Struts2 integration with Spring Security

[Soheil Tayari]

I'm new to Spring Security and I wanted to use it for authentication purposes in my Struts2 application. The problem is that when I define Struts2 filter and Spring Security filter in web.xml and run the application I get the error 404. Both filters are mapped to /* url pattern so I suspect that might be the problem cause when I remove the Spring Security filter Struts2 works fine and I get to my home page. Here is my web.xml file:

...

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml, /WEB-INF/applicationContext-security.xml</param-value>
    </context-param>

    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
        <init-param>
            <param-name>actionPackages</param-name>
            <param-value>application</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

...

</web-app>

Are you sure context configuration file lives in WEB-INF rather than WEB-INF/classes?
Could be that Spring isn't finding it.

Yes it's in WEB-INF.

I think I fixed it. The problem was that I missed some libraries in the classpath. I kept adding libraries that was missing according to container log file till it stopped complaining :-).

Gerat news!

With projects I'm invovled with that don't use Maven, libraries can be a pain.
If you can, look in to Maven. Maven will manage most of your libraries and dependencies for you.

Netbeans has a project template for a Maven Web Application. I love it!
I haven't done it in Eclipse...

Thanks Chris. I will definitely do that.
