【DRP】-JSTL核心库 c:out标签

1、引入jar包

 

index页面：作用点击连接调用页面

<a href="servlet/JstlCoreServlet">测试JSTL核心库</a><br>

 

JstlCoreServlet类，作用：存储数据，转发页面！
package com.bjpowernode.jstl;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class JstlCoreServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        //普通字符串
        request.setAttribute("hello", "Hello World");
        
        request.getRequestDispatcher("/jstl_core.jsp").forward(request, response);
    }

}

 

jstl_core.jap页面

<%@ page language="java" contentType="text/html; charset=GB18030"
    pageEncoding="GB18030"%>
 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB18030">
<title>Insert title here</title>
</head>
<body>
    <hl>测试JSTL核心库</hl>
    <hr>
    <li>采用c:out标签</li><br>
    hell(使用标签)：<c:out value="123"/>
   
</body>
</html>

 

引入jar包路径：

 

 

其中的jar包在文件中查找！
