controller代码
package com.hp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.validation.Errors;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/blog")
public class BlogController {
@RequestMapping("/{id}")
public ModelAndView blog(ModelAndView mv,@PathVariable("id") Integer id){
mv.addObject("msg", id);
mv.setViewName("blog");
return mv;
}
}
接受数据的jsp页面
<%@ 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>
${msg}
</body>
</html>
运行结果如图 EL表达式不起作用
解决办法
一种是在 jsp页面加上这句话
<%@page isELIgnored="false" %>
然后正常显示了.如图
