==================================
两个表Menu，
 <set name="menuRoles" inverse="true" lazy="false">
  <key>
  <column name="menuID" not-null="true" />
  </key>
  <one-to-many class="com.sj.qh.entity.MenuRole" />
  </set>
MenuRole
 <many-to-one name="role" class="com.sj.qh.entity.Role" fetch="select" lazy="false">
  <column name="ROLE_ID" not-null="true" />
  </many-to-one>
  <many-to-one name="menu" class="com.sj.qh.entity.Menu" fetch="select" lazy="false">
  <column name="menuID" not-null="true" />
  </many-to-one>

XML code

<many-to-one name="role" class="com.sj.qh.entity.Role" fetch="join" lazy="false">
  <column name="ROLE_ID" not-null="true" />
  </many-to-one>
  <many-to-one name="menu" class="com.sj.qh.entity.Menu" fetch="join" lazy="false">
  <column name="menuID" not-null="true" />
  </many-to-one>
fatch改成join试试
