Hibernate mapping Relationship configuration (ii)

Two or one-to-many (unidirectional)

Bean:

 Public classCarImplementsserializable{Private intID; PrivateString name; Privateuser User; ....} Public classUserImplementsSerializable {Private intID; PrivateString name; PrivateSet<car>cars; ....}

XML configuration:

Car.hbm.xml:<classname= "Car">        <!--ID is to configure the primary key name is the attribute in the class and the primary key mapping generator: The Generation policy that represents the primary key -        <IDname= "id">            <Generatorclass= "Native" />        </ID>        <!--property is used to make one by one of the attributes in the class and the fields of the table. -        < Propertyname= "Name" />            </class>User.hbm.xml:<classname= "User">        <!--ID is to configure the primary key name is the attribute in the class and the primary key mapping generator: The Generation policy that represents the primary key -        <IDname= "id">            <Generatorclass= "Native" />        </ID>        <!--property is used to make one by one of the attributes in the class and the fields of the table. -        < Propertyname= "Name" />                <Setname= "Cars"Cascade= "All">            <Keycolumn= "UID" />            <One-to-manyclass= "Car"/>        </Set>    </class>

Annotation configuration:

@Entity Public classCarImplementsserializable{@Id @GeneratedValue Public intgetId () {returnID; }} @Entity Public classUserImplementsSerializable {@Id @GeneratedValue Public intgetId () {returnID; } @OneToMany (Cascade=cascadetype.all) @JoinColumn (name= "UID")     PublicSet<car>Getcars () {returncars; }}
