如何解决TableView列中未显示日期数据
我正在用JavaFX制作一个小项目，该项目将人员及其各自的食品订单添加到列表中，到目前为止，除了上述列表中的“ fecha”列外，它的工作都令人惊奇。应该可以接收到接受订单后的当前本地日期和时间，但不能接受。
这是主要班级：
public class App extends Application {
private static Scene scene;
private static Stage stageAux; // Copia auxiliar de Stage,para uso en métodos menores
@Override
public void start(Stage stage) throws IOException {
stageAux = stage;
scene = new Scene(loadFXML("primary"),1200,720);
stage.setScene(scene);
stage.setTitle("Comandas Desayuno");
stage.show();
}
static void setRoot(String fxml) throws IOException {
scene.setRoot(loadFXML(fxml));
}
private static Parent loadFXML(String fxml) throws IOException {
FXMLLoader fxmlLoader = new FXMLLoader(App.class.getResource(fxml + ".fxml"));
return fxmlLoader.load();
}
public static void main(String[] args) {
launch();
}
public boolean fullscreen(){
stageAux.setFullScreen(!stageAux.isFullScreen());
return stageAux.isFullScreen();
}
}
这是主控制器：
public class PrimaryController implements Initializable {
private Connection con;
private Statement stat;
private ObservableList<Pedidos> pedidosList;
private Pedidos pedidoSeleccionado;
private Integer seleccion;
private int id = 1; // Contador de id de cada cliente
// SimpleDateFormat y Date para coger la hora a la que se ha hecho el pedido
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
Date currentDate = new Date();
private App app = new App();
private Functions f1 = new Functions();

private void clearElement(){

bebidaBox.getSelectionModel().select("Nada");
comidaBox.getSelectionModel().select("Nada");

}
private void editData(){
elementoLabel.setText("Editar Elemento");
f1.resetPrecioPedido();
f1.setBebida(bebidaBox.getValue());
f1.setComida(comidaBox.getValue());
pedidoSeleccionado = new Pedidos(
pedidoSeleccionado.getId(),bebidaBox.getValue(),comidaBox.getValue(),clientName.getText(),f1.getPrecioPedido(),currentDate,entregadoCheck.isSelected()
);
pedidosList.set(seleccion,pedidoSeleccionado);
tablaId.refresh(); // Actualiza la tabla automáticamente
tablaId.getSelectionModel().select(null); // Deselecciona la fila que se acaba de editar
elementoLabel.setText("Nuevo Elemento");
}
// Guarda los pedidos nuevos / Actualiza los pedidos seleccionados(con editData())
@FXML
private void save(ActionEvent event) {
f1.setBebida(bebidaBox.getValue());
f1.setComida(comidaBox.getValue());
Pedidos p = new Pedidos(
id,entregadoCheck.isSelected()
);
if(pedidoSeleccionado == null){
if(!pedidosList.contains(p)){
pedidosList.add(p);
id++;
}
} else {
editData();
}
f1.resetPrecioPedido();
clearElement();
}
// Pone en pantalla los datos editables del pedido seleccionado
@FXML
private void seleccionar(MouseEvent event) {
pedidoSeleccionado = tablaId.getSelectionModel().getSelectedItem();

clientName.setText(pedidoSeleccionado.getCliente());
bebidaBox.getSelectionModel().select(pedidoSeleccionado.getBebida());
comidaBox.getSelectionModel().select(pedidoSeleccionado.getComida());
entregadoCheck.setSelected(pedidoSeleccionado.getEntregado());
}
@FXML
private void delete(ActionEvent event) {
Pedidos p = tablaId.getSelectionModel().getSelectedItem();
pedidosList.remove(p);
}
@FXML
private void close(ActionEvent event) {
System.exit(0);
}
@FXML
private void goFullscreen(ActionEvent event) {
app.fullscreen();
}
@Override
public void initialize(URL url,ResourceBundle rb){
pedidosList = FXCollections.observableArrayList();
tablaId.setItems(pedidosList);
idColumn.setCellValueFactory(new PropertyValueFactory("id"));
clienteColumn.setCellValueFactory(new PropertyValueFactory("cliente"));

// Lista completa de bebidas
bebidaBox.getItems().addAll(
"Nada","Café Solo - 0.8€","Café con Leche - 1€","Refresco - 1.5€","Colacao - 1.5€");
bebidaBox.getSelectionModel().select("Nada");
// Lista completa de comidas
comidaBox.getItems().addAll(
"Nada","Pitufo Mixto - 1.5€","Pitufo Bacon - 1.7€","Pitufo Lomo - 2€","Bocata Paté - 2.5€","Bocata Bacon - 3€","Bocata Chorizo - 3.5€");
comidaBox.getSelectionModel().select("Nada");
}
}
这是“ Pedidos”类：
public class Pedidos {
private int id;
private String bebida;
private String comida;
private String cliente;
private double precio;
private Date currentDate;
private Boolean entregado;
public Pedidos() {
}
public Pedidos(int id,String bebida,String comida,String cliente,double precio,Date currentDate,boolean entregado) {
this.id = id;
this.bebida = bebida;
this.comida = comida;
this.cliente = cliente;
this.precio = precio;
this.currentDate = currentDate;
this.entregado = entregado;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getBebida() {
return bebida;
}
public void setBebida(String bebida) {
this.bebida = bebida;
}
public String getComida() {
return comida;
}
public void setComida(String comida) {
this.comida = comida;
}
public String getCliente() {
return cliente;
}
public void setCliente(String cliente) {
this.cliente = cliente;
}
public double getPrecio() {
return precio;
}
public void setPrecio(double precio) {
this.precio = precio;
}
public Date getCurrentDate() {
return currentDate;
}
public void setCurrentDate(Date currentDate) {
this.currentDate = currentDate;
}
public Boolean getEntregado() {
return entregado;
}
public void setEntregado(Boolean entregado) {
this.entregado = entregado;
}
@Override
public int hashCode() {
int hash = 7;
return hash;
}
@Override
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final Pedidos other = (Pedidos) obj;
if (this.id != other.id) {
return false;
}
if (Double.doubleToLongBits(this.precio) != Double.doubleToLongBits(other.precio)) {
return false;
}
if (!Objects.equals(this.bebida,other.bebida)) {
return false;
}
if (!Objects.equals(this.comida,other.comida)) {
return false;
}
if (!Objects.equals(this.cliente,other.cliente)) {
return false;
}
if (!Objects.equals(this.currentDate,other.currentDate)) {
return false;
}
if (!Objects.equals(this.entregado,other.entregado)) {
return false;
}
return true;
}
@Override
public String toString() {
return "Pedidos{" + "id=" + id + ",bebida=" + bebida + ",comida=" + comida + ",cliente=" + cliente + ",precio=" + precio + ",currentDate=" + currentDate + ",entregado=" + entregado + '}';
}
}
这是当我在列表中输入新人员时出现的终端输出：

这可能真的很愚蠢，但是我已经花了一段时间了，但我只是找不到如何使它起作用。
