我从本课程开始学习“Spring MVC”：在步骤“构建->运行应用程序”中，我被卡住了

当我尝试转到链接

http://localhost:8080/FitnessTracker/greeting.html

我得到“HTTP状态404”

web.xml

hello.jsp

<%@ page language="java" contentType="text/html; charset=US-ASCII"
    pageEncoding="US-ASCII"%>

<body>
  <h1>${greeting}</h1>
</body>
</html>


在此处插入标题
${问候语}

http://localhost:8080/FitnessTracker/

-它的工作（文件：webapp/index.jsp）

尝试从控制器返回与jsp

hello.jsp

匹配的正确大小写视图名称。当前，控制器返回

Hello

，而JSP名为

Hello.JSP

，导致404

@Controller
public class HelloController {

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

错误消息说它正在查找

Hello.jsp

。实际上，您的控制器返回以下视图名称：

“Hello”

。但是您的屏幕截图显示您的文件已分析

hello.jsp

。案例很重要。

更改web.xml

<servlet-mapping>
   <servlet-name>fitTrackerServlet</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>


fitTrackerServlet
/

您是否尝试过注释版本的

InternalResourceViewResolver

？
