<mvc: resources> come utilizzare la posizione del percorso di classe

Question

Ho cercato in alto e in basso per risolvere questo problema, ma non riesco a trovare una soluzione. Il problema è il seguente: Ho un build di webapp Spring-mvc su un server Tomcat 7 - 7.0.12 per essere precisi - e ho problemi a far funzionare correttamente il tag <mvc:resources>. Come vedrai sotto, il <mvc:resources> funziona per la vecchia cartella delle risorse, ma preferisco avere la cartella delle risorse nella directory /WEB-INF/web/.

MediorkoorVOICES-Web-servlet.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd 
     http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">   

    <context:component-scan base-package="com.oudejans.mediorkoorvoices.web" /> 

    <mvc:resources mapping="/resources/**" location="/WEB-INF/web/resources/" /> 
    <mvc:annotation-driven /> 

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 
     <property name="prefix" value="/WEB-INF/web/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
     <property name="order" value="1" /> 
    </bean> 

    <bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> 

    <import resource="web/tiles/web-tiles.xml" /> 
</beans> 

struttura di cartelle:

META-INF 
resources (Old resources folder) 
    - web 
     - images 
     - css 
      - main.css  
WEB-INF 
    - classes 
    - lib 
    - admin 
    - shared 
    - web 
     - jsp 
     - tiles 
     - resources (New resources folder i want to access) 
      - images 
       - banner.png 
      - js 
      - etc. 

Ora se volevo accedere alla cartella delle risorse vecchio, il codice qui sotto avrebbe funzionato.

<mvc:resources mapping="/resources/**" location="/resources/" /> 
& 
<img src="${pageContext.request.contextPath}/resources/oldBanner.png" /> 

Ma quello che preferirei è quello di fare qualcosa di simile:

<mvc:resources mapping="/resources/**" location="classpath:/WEB-INF/web/resources/" /> 
& 
<img src="${pageContext.request.contextPath}/resources/images/banner.png" /> 

qualcuno può spiegarmi come faccio questo? Sono abbastanza nuovo per la primavera-mvc.

EDIT1: dati aggiuntivi: sto usando netbeans 7.1.2 e la versione spring-mvc è 3.1.0 in combinazione con maven.

Edit3 : Dopo alcuni test, mi sono reso conto che il tag <mvc:resources> non funziona affatto. (Guarda struttura delle cartelle aggiornato) Se io, per esempio, fare:

<mvc:annotation-driven /> 
<mvc:resources location="/resources/web/" mapping="/resources/**" /> 
& 
<a href="${pageContext.request.contextPath}/resources/css/main.css" />click</a> 

Mi dà una 404 così, mentre in realtà, dovrebbe collegare al file /resources/web/css/main.css . Quindi tutto ciò a cui riesco a pensare adesso è che c'è qualche configurazione mancante.

Answer 1

Così, dopo un sacco di debug e "provare" le cose, mi ho provato ad aggiungere la mappatura * .css e * .png al web.servlet xml. Apparentemente, i file delle risorse non sono stati mappati al servlet e quindi non è stato possibile trovare. Pertanto, per tutti coloro che hanno la stessa mappatura della mia, aggiungi questo al tuo tag web.xml servlet-mapping.

<url-pattern>*.css</url-pattern> 
<url-pattern>*.png</url-pattern> 

Answer 2

Quello che stai facendo è totalmente sbagliato. Poiché le risorse sono nella cartella /WEB-INF/web/resources/, non è necessario specificare il percorso classe : prima di esso.

quindi sarebbe proprio come sotto

<mvc:resources mapping="/WEB-INF/web/resources/**" location="/WEB-INF/web/resources/" /> 

Penso che sarebbe risolvere il problema. Spero che questo ti aiuti. Saluti.

Answer 3

Questo dovrebbe funzionare:

<mvc:resources location="WEB-INF/resources/" mapping="/resources/**" /> 

Lei si riferisce alle risorse utilizzando un URI di /resources/somestatic.gif ma sarà servito da WEB-INF/resources/somestatic.gif
