java – 抽象类的自动连接依赖项注入失败

我有以下类结构

public interface GenericDAO<T> {

    public void create(T entity);
    public void update(T entity);
    public void delete(T entity);
}

DAO班

public interface EmployeeDAO extends GenericDAO<Employee>  {

    public void findEmployee(EmployeeQueryData data);
}

DAO实现类

@Repository("employeeDAO")
public abstract class EmployeeDAOImpl implements EmployeeDAO {

protected EntityManager entityManager;

@Override
public void findEmployee(EmployeeQueryData data) {

...... code

}

我面临的问题是当我尝试部署时,我得到以下异常.
如果我从EmployeeDAOImpl中删除摘要并删除扩展GenericDAO< Employee>从EmployeeDAO然后应用程序部署没有错误.因此,不可能为EmployeeDAOImpl提供抽象类,或者我需要在没有抽象的DAO实现中实现GenericDAO的所有方法？

Error creating bean with 
name 'employeeService': Injection of autowired dependencies failed; \
nested exception is org.springframework.beans.factory.BeanCreationException:
Could not autowire field: test.dao.EmployeeDAO

GenericDAOImpl

public class GenericDAOImpl<T> implements GenericDAO<T> {    

    public void create(T entity) {
    }       
    public void update(T entity) {
    }
    public void delete(T entity) {
    }

EmployeeDAOImpl

public class EmployeeDAOImpl extends GenericDAOImpl<Employee> implements EmployeeDAO {
