Pessoal, preciso de uma ajuda de vocês. Estou tentando fazer um relacionamento tipo ManyToMany no hibernate entre duas classes: Acomodacao e Caracteristica. Abaixo o código das duas classes:
import java.util.HashSet;
import java.util.Set;
import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.ManyToOne;
import br.com.reservason.models.enumeration.StatusAcomodacao;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
@Entity
public class Acomodacao extends BaseEntity {
private static final long serialVersionUID = 3701570113325116269L;
private String numero;
private String observacao;
@Enumerated(EnumType.STRING)
private StatusAcomodacao status = StatusAcomodacao.LIVRE;
private Integer nroDeQuartos;
private Integer capacidadeOcupacao;
private Integer capacidadeMaxima;
private Set<Caracteristica> caracteristicas = new HashSet<Caracteristica>(0);
@ManyToOne
private TipoAcomodacao tipoAcomodacao;
public String getNumero() {
return numero;
}
public String getObservacao() {
return observacao;
}
public StatusAcomodacao getStatus() {
return status;
}
public Integer getNroDeQuartos() {
return nroDeQuartos;
}
public Integer getCapacidadeOcupacao() {
return capacidadeOcupacao;
}
public Integer getCapacidadeMaxima() {
return capacidadeMaxima;
}
public void setNumero(String numero) {
this.numero = numero;
}
public void setObservacao(String observacao) {
this.observacao = observacao;
}
public void setStatus(StatusAcomodacao status) {
this.status = status;
}
public void setNroDeQuartos(Integer nroDeQuartos) {
this.nroDeQuartos = nroDeQuartos;
}
public void setCapacidadeOcupacao(Integer capacidadeOcupacao) {
this.capacidadeOcupacao = capacidadeOcupacao;
}
public void setCapacidadeMaxima(Integer capacidadeMaxima) {
this.capacidadeMaxima = capacidadeMaxima;
}
public TipoAcomodacao getTipoAcomodacao() {
return tipoAcomodacao;
}
public void setTipoAcomodacao(TipoAcomodacao tipoAcomodacao) {
this.tipoAcomodacao = tipoAcomodacao;
}
public void setCaracteristicas(Set<Caracteristica> caracteristicas) {
this.caracteristicas = caracteristicas;
}
@ManyToMany(cascade = CascadeType.ALL)
@JoinTable(name = "ACOMODACAO_CARACTERISTICA", joinColumns = { @JoinColumn(name = "ID") },
inverseJoinColumns = { @JoinColumn(name = "ID") })
public Set<Caracteristica> getCaracteristicas() {
return caracteristicas;
}
}
import javax.persistence.Entity;
import org.hibernate.validator.constraints.NotEmpty;
@Entity
public class Caracteristica extends BaseEntity {
private static final long serialVersionUID = 6760096265612712150L;
@NotEmpty
private String tipo;
private String observacoes;
public String getTipo() {
return tipo;
}
public String getObservacoes() {
return observacoes;
}
public void setTipo(String tipo) {
this.tipo = tipo;
}
public void setObservacoes(String observacoes) {
this.observacoes = observacoes;
}
}
@MappedSuperclass
public abstract class BaseEntity implements Serializable{
private static final long serialVersionUID = -1975247538988769496L;
@Id @GeneratedValue
private Long id;
