1.JSTL简介
3.有关逻辑的简单示范（通常和EL表达式一起使用）
1.if标签（属性：test--如果为true则返回标签体内容,相当于java中的if语句）
2.choose标签（相当于Java中的switch语句）
3.foreach标签使用（相当于Java中的for循环）
其中，items表示当前你要遍历的对象，比如数组。var表示其中的一个元素，varStatus : 当前状态，可以获取序号.
4.综合使用案例
<%@ page import="com.lyg.servlet.simple_class.Student" %>
<%@ page import="java.util.Date" %>
<%@ page import="java.util.List" %>
<%@ page import="java.util.ArrayList" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %><!--导入格式化标签库 -->
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
