嵌入式Jetty和Spring MVC未映射index.jsp

Question

我对Spring MVC比较陌生，并且具有Embedded Jetty的工作知识。我们有一个现有的Spring MVC Web应用程序，我可以编译成一个战争并投入到Tomcat中，并且它工作正常。不过，我现在想要在Embedded Jetty中运行它，而不必将其放到Tomcat中。

我按照这个教程中，我发现有帮助的（有一些小的改动）：

http://kielczewski.eu/2013/11/using-embedded-jetty-spring-mvc/

，一切似乎是“几乎” OK，但似乎对我的JSP的映射不上班。

这里是我的主类：

public class EmbeddedJetty { 

    private static final int DEFAULT_PORT = 8080; 
    private static final String CONTEXT_PATH = "/"; 
    private static final String CONFIG_LOCATION = "/WEB-INF/spring-servlet.xml"; 
    private static final String MAPPING_URL = "/*"; 

    public static void main(String[] args) throws Exception { 
     new EmbeddedJetty().startJetty(getPortFromArgs(args)); 
    } 

    private static int getPortFromArgs(String[] args) { 
     if (args.length > 0) { 
      try { 
       return Integer.valueOf(args[0]); 
      } catch (NumberFormatException ignore) { 
      } 
     } 
     return DEFAULT_PORT; 
    } 

    private void startJetty(int port) throws Exception { 
     Server server = new Server(port); 
     WebApplicationContext context = getContext(); 
     ServletContextHandler servletContextHandler = getServletContextHandler(context); 
     server.setHandler(servletContextHandler); 

     server.start(); 
     server.join(); 

     ResourceHandlerRegistry rhr = new ResourceHandlerRegistry(context, servletContextHandler.getServletContext()); 
     rhr.addResourceHandler("images/**").addResourceLocations("images/"); 
     rhr.addResourceHandler("jsp/**").addResourceLocations("jsp/"); 
     rhr.addResourceHandler("css/**").addResourceLocations("css/"); 
    } 

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

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

这是我的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    id="WebApp_ID" version="2.5"> 

    <!-- Welcome file --> 
    <display-name>USER Administration</display-name> 
    <welcome-file-list> 
     <welcome-file>index.jsp</welcome-file> 
    </welcome-file-list> 

    <!-- This is the servlet that will route to the correct Controller based on annotations --> 
    <servlet> 
     <servlet-name>spring</servlet-name> 
     <servlet-class> 
      org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <!--Map non-resource URLs to the DispatcherServlet --> 
    <servlet-mapping> 
     <servlet-name>spring</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

    <!-- Allow access to the resources --> 
    <servlet-mapping> 
     <servlet-name>default</servlet-name> 
     <url-pattern>*.png</url-pattern> 
     <url-pattern>*.js</url-pattern> 
     <url-pattern>*.css</url-pattern> 
    </servlet-mapping> 

</web-app> 

这是我为spring-servlet.xml（相关部分 - 我认为）：

<!-- This is the base package(s) for where spring should scan for @Component, @Service, @Controller, etc --> 
    <context:component-scan base-package="com.my.user.admin" /> 

    <!-- A resolver for the returned ModelAndView objects and other strings, this tells it to append .jsp and look in the /WEB-INF/jsp/ for it --> 
    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
     <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 
     <property name="prefix" value="/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 
     <!-- one of the properties available; the maximum file size in bytes --> 
     <property name="maxUploadSize" value="100000"/> 
    </bean> 

    <!-- loads in property files for use in this config --> 
    <bean id="propertyConfigurer" 
     class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
     <property name="locations"> 
      <list> 
       <value>classpath:Frameworks/hibernate.properties</value> 
       <value>classpath:Frameworks/activemq.properties</value> 
      </list> 
     </property> 
    </bean> 

    <!-- Hibernate 3 session factory used for session management --> 
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
     <property name="configLocation" value="classpath:${hibernate.config.location}" /> 
    </bean> 

然后我用maven遮罩插件构建它，并使用以下命令运行它：

java -classpath c:\dev\customclasspath;target\user-admin.jar com.admin.main.EmbeddedJetty 

它启动时，所有在日志中看起来不错，我看到很多线在那里装载我的Java类到网址：

Mapped URL path [/modifyUser] onto handler 'menuController 
Mapped URL path [/modifyUser.*] onto handler 'menuControll 
Mapped URL path [/modifyUser/] onto handler 'menuControlle 
Mapped URL path [/addUser] onto handler 'menuController' 
Mapped URL path [/addUser.*] onto handler 'menuController' 
Mapped URL path [/addUser/] onto handler 'menuController' 

但是当我尝试加载了我的应用程序在“本地主机：8080”，我得到一个“未找到 - 技术码头”页面，在我看到以下消息日志：

No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'org.springframework.web.servlet.DispatcherServlet-6910fe28' 

我在做什么错？在我的jar文件中，我可以看到文件/webapp/index.jsp，所以我认为它可能是这样，但是如果我执行“localhost：8080/webapp /”，那也不起作用。我不知道现在要改变什么，任何帮助将不胜感激！

EDIT1

我相信这个问题是因为它不是实际加载我的web.xml文件（这里我定义了servlet的映射），因为我创造了码头上下文作为Spring上下文，而不是'WebAppContext'。不过，我需要spring-servlet.xml文件，因为它包含我所有的控制器。我如何加载？

Answer 1

欢迎文件仅在没有URI的servlet映射时使用。你的情况有一个：

<servlet-mapping> 
    <servlet-name>spring</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

这种处理什么除了巴纽/ .js文件/的CSS。
