java – 嵌入式Jetty – Spring MVC – 视图解析器 – 无XML – HTTP错误：404

我正在尝试使用嵌入式Jetty建立一个简单的 Spring MVC服务器.我已经设置了服务器,启用了spring并为.jsp文件配置了一个视图解析器.控制器给我404以下消息：

Problem accessing /jsp/test.jsp. Reason:
Not Found

有谁知道问题是什么？我一直在谷歌上搜索两天.

服务器：

private static final int DEFAULT_PORT = 8080;
private static final String CONTEXT_PATH = "/";
private static final String CONFIG_LOCATION = "spring.config";
private static final String MAPPING_URL = "/*";

private EmbeddedJettyServer(){
}

public static void main(String[] args) throws Exception {
    Server server = new Server(DEFAULT_PORT);
    server.setHandler(getServletContextHandler(getContext()));
    server.start();
    server.join();
}

private static ServletContextHandler getServletContextHandler(WebApplicationContext context) throws IOException {
    ServletContextHandler contextHandler = new ServletContextHandler();
    contextHandler.setErrorHandler(null);
    contextHandler.setContextPath(CONTEXT_PATH);
    contextHandler.addServlet(new ServletHolder(new DispatcherServlet(context)),MAPPING_URL);
    contextHandler.addEventListener(new ContextLoaderListener(context));
    contextHandler.setResourceBase(new ClassPathResource("webapp").getURI().toString());
    return contextHandler;
}

private static WebApplicationContext getContext() {
    AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
    context.setConfigLocation(CONFIG_LOCATION);
    return context;
}

Spring配置/查看解析器：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages="controller")
public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    super.addResourceHandlers(registry);
    registry.addResourceHandler("/html/**").addResourceLocations("/resources/html/");
}

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix("/jsp/");
    viewResolver.setContentType("text/html; charset=UTF-8");
    viewResolver.setSuffix(".jsp");
    return viewResolver;
}

控制器：

@RequestMapping("/")
public ModelAndView index() {
    return new ModelAndView("test");
}

编辑：
文件夹结构：

│   │   │   ├───controller

│   │               test.jsp
│   │
│   └───test
│       └───java
└───target

pom.xml中：

<resources>
        <resource>
            <targetPath>/webapp</targetPath>
            <directory>src/main/webapp</directory>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
        </resource>
    </resources>

解决方法

"MAPPING_URL" to "/".
"ServletContextHandler" to "WebAppContext"

在pom中添加了missin依赖：

<dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-jsp</artifactId>
        <version>9.2.0.M0</version>
    </dependency>

还必须配置IDE以使用JDK而不是JRE
