Hibernate映射one-to-one

两个表: 用户表,地址表

T_USER           (主表)
(
  UserID int,  (主键)
  UserName varchar(20)
)

T_ADDRESS   (副表)
(
  UserID int, 
  Province varchar(300),
  City varchar(200)
)

tuser.hbm.xml
....
<one-to-many name="address">                <!--address 为要在TUser类中放Address信息的变量名-->
                          class="tidus.gam.pojo.Address"    <!--class为要address对应的实际的Pojo类,要包含完整包名"-->
                          cascade="all"                           <!--cascade为是否级联,级联:指当此类执行操作时,是否关联对象也执行相同的操作. 如果对本类对象执行delete,那么关联对象也同时delete,这样就保持了数据一致性-->
                          out-join="true"
/>
....

taddress.hbm.xml
....
<one-to-many name="address">    
                          class="tidus.gam.pojo.Address"   
                          cascade="all"    
                          out-join="true"
/>
