Hibernate中多主键对象映射配置

 

本身多主键配置

<composite-id><key-property name="xkkh" type="java.lang.String"><column name="xkkh" length="20" not-null="true"/></key-property><key-property name="skdx" type="java.lang.String"><column name="skdx" length="20" not-null="true"/></key-property></composite-id>

 

多主键many-to-many映射配置：多主键用<key>标签中的<columu>标签表示

 

<set name="teacherBeans" table="KK_JS_VIEW" schema="ZFXFZB"><key><column name="xkkh"/><column name="skdx"/></key><many-to-many class = "TeacherBean" column="jszgh"/></set>

many-to-one

<many-to-one name="kkBean" class="edu.dzu.sjjw.entity.KkBean" insert="false" update="false"><column name="xkkh"/><column name="skdx"/></many-to-one>
