Java Spring@RequestMapping，404错误

所以，我试图学习Spring框架，但目前我被困在这个问题上，由于某些原因，我的映射无法工作，当我尝试访问那个地址时，我得到了一个404错误

有人能澄清我做错了什么吗（无论是在spring类的使用方面还是在我上面描述的问题的根源方面）

我正在使用本视频中所示的示例配置spring，代码基本相同，唯一的区别是包名和JSP文件的位置（这可能是我的问题的根源吗？）

作为我的servlet容器，我使用Tomcat8（尝试了9和8.5，没有雪茄）

HomeController.java

package com.demo.spring.controller;

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

package com.demo.spring.controller;

import org.springframework.stereotype.Controller;

/**

@Controller
public class HomeController {
    @RequestMapping("/")
    public String home() {
        return "home";
    }
}

package com.demo.spring.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

@Configuration
public class WebInit extends AbstractAnnotationConfigDispatcherServletInitializer {

    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{RootConfig.class};
    }

    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[]{WebConfig.class};
    }

    protected String[] getServletMappings() {
        return new String[]{"/"};

        resolver.setSuffix(".jsp");

home.jsppath:/web/home.jsp

好的，所以我找到了解决方案

将war插件添加到pom.xml

修复web资源目录路径（was webapp）

你应该把密码放在这里。哎呀，对不起，忘了。DoneSo，我忘了在pom.xml中添加war，但它仍然没有解决我的问题，它确实映射URL，但我仍然得到404错误。它显示HTTP状态404-/home.jsp，因此出于某种原因，它无法找到my view aka home.jspHow来添加war插件：
