My Dao Class看起来像

package com.mvn.blog.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.mvn.blog.domain.UserDomain;
import com.mvn.blog.dto.UserDto;
import com.mvn.blog.service.IUserMaintenance;
import com.mvn.blog.utility.CommonUtils;

@Controller
public class HomeController {


    @Autowired
    IUserMaintenance userMaintenance;


    @RequestMapping("/home")
    public String home(){
        return "index";
    }

    @RequestMapping(value = "/userlist" , method = RequestMethod.GET)
    public ModelAndView  getUserList() throws Exception{
        List<UserDto> userList = userMaintenance.getUserList();
        //System.out.println(userList);

        for(UserDto users : userList){
            System.out.println(users.getUsername()+" "+ users.getEmail()+" "+users.getPassword());

        }

        return new  ModelAndView("viewuser", "userList" , userList);
}

}





My Jsp File

    pageEncoding="ISO-8859-1"%>

我的controllerClass

这是bcoz您正在使用由DTD定义的旧JSP 1.2描述符默认情况下禁用或忽略EL，您必须手动启用它使用标准的JSP 2.0或更高版本的描述符，由w3c schema定义。

<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">
/...
</web-app>
