The actions are auto-wired by name by default - so if any of its properties=
 match bean-ids in your spring config, and they have setters, then those pr=
operties will get set.

The part about declaring the dependencies means you disable the auto-wiring=
, and declare your actions as spring beans. So, instead of this:

        <action name=3D"index"
            class=3D"com.actions.IndexAction">
            <result>/WEB-INF/view/index.jsp</result>
        </action>

You would do this:

        <action name=3D"index"
            class=3D"index-action-id">
            <result>/WEB-INF/view/index.jsp</result>
        </action>

Along with additional spring config:

    <bean id=3D"index-action-id"
        class=3D"com.actions.IndexAction">
        <property name=3D"myDao" ref=3D"myDao-id" />
        <property name=3D"myMailSender" ref=3D"myMailSender-id" />
    </bean>

Notice this does not actually disable auto-wiring (you would have to set th=
e auto-wire attribute in the spring config, either globally or per-bean), b=
ut it does declaratively state what to set on the action as properties.

Subject: Injecting Spring Services into Struts 2 Actions

=20
Hello,
=20
I found this guide to injecting Spring beans into Struts 2 Actions:
=20
http://cwiki.apache.org/WW/spring.html
=20
According to the red box at the bottom of the document, the Struts 2 Action=
 does not need to be registered with Spring.  So far so good.
=20
However, I'm a little unclear as to how exactly it "knows" what Spring bean=
s to inject into the Struts 2 Action.  Assuming I have a Struts 2 Action th=
at depends on a PersonService, I assume that the Struts 2 Action would have=
 a public mutator for the PersonService like this:
=20
public void setPersonService(PersonService service) {
    this.personService =3D service;
}
=20
How does the injection system "know" that this method should be used for in=
jecting a Spring bean?  Imagine that the Struts 2 Action has several "set" =
methods, and that there are a number of configured Spring beans.
It would take way too long for the injection system to look through every "=
set" method on the Action and try to find a matching Spring bean, especiall=
y if there are a lot of Spring beans (and there usually are).
=20
The document above includes this comment:
=20
We strongly recommend that you find declarative ways of letting Spring know=
 what to provide for your actions.
=20
But it doesn't give an example of how to let Spring know what to provide to=
 the actions.
=20
So, the question is:  How do I tell Spring what beans need to be injected i=
nto the Action?
=20
Thanks!!!!
