如何编写自己的逻辑来使用 Unity 初始化属性？

Question

Let's suppose you have Class A and Class B. Both these classes have a private variable:

private Store _store {get;set}

class Class A
{
 private Store _store {get;set}
 constructor()
 {
  init(param1,param2,..);
 }
 init(param1,param2,..)
 {
  //logic to initialize _store
 }
}

class Class B
{
 private Store _store {get;set}
 constructor()
 {
  init(param1,param2,..);
 }
 init(param1,param2,..)
 {
  //logic to initialize _store
 }
}

Problem: duplicate init() code

My Solutions:

1. Simple Factory Pattern: create a StoreFactory class with a Init method that will return a Store instance.
2. Abstract Factory: Create a Abstract Class that has init() method and let Class A and B inherit from it
3. ??

Is there a third way to achieve this? Perhaps with dependency injection container Unity? I would also be interested in knowing any other way of achieving this. With or without unity.

Answer 1

I would avoid the inheritance . Composing is likely to be easier for maintenance in the long run compared to the inheritance , for this reason i will prefer the factory approach or injecting some service into the classes.

Another approach will be to have the Init method as part of the Store class definition. And inject the Store class into the constructors of Class A and B ( Unity will take care of the wiring).
Then you can call the Init method of the Store instead of relying on injecting the factory in each class where the store will be used.
