我从这门类(class)开始学习“Spring MVC”:http://www.pluralsight.com/training/Courses/TableOfContents/springmvc-intro在“构建->运行应用程序”步骤中，我陷入了困境。

当我尝试访问链接http://localhost:8080/FitnessTracker/greeting.html我收到“HTTP 状态 404”

HTTP Status 404 - /FitnessTracker/WEB-INF/jsp/Hello.jsp
type Status report
message /FitnessTracker/WEB-INF/jsp/Hello.jsp

HelloController.java

package com.pluralsight.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {

    @RequestMapping(value = "/greeting")
    public String sayHello (Model model) {
        model.addAttribute("greeting", "Hello WorldX");
        return "Hello"; 
    }
}

hello.jsp

http://localhost:8080/FitnessTracker/ - 工作正常(文件:webapp/index.jsp)

最佳答案

错误消息表明它正在寻找 Hello.jsp。事实上，您的 Controller 返回以下 View 名称:“Hello”。但您的屏幕截图显示您的文件名为 hello.jsp。案件很重要。
