1、常量

public interface WechatConsts {
// String WECHAT_APP_ID="wx0afb876c6fc70e1e";
// String WECHAT_APP_SECRET="1e7db4c466a2846006836c0007991d49";
// String TEMPLATE_ID="cLrzp2ThnYNhKUySQADT8Yqizyd9Cdm7qUzKgOFSoBs";

 String WECHAT_APP_ID="wx9648a4f1ddb1abfa";
 String WECHAT_APP_SECRET="5db2c92690351b04f01a06913abdf186";
 String TEMPLATE_ID="cLrzp2ThnYNhKUySQADT8Yqizyd9Cdm7qUzKgOFSoBs";
}

2、controller代码

@RestController
@RequestMapping("/api/WechatTemplateMsg")
public class WechatTemplateMsgController {
    @Autowired
    WechatTemplateMsgService wechatTemplateMsgService;
    @Autowired
    private GoodsInfoService goodsInfoService;
    @Autowired
    private OrderSubFormDao subFormDao;
    @Autowired
    private WechatUserInfoService userInfoService;
    //获取活动提醒
    @RequestMapping("getActivity")
    public R getactivityMsg(String openid, String activity_name, String activity_address, String activity_time)
    {
        wechatTemplateMsgService.common(openid,activity_name,activity_address,activity_time,"您报名的活动即将开始");
        return R.ok();
    }


    //获取签到确认通知
    @RequestMapping("getCheckInMsg")
    public R getTemplateMsg(String orderId)
    {
        String openid="";
        String activity_name="";
        String activity_address="";
        String activity_time="";
        OrderSubFormEntity subFormEntity = subFormDao.selectById(orderId);
        if (subFormEntity!=null){
            GoodsInfoEntity goodsInfo =goodsInfoService.getById(subFormEntity.getGoodsId());
            if (goodsInfo!=null) {
                openid=userInfoService.getOpenIdByOrderId(subFormEntity.getOrderId());
                activity_name = goodsInfo.getName();
                activity_address = goodsInfo.getAddress();
                activity_time = DateUtil.formatDateTime(goodsInfo.getStartTime());
            }
        }
        wechatTemplateMsgService.getCheckInMsg(openid,activity_name,activity_address,activity_time,"您已成功签到");
        return R.ok();
    }

}

3、service代码

@Service
public class WechatTemplateMsgService {
    public void common(String openid, String activity_name, String activity_address, String activity_time,String texttitle)
    {
        String accessToken = TokenUtil.getAccessToken();
