Java 无法从IntelliJ Tomcat中找到控制器

我在intelliJ中配置SpringMVC项目时遇到问题（我无法在此项目中使用SpringBoot）

我似乎无法击中我的控制器：

package app.controller;

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

import javax.servlet.http.HttpServletRequest;

@Controller
@RequestMapping(value = "/user")
public class UserController {

    @RequestMapping(value = "/registerUser", method = RequestMethod.GET)
    public String registerUser(Model m, HttpServletRequest request) {
        System.out.println("HERE");
        return "index";
    }
}

当我尝试localhost:8080/user/registerUser时，总是会出现404错误

我意识到为了拥有HttpServletRequest类，我需要导入pom.xml中的最后一个依赖项：

请重命名web->webapp并移入src->main文件夹
更新pom.xml，如下所示

   @Bean
         public ViewResolver viewResolver() {
             InternalResourceViewResolver resolver = new      InternalResourceViewResolver();
             resolver.setViewClass(JstlView.class);
            resolver.setPrefix("/");
            resolver.setSuffix(".jsp");
            return resolver;
     }

下面是一个工作示例


非常感谢，这就解决了问题！因为您已经下载了project，并且已经很熟悉它，您是否知道它为什么突然停止后台视频并显示错误：在名为“dispatcher”的DispatcherServlet中找不到URI为[/resources/video/background video.mp4]的HTTP请求的映射
