Why can't we autowire static fields in spring?

Why can't we autowire the static instance variable in the Spring bean. I know there is another way to achieve this but just want to know why cant we do it in below way.

e.g.

@Autowired
public static Test test;

Because when the class loader loads the static values, the Spring context is not yet necessarily loaded. So the class loader won't properly inject the static fields in the bean and will fail.


Because using static fields encourages the usage of static methods. And static methods are evil. The main purpose of dependency injection is to let the container create objects for you and wire them. Also it makes testing easier.

Once you start to use static methods, you no longer need to create an instance of object and testing is much harder. Also you cannot create several instances of a given class, each with a different dependency being injected (because the field is implicitly shared and creates global state - also evil).
