我正在尝试使用休眠进行一对一映射以将一些信息插入数据库,但每次尝试时都会出现此错误。

这是我的 client.hbm.xml 文件。
<hibernate-mapping>
<class name="register.Client" table="client" lazy="false">
<id name="clientId" type="string" column="CLIENT_ID"
length="255">
<generator class="increment"></generator>
</id>
<property name="address" type="string" column="ADDRESS"
length="255" />
<property name="email" type="string" column="EMAIL"
length="255" />
<property name="username" type="string" column="USERNAME"
unique="true">
</property>
<!-- Associations -->
<!-- bi-directional one-to-one association to Login -->
<one-to-one name="login" class="login.UsrPwd" lazy="false"
outer-join="auto" />
</hibernate-mapping>
这是我的 login.hbm.xml 文件
<hibernate-mapping>
<class name="login.UsrPwd" table="login">
<id name="username" type="string" column="USER_NAME"> </id>
<property name="password" column="PASSWORD" type="string"/>
<property name="type" column="TYPE_ID" type="int"></property>
<one-to-one name="consultantInfo" class="register.ConsultantInfo"
cascade="all" />
<!-- bi-directional one-to-one association to Client -->
<one-to-one name="client" class="register.Client" cascade="all"/>
</class>
</hibernate-mapping>
当我运行我的函数将信息添加到数据库时,这是我得到的 SQL。
Hibernate: insert into login (PASSWORD, TYPE_ID, USER_NAME) values (?, ?, ?)
Hibernate: update client set ADDRESS=?, EMAIL=?, USERNAME=? where CLIENT_ID=?
我不认为第二个应该是更新的,因为该行还不存在,这就是它抛出我得到的异常的原因。我不知道它为什么这样做,任何帮助将不胜感激。
如果您需要更多信息,请告诉我,我可以提供
