  • 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>
