Re: Autowired and PostConstruct with Struts + Spring
How is your JUnit test setup? If your service is injected in your JUnit test
and not in Struts then it could be that contextConfiguration in web.xml is
messed up.
I usually annotate the action with @Component and just put an @Autowired
over the setter. I am not sure what @PostConstruct does.

Re: Autowired and PostConstruct with Struts + Spring
Wow. I really shouldn't try to help people when I am on a diet. My brain does
not work.
Get rid of the @PostExecute and change that method to execute. You should be
able to set a break-point within your execute method and see that myService has
been initialized.
My struts action contains :
@Autowired
private MyService myService
public String execute() {
// use here myService
}

I have a question. Why are you using PostConstruct anyway? AFAIK, a new
action is created for each request. This is not going to work like a servlet
where it is created, you perform some initialization. I think the problem is
caused by the mixing of APIs.
My guess is that whatever you are trying to do in the @PostConstruct annotated
method should be in your annotate.

Hi Norris and Dave!
Thank you for your answers.
Yes, I have get/set methods for myService.
If you means declaring:
in my struts.xml for my object factory, yes. I don't have @Component for Spring
injection, but I suppose Spring work well as far as the myService bean is
available in my context for other beans in my app.
I'm just wondering about @Autowired and @PostConstruct behaviour when passing
by Struts + Spring.
Probably @PostConstruct is executed just before the @Autowired?
Using pure Spring without Struts works well: running a JUnit test with my
@PostConstruct annotated method show myService is not null, but when this is in
a Struts action does not work...
Has anybody see this behaviour?
Thank you for your help!

Re: Autowired and PostConstruct with Struts + Spring
Check you only have one ocurrence of "myService" in your spring
configuration specially if it's in more than one file. Maybe there is
more than one instance and spring uses the "last wins" design
principle.

Re: Autowired and PostConstruct with Struts + Spring
Did you set Spring to be your object factory in your struts.xml. If you used
Spring annotations, did you annotate your bean to be injected with @Component
and designate a base package for Spring to scan for beans?

Hello everybody!
I'm trying to use my service into a Struts action but with no success.
My struts action contains :
@Autowired
private MyService myService
@PostConstruct
public void init() {
// use here myService
}
Unfortunately myService is always null and I cannot use myService in the init()
method...
The bean myService should correctly declared in my application-context.xml:
...
and my struts.xml contains:
Where I'm wrong?
Many Thanks!
