Hibernate One-to-many Unidirectional Mapping

Group-user:one to many

In group class, we had a set<user> users to store User;

1.Annotation

@Entity @table (name= "X_group") Public classGroup {Private intID; PrivateString name; //For one-to-many illustration    PrivateSet<user> users=NewHashset<user>(); @Id @GeneratedValue Public intgetId () {returnID; }         Public voidSetId (intID) { This. ID =ID; } @OneToMany @JoinColumn (name= "GroupId")     PublicSet<user>getusers () {returnusers; }     Public voidSetusers (set<user>users) {         This. Users =users; }      PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }} @Entity @table (name= "X_user") Public classUser {Private intID; PrivateString name; @Id @GeneratedValue Public intgetId () {returnID; }         Public voidSetId (intID) { This. ID =ID; }     PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }}

2.XML

package = "Com.hibernate.model" ><class name= "Group" table= "T_group" >   <id name= "id "></id>    <property name=" name "></property>    <set name=" Users ">      <key Column= "GroupId" ></key>      class= "Com.hibernate.model.User"/>    </set></  Classpackage = "Com.hibernate.model" ><class name= "User" table = "U_user" >   <id name= "id" ></id>    <property name= "Name" ></property></class>
