指令(Directive)标记

taglib 指令
<%@ page language="java" %>
<%@ include file="test.html"%>
<%@ taglib uri="http://www.deng.com/tags" prefix="util" %>
<%@ page contentType = "text/html" %>
或者
<%@ page contentType = "text/html;charset=UTF-8" %>
<%@ page pageEncoding="UTF-8" %>
<%@ page import="java.io.*, java.util.Hashtable" %>
<%@ page session="true" %> //默认为true
<%@ page isErrorPage="true" %> //专门显示错误信息的页面
<%@ page errorPage="/error.jsp" %> //如果在当前的页面中出现违例了, 会跳转到error.jsp页面来处理错误信息
