<?xml version="1.0" encoding="UTF-8"?>
 <!-- 数据库连接池配置文件 -->
 <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>

然后在JSP页面添加代码，获取时间后，需要将时间格式化成为自己需要的格式。

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page  import="java.sql.*" %>
<%@ page import="javax.naming.*" %>
<%@ page import="javax.sql.DataSource,java.text.Format,java.text.DateFormat" %>
<%@ page import="java.text.SimpleDateFormat" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

    Context initCtx = new InitialContext(); 
    Context ctx = (Context) initCtx.lookup("java:comp/env"); 
    //获取连接池对象 
    DataSource ds =(DataSource)ctx.lookup("jdbc/ConnectionPool"); 
    //创建连接
    Connection conn = ds.getConnection(); 
    System.out.println("conn="+conn);
    Statement stmt = conn.createStatement();
    String mysql="select * from notification_tb";
    ResultSet myrs=stmt.executeQuery(mysql); //执行查询

       <%
               String notiID=myrs.getString("notiID");

              //格式化时间
               String fmtTime=spf.format(notiTime);
        %> 
            <%    
                System.out.println(notiTheme);
                System.out.println(notiContent);
                System.out.println(notiTime);
                System.out.println(fmtTime);
              %>
                  <dt>>><a href="notidetail?notiID=<%=notiID %>"><%=notiTheme %></a></dt>
