JSP EL表达式忽略方法

JSP EL表达式忽略方法：

web.xml中，和jsp中；jsp中的等级要高一些；

web.xml:

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID"

    version="3.0">

    <display-name>TestBootWeb</display-name>

    <jsp-config>

        <jsp-property-group>

            <url-pattern>*.jsp</url-pattern>

            <el-ignored>false</el-ignored>

        </jsp-property-group>

    </jsp-config>

    <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

</web-app>

jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ page isELIgnored="true"%>

<%

    String path = request.getContextPath();

    String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";

    pageContext.setAttribute("pca", "pageContextAttribute");

%>

<!DOCTYPE html>

<html>

<head>

<meta charset="UTF-8">

<title>008index</title>

</head>

<body>

    EL result is :

    <p>${pageScope.pca }</p>

</body>

</html>
