Es ist keine Aktion für den Namespace/und den Aktionsnamen userfiles/images/in Struts2 zugeordnet.

Question

Ich habe Probleme, einige Bilder in Struts2 anzuzeigen. Wenn eine Seite, die Bilder aus der Datenbank hat geladen, ex:

<img src="userfiles/images/${imageName}" width="200px"/>

oder

<img src="userfiles/images/<s:property value="imageName"/>" width="200px"/>

Ich halte diesen seltsamen Fehler bekommen, mir zu sagen, dass es keine solche Wirkung wie das ist Pfad Benutzerdateien/Bilder/. Was ist das Problem?

Filterkonfiguration:

<filter> 
    <filter-name>struts2</filter-name> 
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 
</filter> 
<filter-mapping> 
    <filter-name>struts2</filter-name> 
    <url-pattern>/*</url-pattern> 
    <dispatcher>FORWARD</dispatcher> 
    <dispatcher>REQUEST</dispatcher> 
</filter-mapping> 

Ausnahme:

There is no Action mapped for namespace/and action name userfiles/images/. - [unknown location]
