Available in two ways:
1. Primary key association
[Main]: one-to-one
[From]: one-to-one constrained = "true" name = "@ PP"
Master key ID: generator-class = "foreign" generator-param name = "prot" value = "@ pp"
2. The only foreign key association
[Main]: Many-to-one unique = "true" name = "@ P1"
[From]: One-to-one property-ref = "@ p1" (no two-way can omit this property)
.
Station (must have a getDetail property)
/ ** * Modify STATIONDETAIL ID generated policy to foreign * @ hibernate.one-to-one cascade = "all" * / public stationdetail getdetail () {return detail;}
STATIONDETAIL (must have a getStation property)
/ ** * @Hibernate Property = "ID" * @ hibernate.id * column = "* unsaved-value =" - 1 "* generator-class =" foreign "* @ hibernate.generator-param name =" Property "value =" station "station is the attribute of the foregoing * / public long getId () {return ID;}
/ ** * constrained = "true" means using this property as the primary key * @ hibernate.one-to-one constrained = "true" name = "station" * @Return * / public station getstation () {return station;}

ID generation uses native, if you don't need a two-way association, you can do not need.

SQL
Create Table T_Station_Detail (ID Bigint Not Null Auto_Increment, Address Text, Email Varchar (255), Fax Varchar (255), Introduce Text, Tel Varchar (255), Primary Key (ID))
Create Table T_Station (ID Bigint Not Null Auto_Increment, Code Varint Unique, Name Varchar (255), Primary Key (ID))
ALTER TABLE T_STATION Add Index FK4A7DF4695C5811BC (station_detail), add constraint fk4a7df4695c5811bc foreign key (station_detail) References T_Station_Detail (ID)
