Question

hibernate联合主键做外键时两个many-to-one中有相同属性怎么办？

下面的例子不是真实案例（请勿纠结），但意思相同。
<many-to-one name="student" class="org.apache.dream.common.entity.Student">
<column name="STUDENT_ID" />
<column name="CLASS_NO" />
</many-to-one>
<many-to-one name="teacher" class="org.apache.dream.common.entity.Teacher">
<column name="TEACHER_ID" />
<column name="CLASS_NO" />
</many-to-one>
这时会报错：
org.hibernate.MappingException: Repeated column in mapping for entity: org.apache.dream.common.entity.XXXXXX.XXXXXX column: CLASS_NO (should be mapped with insert="false" update="false")
<class name="XXXXX" table="t_XX">
<id name="id">
<generator class="native"></generator>
</id>
<many-to-one name="student" class="org.apache.dream.common.entity.Student">
<column name="STUDENT_ID" />
<column name="CLASS_NO" />
</many-to-one>
<many-to-one name="teacher" class="org.apache.dream.common.entity.Teacher">
<column name="TEACHER_ID" />
<column name="CLASS_NO" />
</many-to-one>
</class>

这个需要你定义哪一方是维护方！

追问

您好！我刚才把问题完善了下，请再看下，两个many-to-one
都是与另一个类关联。因为有字数限制，而且格式也有点乱了，所以
