How to inject a bean with constructor arguments using @Autowrire

[benze]

Hi,

Is there anyway to use the Autowire annotation to inject a bean which has a constructor into a class using the @Autowire annotation?

In XML, it is easy to configure the bean information with <constructor-args>, but is there any way to do something similar using the annotation?

Thanks,

Eric

You mean if the @Autowired annotation can be applied on constructors?

public class Sample {
    private A a;

    @Autowired
    public Sample (A a) {
        this.a= a;
    }
}

No. Actually, I meant more as a class member:

Ex:

@Component
public class MyConstructorClass{

  String var;
  public MyConstructorClass( String var ){
    this.var = var;
  }
...
}


@Service
public class MyBeanService{
  @Autowired
  MyConstructorClass myConstructorClass;

  ....
}

In this example, how do I specify the "String var" variable required by MyConstructorClass. If I was using an XML configuration file, I'd be able to use <constructor-args> to specify the value, but how do I do that with the @Autowire annotation?

Thanks,

Eric

Sorry to make this shameless bump, but I'm really stuck on this issue and was really hoping that someone could help me out here. Is there no way to Annotation autowire a bean that requires constructor arguments?

Thanks,
