<resultMap type="com.tsy.springmvc.model.system.Employee" id="ClassResultMap">
        <id property="employeetID" column="employee.employeeID"/>
            <result property="employeetName" column="employee.employeeName"/>
            <result property="depatmentID" column="department.departmentID"/>
            <result property="departmentName" column="department.departmentName"/>
    </resultMap>
    <select id="selectALLEmployee" resultMap="ClassResultMap">
        select employee.employeeID, employee.employeeName, department.departmentID, department.departmentName
        from employee, department
        where employee.departmentID = department.departmentID
    </select>结果已经映射,但是Controller控制层怎么获取这个 List<Employee>是在对应的Service提供方法,Impl实现嘛? 怎么实现?
