用户类的配置:
<class name="User" table="users" lazy="false">
<id name="id" column="id">
<generator class="native"/>
</id>
<property name="type" column="type"/>
<many-to-one name="parent" column="parent"/>
<property name="loginName" column="login_name" unique="true" not-null="true" index="idx_users_login_name" length="50"/>
<property name="name" column="name" length="50"/>
<property name="password" column="password"/>
<property name="email" column="email" length="50"/>
<property name="locale" column="locale" length="20"/>
<property name="locked" column="locked"/>
<many-to-one name="metadata" column="metadata_id"/>
<set name="userSpaceRoles" cascade="all" inverse="true" lazy="false">
<key column="user_id"/>
<one-to-many class="UserSpaceRole"/>
</set>
</class>
,而MeetingItem类是:
<class name="MeetingItem" table="meeting_item">
<id name="id" column="meeting_item_id" type="long">
<generator class="native"/>
</id>
<property name="summary" column="summary" type="string"/>
<property name="detail" column="detail" type="string"/>
<many-to-one name="space" column="space_id"/>
<property name="date" column="date" type="date"/>
<list name="users" cascade="all" lazy="false">
<key column="meeting_item_id"/>
<index column="idx"/>
<one-to-many class="User"/>
</list>
</class>
问题是我得到了例外:
org.hibernate.MappingException: Association references unmapped class: info.domain.User
at org.hibernate.cfg.HbmBinder.bindCollectionSecondPass(HbmBinder.java:2380)
at org.hibernate.cfg.HbmBinder.bindListSecondPass(HbmBinder.java:2231)

at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:140)
列表的映射正在产生问题。我做错了什么?
编辑:
这两个配置位于不同的文件中,如果这两个配置放在同一个xml中,则问题不会发生。
答案 0 :(得分:3)
请添加对映射文件的引用(将info.domain.User
映射到hibernate.cfg.xml。

请添加类级别注释以将类注册为Spring bean,即@Entity,因为您没有使用xml配置。
