從網上尋找解決辦法
最后本人在apache基金會官網論壇看到國外大牛討論“Take a look at how to disable annotation scanning for the Jetty jars or disabling WebSocket support altogether in Tomcat if you don‘t need it so that Tomcat won‘t try and start those classes.”安得則answer是“Thanks, that is really the cause. Adding <absolute-ordering/> to web.xml fixed the problem. From doc:”。此時在我的web.xml找到這個服務添加上這個元素絕對順序屬性，WTF！紅線一片片。最后無奈之下destroy掉了這個web.xml，idea用得到它會自己生成的不是，結果問題就好了。
就好了.....
是說把web.xml刪掉就好了嗎？
