Several ports required by Tomcat already in use

有時eclipse運行時出現異常，須要使用 任務管理器 強行中止時，再啓動eclipse，啓動Tomcat時報錯以下：

Several ports (8080, 8080) required by Tomcat v6.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

解決方案是：打開Tomcat的安裝目錄，找到bin文件夾（如路徑  C:\apache-tomcat-7.0.64\bin）下的shutdown.bat，運行該文件。重啓Tomcat即正常。
