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>
