重啟tomcat的時候出錯
Illegal access: this web application instance has been stopped already. Could not load oracle.net.mesg.Message. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

原因是因為在tomcat重啟的時候，之前的tomcat的線程還沒有完全關閉，最新啟動tomcat就會報這個異常，只要把tomcat的server.xml 中的reloadable="true" 改成false就OK
大家看過這個帖子后說沒有找到對應的配置，其實就存在於Context節點中，一下是我截取的Tomcat中文一個文檔中的注釋：| Context(表示一個web應用程序，通常為WAR文件，關於WAR的具體信息見servlet規范) | docBase | 應用程序的路徑或者是WAR文件存放的路徑 |
| path | 表示此web應用程序的url的前綴，這樣請求的url為http://localhost:8080/path/**** | |
| reloadable | 這個屬性非常重要，如果為true，則tomcat會自動檢測應用程序的/WEB-INF/lib 和/WEB-INF/classes目錄的變化，自動裝載新的應用程序，我們可以在不重起tomcat的情況下改變應用程序 |
