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：

解决方法
解：
在“EmbeddedJettyServer”中我改变了
在“EmbeddedJettyServer”中我改变了
"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
