annotation 与xml 多表映射关系

一(Group)对多(User)：

Annotation 声明映射文件(Group)：

@Entity
@Table(name="t_group")
public class Group {
<wbr>private int id;<br><wbr>private String name;<br><wbr>private Set&lt;User&gt; users = new HashSet&lt;User&gt;();<br><wbr>@Id<br><wbr>@GeneratedValue<br><wbr>public int getId() {<br><wbr><wbr>return id;<br><wbr>}<br><wbr>public void setId(int id) {<br><wbr><wbr>this.id = id;<br><wbr>}<br><wbr>public String getName() {<br><wbr><wbr>return name;<br><wbr>}<br><wbr>public void setName(String name) {<br><wbr><wbr>this.name = name;<br><wbr>}<br><wbr>@OneToMany<br><wbr>@JoinColumn(name="groupId")<br><wbr>public Set&lt;User&gt; getUsers() {<br><wbr><wbr>return users;<br><wbr>}<br><wbr>public void setUsers(Set&lt;User&gt; users) {<br><wbr><wbr>this.users = users;<br><wbr>}<br> }<br></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
