Why @PetiteInject cannot inject service in DecoraManager?












1















I have a DecoraManager implementation : AppDecoraManager, and want to inject a service e.g.: FooService as:



@PetiteInject
FooService fooService;


When resolveDecorator() is called I want to use fooService to determine some parameters, but it has null value.



What could be the reason for this, and how could I resolve it?

          DecoraManager is created by the servlet container, in DecoraServletFilter.



          At the moment, there is no integration with existing Petite IOC, so you have to do the following:




          • First, you need to have a public static reference to PetiteContainer. Store it during the creation of container, for example.

          • Override createDecoraManager() in your implementation

          • Use PetiteContainer.wire(this) in your implementation of DecoraManager.


          That is the only way to do so, so far.



          The alternative would be this:




          • Register DecoraManager as @PetiteBean.

          • Again, get the static reference to PetiteContainer

          • In createDecoraManager use PetiteContainer.get() to get the instance.


          In the first example, DecoraManager gets just wired; in the second example, it gets stored in Petite container, too.
