if 2 class implements same interface and now i planned to add both the component in ioc java

The use of @Qualifier will solve the issue.

Explained as below example :

public interface PersonType {} // MasterInterface

@Component(value=”1.2″)

public class Person implements  PersonType { //Bean implementing the interface

@Qualifier(“1.2″)

    public void setPerson(PersonType person) {

        this.person = person;

    }

}
@Component(value=”1.5”)

public class NewPerson implements  PersonType {

@Qualifier(“1.5”)

    public void setNewPerson(PersonType newPerson) {

        this.newPerson = newPerson;

    }

}
Now get the application context object in any component class :
Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id
you can the object of class of which qualifier id is passed.
