package com.lmz.controller;import java.text.SimpleDateFormat;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;@Controller@RequestMapping("welcome")public class HelloWordController {@RequestMapping(value="printWelcome")    public String printWelcome(ModelMap model) {        model.addAttribute("message", "Spring3 MVC");        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");        model.addAttribute("date", dateFormat.format(new java.util.Date()));        return "hello";    } }

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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=UTF-8"><title>Insert title here</title></head><body><h1>Message:${message}</h1><h2>当前时间：${date}</h2></body></html>

显示结果为：

Message:${message}当前时间：${date}

导致的原因是jsp中 EL默认为true，默认是忽略的，加上下面红色字体就可以正常显示了：

<%@ page isELIgnored="false" language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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=UTF-8"><title>Insert title here</title></head><body><h1>Message:${message}</h1><h2>当前时间：${date}</h2></body></html>
