Setting property via @Value

[bazi]

Hi,

I've tried set the property in the following way:

@Component
public class Empl {

private int age;

public Empl() {}

public Empl( @Value("4") int age ) {
this.age = age;
}

}

It doesn' work. Where am I wrong?

Does anybody know?

Ok,

I know now. You should use @Autowired to indicate a constructor to create bean

Because you had a default constructor on the Empl class. That is the one that would get called by default by the Spring container.
Which is why you had to add @Autowired for the non default constructor.

The thing that I'm not sure about is if you did not have a default constructor would Spring container have called the non-default one?
My guess is probably not, and it would have thrown an exception- no default constructor found.

No. Once you have @Autowired, spring will use the non-default contructor to instantiate the bean. It works this way for me. Comment out your default constructor and try it.
