I am trying to understand the various Spring bean configurations, and at the outset, trying the traditional XML way.
Now I came to know for dependency injection,the "basic" methods are setter injection and constructor injection.
Thus far, good.
I also came to know that one more method which Spring provided is by Autowire. In Autowire we have many options, like: byType, byName, constructor.
Now when I dig more about Autowire option , it seems that for byType and byName to work there needs to have setter method to be present while for Autowire by constructor there should be matching constructor.
Is this correct?
Now, if Autowire internally uses constructor or setter, then why do we have this option present at all?
Can anyone help me understand this?
