一、代码

映射domain为继承关系

public class CocTreeNode extends CocBean implements TreeNode<CocTreeNode> {  private String level1, level2;  public void setLevel1(String level1){...}  public void setLevel2(String level2){...}  public String getLevel1(){...}  public String getLevel1(){...}}public class CocBean {  protected String name;  protected Double volume;  public void setName(String name){...}  public void setVolume(Double volume){...}  public String getName(){...}  public Double getVolume(){...}}

二、映射xml文件

利用resultMap的extends属性。

<resultMap id="CocBeanResult" type="CocBean">    <result property="name" column="NAME"/>    <result property="volume" column="VOLUME"/></resultMap><resultMap id="simpleRow" type="CocTreeNode" extends="CocBeanResult">    <result property="level1" column="LEVEL1"/>    <result property="level2" column="LEVEL2"/></resultMap>
