Depedency injection doesn't work with generate-resources #43

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

Depedency injection doesn't work with generate-resources. I didnt search much 
about why but it seems that the pattern ResourceCollection/resource brake it. 
If you only make a one Resource class it will get injected.

What version of the product are you using? On what operating system?
0.4 and 0.5

May I ask why do you want to DI resource class instances somewhere? Or do I get 
that wrong? Resources should only be accessed by the JAX-RS runtime.

Or do you mean something like 
http://code.google.com/p/grails-jaxrs/wiki/AdvancedFeatures#Service_injection 
for generated resources?

ResourceCollection instanciate Resource

Ah ok. Will take a look.

In generated resources, I plan to delegate all CRUD actions to a (generated) 
service class. The generated service is then used by the Resource and 
ResourceCollection classes. This means that the actual CRUD work is done inside 
service methods which allows better control over transaction boundaries and you 
can also inject any additional dependencies into that service. 

Would this fit your needs?

Alternatively, you can still autowire dependencies into CollectionResource 
classes and pass them as arguments to the Resource constructor if you want 
(which requires a little modification to the generated code though).

An example how to do programmatic dependency injection with Grails is described
