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 .. }
In some class which is annotated with @Configuration annotation.
