联(复)合主键问题

key-many-to-one name="nodeId" class="AlmNodeDefinition" column="NODE_ID"/>
        <key-many-to-one name="userId" class="AlmUser" column="USER_ID"/>
把class="AlmNodeDefinition"  class="AlmUser"  去掉。 。你这毛的联合主键 
还有字段名请用小写。。看都懒得看
<class name="com.unicap.objects.manpower.WorkScheme"
table="tb_work_scheme">
<composite-id name="primaryKey"
class="com.unicap.objects.manpower.WorkSchemePK">
<key-property name="userName" column="user_name" />
<key-property name="workDate" column="work_date" />
<key-property name="statementID" column="statement_id" />
</composite-id>
</class>hibernate里这么写。。自己看吧
