DAO not getting injected, using springbean

Hello.

I have created a new small project to try to figure out how to use the 
SpringBean, Service, and Repository annotations with Wicket, Spring, 
Hibernate, Maven and Eclipse.

However, I am getting an error with a user DAO that I have created.

I have a service that is using the dao tagged as @Service, I have the 
DAO in the service tagged with @SpringBean, and the DAO code itself is 
tagged with @Repository.  The service that is using the DAO is getting 
found correctly.

When I have the InjectorHolder code in the dao constructor, I get an 
error that says 'InjectorHolder has not been assigned an injector'

When I comment out the InjectorHolder line in the dao constructor, the 
DAO is null, and getUserDAO throws an exception.

Since I am not certain that I can attach files, I will insert the 
relevant code and exceptions into this email.

Any pointers you can give would be greatly appreciated.

Thanks very very much,

Bruce.

Re: Re: Re: Re: Re: DAO not getting injected, using springbean

Posted by Bruce McGuire <br...@coastware.com>.

Hi James.

It turns out that I had 'userDAO' in one spot, and 'UserDAO' in another. 
Problem solved.

Thanks,

Bruce.

Re: Re: Re: Re: DAO not getting injected, using springbean

Posted by Bruce McGuire <br...@coastware.com>.

Hi Vasu.

Thanks for the info. Now I get it, and have successfully wired my demo 
app so that it does the job.

Although I did notice that along with the context:component-scan I did 
need to define the beans that I was going to autowire. How did you get 
around this?

    <context:component-scan base-package="com.coastware" />
    <bean id="userDAO" 
class="com.coastware.vProbe.model.dao.hibernate.UserDAOHibernate" />

Other than that, this is a very much reduced context file.

Re: Re: Re: DAO not getting injected, using springbean

Posted by Vasu Srinivasan <va...@gmail.com>.

Using annotations, I have only one line in the spring's
applicationContext.xml --

<context:component-scan base-package="packagename" />

Services are tagged with @Service, Daos are tagged with
@Component("xxxDaoImpl"), Wicket web pages have @SpringBean
(name="<serviceName>")

Within the ServiceImpl, the Daos are tagged with @Autowired.

No other xml config, setter, getter for daos etc.

Works like a charm.

Re: Re: Re: DAO not getting injected, using springbean

Posted by James Carman <jc...@carmanconsulting.com>.

You are correct.  You should only use @SpringBean in your wicket-related
code (components/pages).  Let Spring wire the rest together, however you
want to configure it to do that (with annotations or xml).  You can use
@Autowired to inject your DAOs into your Services.  You just have to make
sure you set up your Spring context so that it takes care of that.

Re: Re: Re: DAO not getting injected, using springbean

Posted by Bruce McGuire <br...@coastware.com>.

Hello James.

So I have completely missed the point of the Repository, Service and 
SpringBean annotations?  I was under the impression that the idea was to 
avoid using a lot of xml in my context files.

If I am understanding correctly, what you and Martijn are saying is the 
following:
Tag the dao and service classes with Repository and Service, and in 
wicket code, tag any use of them with SpringBean. However, in the 
service classes, use the normal xml injection method and get/set to get 
the dao into the service class.

Is this a correct interpretation?

Thanks,

Bruce.

Re: Re: DAO not getting injected, using springbean

Posted by James Carman <jc...@carmanconsulting.com>.

You shouldn't use @SpringBean in your spring-managed beans, only in
your Wicket code.  You don't want view-specific code in your "domain"
code.

Re: Re: DAO not getting injected, using springbean

Posted by Bruce McGuire <br...@coastware.com>.

Hi Martijn.

Thanks for the quick response.

Are you saying that the dao and the service should have the 
InjectorHolder code, rather than the @Repository and @Service tags?

Bruce.

Re: DAO not getting injected, using springbean

either call InjectorHolder.getInjector().inject(this) in your
constructor or use Salve.
