使用Spring 3提供静态内容

Question

I'm trying to use resources mapping feature of Spring 3 and it does not seem to be working. Here is what I have:

<servlet>
    <servlet-name>aaa</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

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

in my web.xml

then in my aaa-servlet.xml I have the following:

<resources mapping="/resources/**" location="/resources/" />

I'm accessing the content in jsp like this:

<link href="<c:url value="/resources/css/blueprint/screen.css" />" rel="stylesheet" type="text/css">

Everything I've been reading suggests that I have it all setup correctly however it is not working. I'm using weblogic server and on startup it does map the /resources/ folder.

Any help would be greately appreciated!

aaa-servlet.xml in its entirety:

Answer 1

You are mapping your app to the root context, so you should probably include

<mvc:default-servlet-handler/>

in your mvc config. Have a look at 15.12.5 in the spring docs . I wasn't able to get mvc:resources to work without that setting when my dispatcher servlet was mapped to /. At least, that's what I seem to remember having to do when I configured this a couple of months ago in my project.

Answer 2

Try replacing your <resources mapping="/resources/**" location="/resources/" />

with

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

Answer 3

Got it fixed!

Looks like there is a bug in ResourceHttpRequestHandler which only appears with Weblogic.

To fix the issue:

Remove

<resources mapping="/resources/**" location="/resources/"/>

Add

<default-servlet-handler/>

I know some of you suggested using the default-servlet-handler but the resources mapping must be removed in order for it to work!
