Servlet.init() for servlet SpringMVC threw exception错误

检查了一遍发现web出现错误如下：

No provider available for the service com.dream.service.ItemService from the url zookeeper://127.0.0.1:2181/com.alibaba.dubbo.registry.RegistryService?application=dream_manager_web&dubbo=2.5.3&interface=com.dream.service.ItemService&methods=list,selectBykey&pid=648&revision=1.0-SNAPSHOT&side=consumer&timestamp=1584950033676 to the consumer 169.254.38.131 use dubbo version 2.5.3
最终排查出来的是manager中的分页插件pagehelper出错

这样是有问题的，更改后为

这样终于没有再出错了
