Question

return new ModelAndView("/WEB-INF/jsp/welcome.jsp","dateAndTime",dateAndTime);

package com.vpp.fleetman.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.Date;

@Controller
public class FirstController {

  @RequestMapping("/home.html")
    public ModelAndView firstPage(){
      Date dateAndTime = new Date();
     
     //This work, I just want to remove the hard coded and use application.properties
     // return new ModelAndView("/WEB-INF/jsp/welcome.jsp","dateAndTime",dateAndTime);
    
    //Let's use a view resolver for the views
    return new ModelAndView("welcome","dateAndTime",dateAndTime);
  }
}

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<h1>Welcome from Intelij ..... Time is: ${dateAndTime} </h1>

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
/welcome.jsp

当我使用application.properties的引用时，它就不起作用了...当我保留硬编码裁判时？？如能提供任何指导，不胜感激。

Answer 1

谢谢你的建议。答案是卢克·伍德沃德的提议...在文件application.properties中。错字错误。

prefix：/WEB-INF/jsp/vs spring.mvc.view.prefix：/WEB-INF/jsp/

我还尝试了:and=，两者都有效。
