<?xml version="1.0" encoding="UTF-8"?> <!-- 資料庫連接池設定檔 --> <Context>    <Resource         name="jdbc/ConnectionPool"        auth="Application"        type="javax.sql.DataSource"         username="root"         password="root"        driverClassName="com.mysql.jdbc.Driver"         url="jdbc:mysql://localhost:3306/pwapplication?relaxAutoCommit=true&amp;zeroDateTimeBehavior=convertToNull"        maxActive="8"         maxIdle="4"        /> </Context>

然後在JSP頁面添加代碼，擷取時間後，需要將時間格式化成為自己需要的格式。
