Answer 1

看看你CommunicationsException里面的配置信息，如果没错就是数据库没启动。。。

Answer 2

项目能跑不 能的话可以不用管这个异常 这是tomcat的问题。
当tomcat重启时 tomcat的线程还没有完全关闭，重启时就会发生这种异常，如果你非要改的话，方法如下：
修改tomcat下的server.xml文件 将reloadable改为false，如下
<Context path="/expert" docBase="expert" debug="0" reloadable="false">
但是这样做有个弊端是tomcat的热部署就会出问题，不利于开发！希望能帮到你！
