微信给关注公众号的用户推送模板消息

1.在公众号后台获取消息模板（本例使用微信测试账号），观看微信官方文档：https://developers.weixin.qq.com/doc/offiaccount/Message_Management/Template_Message_Interface.html#5

 测试账号需自己定义消息模板：

{{first.DATA}}
商家名称：{{keyword1.DATA}}
商家电话：{{keyword2.DATA}}
订单号：{{keyword3.DATA}}
状态：{{keyword4.DATA}}
总价：{{keyword5.DATA}}
{{remark.DATA}}

2.使用sdk，编写微信推送模板消息的service

@Service
@Slf4j
public class PushMessageServiceImpl implements PushMessageService {

    @Autowired
    private WxMpService wxMpService;
    @Autowired
    private WechatAccountConfig accountConfig;
    @Override
    public void pushMessage(OrderDTO orderDTO) {
        //新建模板消息类
        WxMpTemplateMessage wxMpTemplateMessage=new WxMpTemplateMessage();
        //编写模板消息需推送的用户，该用户必须关注了公众号
        wxMpTemplateMessage.setToUser("owRHRv5J3oiMbb8D7_YYSvXvngiw");
        //配置推送消息模板id
        wxMpTemplateMessage.setTemplateId(accountConfig.getTemplateId().get("orderStatus"));
        //配置推送消息的内容
        List<WxMpTemplateData> data= Arrays.asList(
                new WxMpTemplateData("first","用餐愉快哦"),
                new WxMpTemplateData("keyword1","微信点餐"),
                new WxMpTemplateData("keyword2","13826913333"),
                new WxMpTemplateData("keyword3",orderDTO.getOrderId()),
                new WxMpTemplateData("keyword4",orderDTO.getOrderStatusEnum().getMsg()),
                new WxMpTemplateData("keyword5","￥"+orderDTO.getOrderAmount()),
                new WxMpTemplateData("remark","用餐愉快哦")
        );
        wxMpTemplateMessage.setData(data);
        try {
            //使用sdk发送模板消息
            String msg = wxMpService.getTemplateMsgService().sendTemplateMsg(wxMpTemplateMessage);
            log.info("发送模板消息返回的信息为：{}",msg);
        } catch (WxErrorException e) {
            e.printStackTrace();
        }
    }
}

3.结果如下：
