mais o hibernate esta me retornando um erro que nao estou conseguindo interpretar, ou melhor, pelo erro parece que meus beans estao errados… mais eu os revisei e nao encontrei erro… segue os Beans e a consulta
Bean Menu
@Entity
@Table(name = "menu")
public class Menu implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "idmenu", nullable = false)
private Integer idmenu;
@Column(name = "nome")
private String nome;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "menuIdmenu")
private Collection<Permissoes> permissoesCollection;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "menuIdmenu")
private Collection<MenuItem> menuItemCollection;
public Menu() {
}
public Menu(Integer idmenu) {
this.idmenu = idmenu;
}
public Menu(String nome){
this.nome = nome;
}
public Integer getIdmenu() {
return idmenu;
}
public void setIdmenu(Integer idmenu) {
this.idmenu = idmenu;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}Bean MenuItem
@Entity
@Table(name = "menu_item")
public class MenuItem implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "idmenu_item", nullable = false)
private Integer idmenuItem;
@Column(name = "nome")
private String nome;
@JoinColumn(name = "menu_idmenu", referencedColumnName = "idmenu")
@ManyToOne
private Menu menuIdmenu;
public MenuItem() {
}
public MenuItem(String nome, Menu menu){
this.nome = nome;
this.menuIdmenu = menu;
}
public MenuItem(Menu menu){
this.menuIdmenu = menu;
}
public MenuItem(Integer idmenuItem) {
this.idmenuItem = idmenuItem;
}
public Integer getIdmenuItem() {
return idmenuItem;
}
public void setIdmenuItem(Integer idmenuItem) {
this.idmenuItem = idmenuItem;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public Menu getMenuIdmenu() {
return menuIdmenu;
}
public void setMenuIdmenu(Menu menuIdmenu) {
this.menuIdmenu = menuIdmenu;
}Consulta :
public static List buscarWhereObjeto(Class cls,String propriedade, Object obj){
return sessao.createCriteria(cls).add(Restrictions.eq(propriedade, obj)).list();
}
List<MenuItem> itens = DAO.buscarWhereObjeto(MenuItem.class, "menuIdmenu", new MenuItem(menu));
