然而之前已经提出了这样的问题,或者给出的答案对我没有用,或者答案完全回避了问题而支持不同的基本示例。

我试图使用嵌入在Jetty实例中的Spring MVC servlet的简单基本示例。我的控制器正在拾取页面请求并返回正确的视图名称。当jsp页面被查找失败时。我相信,问题在于Servlet Mappings,基于我已经看过的其他答案,但我没有看到解决方案。

Jetty服务器设置:

public JettyServer(int port) throws JettyServerException {
    webServerPort = port;
    webServer = new Server(webServerPort);
    webServer.setStopAtShutdown(true);
    try {
        webServer.setHandler(getServletContextHandler(getContext()));
    } catch (IOException e) {
        throw new JettyServerException("Cannot instantiate JettyServer instance", e);
    }
}

private ServletContextHandler getServletContextHandler(WebApplicationContext context) throws IOException {

    ServletContextHandler contextHandler = new ServletContextHandler();
    contextHandler.setContextPath("/");

    contextHandler.addServlet(new ServletHolder(new DispatcherServlet(context)), "/");
    contextHandler.addEventListener(new ContextLoaderListener(context));
    contextHandler.setResourceBase(new ClassPathResource("webapp").getURI().toString());

    return contextHandler;
}

private WebApplicationContext getContext() {
    AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
    context.setConfigLocation("com.company.webapptemplate.config");
    return context;
}

在包com.company.webapptemplate.config下找到的Web App配置类:

@Configuration
@EnableWebMvc
@ComponentScan("com.company.webapptemplate.controller")
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    @Bean
    public UrlBasedViewResolver setupViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }
}

控制器代码:

@Controller
@RequestMapping("/")
public class ApplicationController {

    @RequestMapping(method = RequestMethod.GET)
    public String welcome(ModelMap model) {
        return "index";
    } 
}

运行maven / IntelliJ构建后target/classes下的非java类内容:

|____webapp
| |____WEB-INF
| | |____views
| | | |____index.jsp
| | |____web.xml (unused)

在IntelliJ中运行应用程序后将浏览器指向localhost:8080时的响应:

Problem accessing /WEB-INF/views/index.jsp. Reason:

    Not Found

原木中的吸烟枪我不知道该怎么办:

如果有人能告诉我我错过了哪一块拼图,我将非常感激。

感谢。

Sotirios评论推动了我前进 - 如何让Jsp处理servlet进入嵌入式Jetty ....

getServletContextHandler中,我将contextHandler的实例化更改为WebAppContext。所有相同的方法都适用于此。

然后我创建了这个方法来获取返回的WebAppContext并设置Jsp Handling(从这里获取的片段:https://github.com/jetty-project/embedded-jetty-jsp/blob/master/src/main/java/org/eclipse/jetty/demo/Main.java

private void setupJspHandler(WebAppContext context) {

    //Ensure the jsp engine is initialized correctly
    JettyJasperInitializer sci = new JettyJasperInitializer();

    ServletContainerInitializersStarter sciStarter = new ServletContainerInitializersStarter(context);
    ContainerInitializer initializer = new ContainerInitializer(sci, null);
    List<ContainerInitializer> initializers = new ArrayList<ContainerInitializer>();
    initializers.add(initializer);
    context.setAttribute("org.eclipse.jetty.containerInitializers", initializers);
    context.addBean(sciStarter, true);

    // Set Classloader of Context to be sane (needed for JSTL)
    // JSP requires a non-System classloader, this simply wraps the
    // embedded System classloader in a way that makes it suitable
    // for JSP to use
    ClassLoader jspClassLoader = new URLClassLoader(new URL[0], this.getClass().getClassLoader());
    context.setClassLoader(jspClassLoader);

    // Add JSP Servlet (must be named "jsp")
    ServletHolder holderJsp = new ServletHolder("jsp",JspServlet.class);
    holderJsp.setInitOrder(0);
    holderJsp.setInitParameter("logVerbosityLevel","INFO");
    holderJsp.setInitParameter("fork","false");
    holderJsp.setInitParameter("xpoweredBy","false");
    holderJsp.setInitParameter("compilerTargetVM","1.7");
    holderJsp.setInitParameter("compilerSourceVM","1.7");
    holderJsp.setInitParameter("keepgenerated","true");
    context.addServlet(holderJsp, "*.jsp");
}

我在我的maven pom中导入了以下内容:

<dependency>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-jsp</artifactId>
  <version>${jetty.version}</version>
</dependency>

<dependency>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>apache-jsp</artifactId>
  <version>${jetty.version}</version>
</dependency>

并且还必须将我的日志记录关闭,因为它检查WHOLE类路径时,servlet初始化程序的运行转储了WebApplicationInitializer扫描的日志记录,尽管其他问题和页面似乎提供了一些如何处理此问题的提示,例如....

https://jira.codehaus.org/browse/JETTY-1503
