Olá pessoal!

Pessoal, como faço o relacionamento sendo que, um Usuario pode ter vários DadosUsuario?

@Entity
@Table(name="usuario", schema="teste")
public class Usuario implements Serializable{

    @Column(name = "nome")
    private String nome = "";

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    @OneToMany(cascade=CascadeType.ALL, mappedBy="usuario")
    private Usuario usuarios;

    
    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public Usuario getUsuarios() {
        return usuarios;
    }

    public void setUsuarios(Usuario usuarios) {
        this.usuarios = usuarios;
    }
}
@Entity
@Table(name="dadosusuario", schema="teste")
public class DadosUsuario implements Serializable{

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    @Column(name="dado")
    private String dado = "";

    @Column(name="usuario_id")
    private int usuario_id = 0;

    @ManyToOne
    @JoinColumn(name="usuario_id", nullable=false)
    private DadosUsuario dadosusuarios;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getDado() {
        return dado;
    }

    public void setDado(String dado) {
        this.dado = dado;
    }

    public int getUsuario_id() {
        return usuario_id;
    }

    public void setUsuario_id(int usuario_id) {
        this.usuario_id = usuario_id;
    }

}[/code]

tenho o mapeamento:
[code]<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/teste</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">123</property>
    <mapping class="modelo.Usuario"/>
    <mapping class="modelo.DadosUsuario"/>
  </session-factory>
</hibernate-configuration>[/code]
