Question

尝试了数周之后，才尝试启动并运行Spring MVC App并使用Jetty服务器。问题是，即使它可以找到WebApplicationInitializers并且日志没有抛出任何可疑的信息，它也会给我一个Error 404 Not Found。好像它不能或不会听我定义的控制器。这是一个没有XML的纯Java配置Spring MVC webapp

我正在使用这些指南：

http://www.mkyong.com/spring3/spring-3-mvc-hello-world-example-annotation/

和

https://www.mkyong.com/spring-mvc/gradle-spring-4-mvc-hello-world-example-annotation/

我的POM像这样配置jetty-maven-plugin：

<plugin>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>${jetty.version}</version>
    <configuration>
        <scanIntervalSeconds>10</scanIntervalSeconds>
        <webApp>
            <contextPath>/</contextPath>
        </webApp>
    </configuration>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <downloadSources>true</downloadSources>
        <downloadJavadocs>true</downloadJavadocs>
        <wtpversion>2.0</wtpversion>
        <wtpContextName></wtpContextName>
        </configuration>
</plugin>

以下是我的目录结构：

扫描文件只是告诉Spring扫描co.uk.naz.cv中的所有内容，以便在子程序包中获取批注。

所有其他都是典型配置：

我的WebConfig类：

@Configuration
@EnableWebMvc
public class WebConfig
{
    @Bean
    public ViewResolver viewResolver()
    {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(JstlView.class);
        resolver.setPrefix("/WEB-INF/views/jsp/");
        resolver.setSuffix(".jsp");
        resolver.setExposeContextBeansAsAttributes(true);
        return resolver;
    }

    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        registry.addResourceHandler("/js/**", "/css/**", "/images/**")
        .addResourceLocations("/resources/core/js/", "/resources/core/css/", "/resources/core/css/images")
        .setCachePeriod(3600)
        .resourceChain(true)
        .addResolver(new PathResourceResolver());
    }
}

我的RootConfig：

@Configuration
@ComponentScan(excludeFilters = { @Filter(type=FilterType.ANNOTATION, value=EnableWebMvc.class) })
public class RootConfig
{
    //Class is intentionally left empty
}

WebAppInitialiser：

public class WebAppInitialiser extends AbstractAnnotationConfigDispatcherServletInitializer
{
    @Override
    protected String[] getServletMappings() { return new String[] { "/" }; }

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

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

和简单的控制器：

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

这一直是一场噩梦，而离我最近的是它正在获得目录列表，该目录列表使我可以导航到html文件。

希望这是一个简单的解决方法，但是我一生无法看到这里出了什么问题。我想要的只是让此WebApp返回index.jsp文件。我已经仔细检查了所有路径，并确定它们是正确的。

为完成此操作，请参阅日志：

Maven Spring Jetty服务器找不到任何东西
