前提：JDK，Eclipse，Tomcat裝好，環境變量配好
- 添加Eclipse的Tomcat插件（下載路徑：http://www.eclipsetotale.com/tomcatPlugin.html）
- 插件裝好之後Window -〉 Perferences -〉 Tomcat 配置Tomcat路徑，然後重啟eclipse
- 新建一個Tomcat Project：ServletDemo
- 右鍵ServletDemo工程 -〉 創建一個Class：ServletDemo.java（創建的Class會自動生成到/WEB-INF/src目錄中）
- 在WEB-INF下添加web.xml
- 點開Project看看Build Automatically又沒有鉤上，沒有鉤上說明不是自動編譯，需要手動Alt + B編譯一下
- 啟動Tomcat，IE輸入http://localhost:8888/ServletDemo/show運行
