mybatis嵌套查询，resultMap不匹配，大神帮我看看

Question

这是实体类：
private int employeeId;
private String employeeNum;
private String employeePass;
private String personName;
private String employeeGender;
private Positions employeePosition;
private Department employeeDepartment;
private Site employeeSite;

这是mappper：
<resultMap type="Employee" id="employeeMap">
<id property="employeeId" column="employeeId"/>
<result property="employeeNum" column="employeeNum"/>
<result property="employeePass" column="employeePass"/>
<result property="personName" column="personName"/>
<result property="employeeGender" column="employeeGender"/>
 <association property="employeePosition" javaType="Positions" column="employeePosition" select="org.carabmer.dao.PositionsDao.positionQuery">
 <id property="positionId" column="positionId"/>
<result property="positionName" column="positionName"/>
</association>
<association property="employeeSite" javaType="Site" column="employeeSite" select="org.carabmer.dao.SiteDao.siteQuery">
<id property="siteId" column="siteId"/>
<result property="siteAddress" column="siteAddress"/>
<result property="siteUsed" column="siteUsed"/>
</association>
        <association property="employeeDepartment" javaType="Department" column="employeeDepartment" select="org.carabmer.dao.DepartmentDao.departmentQuery">
            <id property="departmentId" column="departmentId"/>
            <result property="departmentName" column="departmentName"/>
</association>
    </resultMap>


这是异常：
 No constructor found in org.carabmer.model.Employee matching [java.lang.Integer, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.Integer, java.lang.Integer, java.lang.Integer]

 按理来说返回的属性应该是department等类型，可是还是返回int类型，resultMap还不是很熟悉，大神帮我看看，急

Answer 1

resultMap返回的是employeeMap,你这实体里面存在对象,需要重新写个map
