In spring Container How @Autowire can track which dependancy to inject in setter Method

I can understand how @Autowired can track the the dependency of the value.How they identify which setter method to invoked in run-time using reflection. And set the value in appropriate method.

I want to understand internal code implementation of @Autowired. How they can work internally. I can also read this raw code BeanWapper & AbstractAutowireCapableBeanFactory but I do not understand the actual implementation of @Autowired.

I can Refer these :-
