Struts 2 interceptor and spring problem
Hello. I am in the process of migrating my application from webwork
2.2.x to Struts 2 and have encountered a problem. I have a custom
interceptor which has a member variable injected by Spring. This
object is a request scoped bean which is contructed using a factory
method from another bean which is a singleton. So, it looks like
something like this:
MyInterceptor
-->private RequestBasedBean rbb
--> @required
void setRequestBasedBean
in applicationContext.xml:
<bean id="factory" class="com.blah.mypackage.myclass" scope="singleton">
<bunch of stuff here>
</bean>
<bean id="sessionFactory" factory-bean="factory" factory-method="getFactory"
scope="singleton"/>
<bean id="requestBasedBean" factory-bean="sessionFactory"
factory-method="openSession" destroy-method="close" scope="request"
/>
This worked fine in webwork, but in struts 2, it looks like it is
trying to construct MyInterceptor at startup time and failing because
when it injects the requestBaseBean, there is no request context and
it fails (Stack trace below). Note that I am using a request-scoped
bean and it is sort of referred to by a singleton, but I don't think I
need to use a scoped-proxy (which fails anyways, I tried it). Again,
this worked fine in the WebWork implementation. So, I'm trying to see
a) what changed with struts 2 interceptor intialization.
b) if it isn't technically a struts 2 problem, what workaround exist
in Spring (I may take this to the spring forums if this is not an
issue around struts 2).
Thanks! And there is a reason why there are all the singletons and
factory stuff. Related to legacy support and non-spring aware code.

Posted by Steve C <st...@gmail.com>.
BTW, I did see this:
https://issues.apache.org/struts/browse/WW-1576
but i'm using struts 2.0.8 and the xwork version is 2.0.3. Is this
still an xwork problem that I should ask about on opensymphony?
