Spring 3 MVC resources and tag <mvc:resources />

Question

I'm having some problems with the tag (Spring 3.0.5). I want to add images to my web application, but it doesnt work.

Here is part of my beans config:

<mvc:annotation-driven/>
<mvc:default-servlet-handler default-servlet-name="ideafactory"/>
<mvc:resources mapping="/resources/**" location="/, classpath:/WEB-INF/public-resources/" cache-period="10000" />

Trying to add an image in a jsp file:

<img src="<c:url value="/resources/logo.png" />" alt="Idea Factory" />

First of all, I don't know really where to store the resources (src/main/resources/public-resources? src/main/webapp/WEB-INF/public-resources?). Secondly, this config does not work, I can't see the image. What's wrong?

Thanks!

EDIT: the solution given here: Spring Tomcat and static resources and mvc:resources doesn't work either... Added without success.

EDIT 2: I tried to remove the mvc:resource tag and let only the mvc:default-servlet-handler> one, gave me infinite loop and stackoverflow... o_O (Serving static content with Spring 3)

Found the error:

Final xxx-servlet.xml config:

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

Image in src/webapp/resources/logo.png

Works!

<mvc:resources mapping="/resources/**"
               location="/, classpath:/WEB-INF/public-resources/"
               cache-period="10000" />

Put the resources under: src/main/webapp/images/logo.png and then access them via /resources/images/logo.png.

In the war they will be then located at images/logo.png. So the first location (/) form mvc:resources will pick them up.

The second location (classpath:/WEB-INF/public-resources/) in mvc:resources (looks like you used some roo based template) can be to expose resources (for example js-files) form jars, if they are located in the directory WEB-INF/public-resources in the jar.

Would have helped me, even if it's in fact src/main/webapp/resources/images/logo.png

Ralph Over a year ago

@Nanocom: I introduced the images folder to make it more clear. But the "resources" path of the url is "consumed" by the mvc-tag--mapping, so it must not be in the path of the folder anymore! Except you do it the way you descriped it in your own answer.

As said by @Nancom

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

So for clarity lets our image is in

resources/images/logo.png"

The location attribute of the mvc:resources tag defines the base directory location of static resources that you want to serve. It can be images path that are available under the src/main/webapp/resources/images/ directory; you may wonder why we have given only /resources/ as the location value instead of src/main/webapp/resources/images/. This is because we consider the resources directory as the base directory for all resources, we can have multiple sub-directories under resources directory to put our images and other static resource files.

The second attribute, mapping, just indicates the request path that needs to be mapped to this resources directory. In our case, we have assigned /resource/** as the mapping value. So, if any web request starts with the /resource request path, then it will be mapped to the resources directory, and the /** symbol indicates the recursive look for any resource files underneath the base resources directory.

So for url like http://localhost:8080/webstore/resources/images/logo.png. So, while serving this web request, Spring MVC will consider /resources/images/logo.png as the request path. So, it will try to map /resources to the base directory specified by the location attribute, resources. From this directory, it will try to look for the remaining path of the URL, which is /images/logo.png. Since we have the images directory under the resources directory, Spring can easily locate the image file from the images directory.

So

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

gives us for given [requests] -> [resource mapping]:

http://localhost:8080/webstore/resource/images/logo.png -> searches in resources/images/logo.png

http://localhost:8080/webstore/resources/images/small/picture.png -> searches in resources/images/small/picture.png

http://localhost:8080/webstore/resources/css/main.css -> searches in resources/css/main.css

http://localhost:8080/webstore/resources/pdf/index.pdf -> searches in resources/pdf/index.pdf

You make me waste my time thinking for an hour as to why your answer doesn't work.., its mapping="/resources/**"' not mapping="/resource/**"

Xelian Over a year ago

I am not agree with you. In that situations search in guthub: github.com/…

Plain_Dude_Sleeping_Alone Over a year ago

I mean you declared it as location="/resources/" then mapping="/resource/**"/. Missing s Haha.

Recommendations for resources in order to handle HTTP GET requests for /resources/** by offering static resources in the ${webappRoot}/resources directory is to simply add the following line in the configuration file:

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

It has worked for me.

I also met this problem before. My situation was I didn't put all the 62 spring framework jars into the lib file (spring-framework-4.1.2.RELEASE edition), it did work. And then I also changed the 3.0.xsd into 2.5 or 3.1 for test, it all worked out. Of course, there are also other factors to affect your result.

@Nanocom's answer works for me. It may be that lines have to be at the end, or could be because has to be after of some the bean class like this:

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
<bean class="org.springframework.web.servlet.resource.ResourceHttpRequestHandler" />    

<mvc:resources mapping="/resources/**" 
               location="/resources/" 
               cache-period="10000" />

This worked for me

In JSP, to view the image

<img src="${pageContext.request.contextPath}/resources/images/slide-are.jpg">

In dispatcher-servlet.xml

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