我为用户和管理员提供了两个rolle服务，具有这些接口：

package employee.service;

import employee.model.EmployeeDiv;
import employee.model.EmployeeInfo;
import employee.model.UserInfo;

import java.util.List;

/**
 *
 * @author serge
 */

public interface AdminService extends UserService {

     //  !!!! for register & udate of Employee use String type birthday !!!!

    /*
     * Employee
     */
    public EmployeeInfo registerEmployee(EmployeeInfo employeeInfo);

    public EmployeeInfo updateEmployee(EmployeeInfo employeeInfo);

    public EmployeeInfo findEmployeeByID(Integer id);   

    /*
     * Division
     */
    public EmployeeDiv registerDivision(EmployeeDiv division);

    public EmployeeDiv updateDivision(EmployeeDiv division);

    public List<EmployeeDiv> findAllDivisions();

    public List<EmployeeDiv> findDivisionsByName(EmployeeDiv division);

    public EmployeeDiv findDivisionsById(Integer id);

    /*
     * Login
     */
    public UserInfo registerUser(UserInfo user);

    public UserInfo updateUser(UserInfo user);

    public List<UserInfo> findAllUsesrs();

    public List<UserInfo> findUsesrByLogin(UserInfo user);

    public UserInfo findUsesrById(Integer id);
}

这是AdminServiceImpl：
