Plexus Plugin

This plugin got marked as deprecated since Struts 2.6!

While Plexus is similar to other inversion-of-control (IoC) or dependency injection frameworks such as the Spring Framework, it’s fully-fledged container supports many more features.

The Plexus plugin enables Struts Actions, Interceptors, and Results to be created and injected by Plexus.

This plugin provides an ObjectFactory implementation that tries to create Struts Action, Interceptor, and Result classes as Plexus objects.



To use the plugin, when configuring Struts Actions, Interceptors, or Results in struts.xml, set the class attribute to contain the Plexus object id, rather than the actual Java class. This will allow Plexus to create the object and inject any dependencies also managed by Plexus.


A simple Action using a Plexus id

<action name="myAction" class="myPlexusId">


The following settings can be customized. See the developer guide.

Setting Description Default Possible Values
struts.objectFactory The name or class name of the ObjectFactory implementation to use plexus plexus, struts, or any class that extends ObjectFactory
