You can write this way

@Repository
class EmployeImplDB{}


@Service   
EmployeImplMetier{

@Autowired
EmployeImplDB myDao;

}

@Repository signifies that your bean is a DAO class

@Autowired injects dao class EmployeImplDB in the Service class

Like this:

@Bean(name = "myDao", initMethod = "init")
public EmployeDao myDao() {
    EmployeDao eidb = new EmployeImplDB();
    return eidb;
}

@Bean(name = "myMetier")
public Metier employeImplDB(EmployeDao myDao) {
    Metier metier= new EmployeImplMetier(myDao);
    return metier;
}

Note: Presuming that name of EmployeImplDB superclass (interface) is EmployeeDB.

is it like this? **com/my/Dao/EmployeImplDB.java** `@Bean(name = "myDao", initMethod = "init") public class EmployeImplDB implements EmployeDao { //my code ... } ` **com/my/service/EmployeImplMetier.java** `@Bean(name = "myMetier") public class EmployeImplMetier extends Metier{ //my code .. } ` – yb3prod Jul 23 '15 at 11:11
In some class which is annotated with `@Configuration` annotation. – Branislav Lazic Jul 24 '15 at 08:17
