　　配置文件

@Data
@Component
@ConfigurationProperties(prefix = "wechat")
public class WechatAccountConfig {

    
    /**
     * 微信模版id

1.创建service

public interface PushMessageService {

    /**
     * 订单状态变更消息
     * @param orderDTO
     */
    void orderStatus(OrderDTO orderDTO);
}

　　2.实现service

@Service
@Slf4j
public class PushMessageServiceImpl implements PushMessageService {

    @Autowired
    private WxMpService wxMpService;

    @Autowired
    private WechatAccountConfig accountConfig;

    @Override
    public void orderStatus(OrderDTO orderDTO) {
        WxMpTemplateMessage templateMessage = new WxMpTemplateMessage();
        templateMessage.setTemplateId(accountConfig.getTemplateId().get("orderStatus"));
        templateMessage.setToUser(orderDTO.getBuyerOpenid());

        List<WxMpTemplateData> data = Arrays.asList(
                new WxMpTemplateData("first", "亲，请记得收货。"),
                new WxMpTemplateData("keyword1", "微信点餐"),
                new WxMpTemplateData("keyword2", "18868812345"),
                new WxMpTemplateData("keyword3", orderDTO.getOrderId()),
                new WxMpTemplateData("keyword4", orderDTO.getOrderStatusEnum().getMessage()),
                new WxMpTemplateData("keyword5", "￥" + orderDTO.getOrderAmount()),
                new WxMpTemplateData("remark", "欢迎再次光临！")
        );
        templateMessage.setData(data);
        try {
            wxMpService.getTemplateMsgService().sendTemplateMsg(templateMessage);
        }catch (WxErrorException e) {
            log.error("【微信模版消息】发送失败, {}", e);
        }
    }
}

　　订单完结是发送

@Service
@Slf4j
public class OrderServiceImpl implements OrderService {

    @Autowired
    private ProductService productService;

    @Autowired
    private OrderDetailRepository orderDetailRepository;

    @Autowired
    private OrderMasterRepository orderMasterRepository;

    @Autowired
    private PayService payService;

    @Autowired
    private PushMessageService pushMessageService;
@Override
    @Transactional
    public OrderDTO finish(OrderDTO orderDTO) {
        //判断订单状态
        if (!orderDTO.getOrderStatus().equals(OrderStatusEnum.NEW.getCode())) {
            log.error("【完结订单】订单状态不正确, orderId={}, orderStatus={}", orderDTO.getOrderId(), orderDTO.getOrderStatus());
            throw new SellException(ResultEnum.ORDER_STATUS_ERROR);
        }

        //修改订单状态
        orderDTO.setOrderStatus(OrderStatusEnum.FINISHED.getCode());
        OrderMaster orderMaster = new OrderMaster();
        BeanUtils.copyProperties(orderDTO, orderMaster);
        OrderMaster updateResult = orderMasterRepository.save(orderMaster);
        if (updateResult == null) {
            log.error("【完结订单】更新失败, orderMaster={}", orderMaster);
            throw new SellException(ResultEnum.ORDER_UPDATE_FAIL);
        }

        //推送微信模版消息
        pushMessageService.orderStatus(orderDTO);

        return orderDTO;
    }
}
