What happen when we remove the @Repository in DAO layer in spring?

What happens when we remove the @Repository annotation in DAO layer in spring?

@Repository 
public class EmployeeService {

    // ....

    @Transactional
    public int createEmployee(Employee emp) {
        //create Employee
        employeeDao.createEmployee(emp);

        User user = new User();
        // some fileds of employee are used to create a User
        user.setEmployeeId(emp.getEmployeeId());
        // ....

        userDao.createUser(user);
        // ...
    }
}

You will get: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'employeeService'

@Repository is to create a bean and it indicates that the annotated class is a Repository.

  • Either you can keep @Repository or you can add a bean definition in applicationContext.xml

  • On removing @Repository and no bean specified in applicationContext.xml

    Result: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'employeeService'
