解決failed to unregister JDBC driver導致可能記憶體洩露的問題
將mysql的驅動包mysql-connector-java-5.1.39從webContent->web-inf->lib移到tomcat的lib目錄下,既可以簡化新建web專案時的導包麻煩,也能解決專案關閉時記憶體洩露的問題 The web application [] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped。查閱的這個網站https://stackoverflow.com/questions/24850091/the-web-application-registered-the-jdbc-driver-com-mysql-jdbc-driver-but-fa。
目前為之還不知道為什麼。
