Hibernate 一对一外键映射
------------------------------ ------------------------------
| Users | | Resume |
|----------------------------| FK_USERS |----------------------------|
| UserId number(6) <pk> | <------------- | ResId number(6) <pk> |
| UserName nvchar2(20) | | ResuseRId number(6) <fk> |
| UserPass nvarchar2(20) | | ResName nvarchar2(20) |
------------------------------ | RescardNo nvarchar2(20) |
------------------------------
Resume表的ResuserId外键设为了unique约束，确保每条resume记录具有唯一的ResuserId
在Resume.hbm.xml进行配置
<many-to-one name="users"
class="com.entity.Users"
column="resuserId"
cascade="all"
unique="true"
/>
在Users.hbm.xml进行配置
<one-to-one name="resume"
class="com.entity.Resume"
property-ref="users"
/>
