微信点餐之微信模板（12）

https://mp.weixin.qq.com/ 模板消息

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;

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<WxMpTemplateData> 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<String,String> templateId;

订单完结时调用

在OrderServiceImp的finish方法中调用消息推送的方法
