Hibernate集合映射

Question

我有點迷路了Hibernate集合映射。嘗試添加拋出以下在Eclipse Hibernate的角度來看，持久性配置：

Invalid ORM mapping file. 
Error parsing XML (line14 : column 16): The content of element type "list" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(index|list-index),(element|one-to-many|many-to-many|composite-element|many-to-any),loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?,filter*)". 
Error parsing XML (line17 : column 15): The content of element type "map" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(map-key|composite-map-key|map-key-many-to-many|index|composite-index|index-many-to-many|index-many-to-any),(element|one-to-many|many-to-many|composite-element|many-to-any),loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?,filter*)". 

實際映射配置如下：

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

<hibernate-mapping>

     <id name="serverId" type="java.lang.Integer">

      <generator class="identity" /> 
     </id> 
     <list name="sessions" inverse="true"> 
      <key column="serverID" not-null="true"/> 
      <list-index column="SERVER_SESSION_NUMBER" />

     </list> 
     <map name="users" inverse="true">

      <map-key type="string" column="SERVER_USER_NUMBER"/> 
      <one-to-many class="core.User"/> 
     </map> 
    </class> 
</hibernate-mapping>

      <list-index column="USER_SESSION_NUMBER" />

感謝您的幫助！

Answer 1

訂單是特定的（並在錯誤消息中給予您）。這不是休眠的事情，它是一個XML模式的東西。

因此，獲得正確的標籤的順序，如： <列表索引>需要是前<一個一對多> 等

編輯： 並非所有的表都是錯誤的。第一個是好的。第二個有兩個錯誤，應該是

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

<hibernate-mapping> 
    <class name="core.User" table="user" schema="imdb"> 
     <id name="userId" type="java.lang.Integer"> 
      <column name="USER_ID" /> 
      <generator class="identity" /> 
     </id> 
     <property name="login" column="LOGIN" type="string" />   
     <property name="online" column="ONLINE" type="boolean" /> 
     <property name="last_message" column="LAST_MESSAGE" type="string" /> 
     <property name="newmessage" column="NEW_MESSAGE" type="boolean" /> 
     <list name="sessions" inverse="true"> 
      <key column="USER_ID" not-null="true"/> 
      <list-index column="USER_SESSION_NUMBER" /> 
      <one-to-many class="core.Session"/>   
     </list> 
     <many-to-one name="serverID" column="SERVER_ID" class="core.Server"/> 
    </class> 
</hibernate-mapping> 

你的第三個是錯誤的，因爲它下課=「core.User缺少一個報價 - 並且應該

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

<hibernate-mapping> 
    <class name="core.Session" table="session" schema="imdb"> 
     <id name="sessionID" type="java.lang.Integer"> 
      <column name="SESSION_ID" /> 
      <generator class="identity" /> 
     </id> 
     <many-to-one name="serverID" column="SERVER_ID" class="core.Server"/> 
     <many-to-one name="userID" column="USER_ID" class="core.User"/> 
    </class> 
</hibernate-mapping>
