hibernate如何配置联合主键

将id写成 <composite-id>然后把配置写在下面就可以了

 

<composite-id>
              <key-property name="code" type="java.lang.String">
                <column name="chirasi_code" length="50"></column>
             </key-property>
             <key-property name="name" type="java.lang.String">
                <column name="block_name" length="50"></column>
             </key-property>
  </composite-id>
