Ah...I finally figured it out. The bean that wasn't getting injected is in
a spring dispatcher context, NOT the main app context. In other words, I
have:
applicationContext.xml
- this is where the <camelContext> is declared
web.xml:
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
dispatcher-servlet.xml:
<context:component-scan base-package="com.mycompany.controller"/>
The "problem object" is com.mycompany.controller.FooController. It gets
autowired no problem by spring...so it has no trouble depending on beans in
applicationContext.xml. But it's NOT getting injected by camel.
I guess I'm not too surprised now that I think about it. But what do you
think? Is there a way to get camel to wire up dependencies in dispatcher
contexts like this?
If not, I suppose I should just create a separate <camelContext> inside
dispatcher-servlet.xml, but that seems like a waste to me, and could
introduce some "interesting" issues down the line...
Otherwise I guess I'll have to push this particular producer into a bean
that lives in applicationContext.xml, not in the controller itself...hm.
Any ideas?
Thanks,
Dan
