Spring o.s.web.servlet.PageNotFound未找到具有URI的HTTP请求的映射

Question

我正在尝试制作我的第一个spring mvc应用程序，当我尝试查看我的页面时遇到问题。它是根据教程创建的，但是在我的计算机上不起作用。我还没有创建任何xml文件，也没有更改Gradle中的配置。 我正在使用macOS 11

项目结构：

DispatcherServelet：

package com.vavalang.Magazine;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class DispatcherServlet extends AbstractAnnotationConfigDispatcherServletInitializer{

@Override
protected Class<?>[] getRootConfigClasses() {

    return null;
}

@Override
protected Class<?>[] getServletConfigClasses() {

    return new Class[] {WebConfig.class};
}

@Override
protected String[] getServletMappings() {

    return new String[] {"/"};
}

}

MagazineController：

package com.vavalang.Magazine;

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


@Controller
public class MagazineController {

    @RequestMapping(value = "/")
    public String home(Model model) {

        model.addAttribute("nick", "Jan");
        return "home";
    }
}

WebConfig：

package com.vavalang.Magazine;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
@EnableWebMvc
@ComponentScan("com.vavalang.Magazine")
public class WebConfig implements WebMvcConfigurer{

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {

        registry.jsp();
    }
}

MagazineApplication：

package com.vavalang.Magazine;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;


@SpringBootApplication
public class MagazineApplication {

    public static void main(String[] args) {
        SpringApplication.run(MagazineApplication.class, args);
    }
}

然后登录：
