会有模板消息 还要服务器加入微信白名单*/

WxMpTemplateMessage templateMessage = new WxMpTemplateMessage();

templateMessage.setTemplateId(accountConfig.getTemplateId().get("orderstatus"));/*模板id*/

templateMessage.setToUser(orderDTO.getBuyerOpenid());/*目标用户的openid*/

List wxMpTemplateDataList = Arrays.asList(

new WxMpTemplateData("first","亲 请记得收货哦！"),

new WxMpTemplateData("keyword1","微信点餐"),

new WxMpTemplateData("keyword2","17600800548"),

new WxMpTemplateData("keyword3",orderDTO.getOrderId()),

new WxMpTemplateData("keyword4",orderDTO.getOrderStatus().toString()),

new WxMpTemplateData("keyword5","￥"+orderDTO.getOrderAmount()),

new WxMpTemplateData("remark","欢迎再次光临")

);

templateMessage.setData(wxMpTemplateDataList);

try{

wxMpService.getTemplateMsgService().sendTemplateMsg(templateMessage);

}catch (WxErrorException e){

log.error("[微信模板异常]");

}

}

}

####把模板id配置到application.yml文件中，并在WechatAccountConfig类中追加属性

wechat:

templateId: #模板消息id

orderstatus: ewur430280238203843

/*微信模板id*/

private Map templateId;

####订单完结时调用

在OrderServiceImp的finish方法中调用消息推送的方法
