JavaFX.TableView의 날짜 형식

Question

문제가 발생했습니다. 채우기 위해

public class PatientEntity { 

    private int id; 
    private Date dateDoc; 
    private String secondname; 
    private String firstname; 
    private String thirdname; 

    @Id 
    @Column(name = "ID") 
    public int getId() { 
     return id; 
    } 

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

    @Basic 
    @Column(name = "Date_doc") 
    public Date getDateDoc() { 
     return dateDoc; 
    } 

    public void setDateDoc(Date dateDoc) { 
     this.dateDoc = dateDoc; 
    } 

나는 그런 식으로 JavaFX.TableView을 사용하고 있습니다 : 결과에서

columnID.setCellValueFactory(new PropertyValueFactory<PatientEntity, Integer>("id")); 
columnDate.setCellValueFactory(new PropertyValueFactory<PatientEntity, Date>("dateDoc")); 
columnSecondname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("secondname")); 
columnFirstname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("firstname")); 
columnThirdname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("thirdname")); 

tableView.setItems(FXCollections.observableList(patients)); 

:

은 내가 POJO 클래스가 the result of running

그것은 잘 작동하지만 TableView에 dd.mm.yyyy와 같은 Date의 다른 형식이 필요합니다. 그러면 내가 어떻게 할 수 있니? 보시다시피, TableView에는 간단한 문자열이 아닌 객체가 포함되어 있습니다.

private synchronized void updateTableView(List <PatientEntity> patients){ 

    columnID.setCellValueFactory(new PropertyValueFactory<PatientEntity, Integer>("id")); 
    columnDate.setCellFactory(column -> { 
     TableCell<PatientEntity, Date> cell = new TableCell<PatientEntity, Date>() { 
      private SimpleDateFormat format = new SimpleDateFormat("dd.MM.yyyy"); 

      @Override 
      protected void updateItem(Date item, boolean empty) { 
       super.updateItem(item, empty); 
       if(empty) { 
        setText(null); 
       } 
       else { 
        this.setText(format.format(item)); 

       } 
      } 
     }; 

     return cell; 
    }); 

    columnSecondname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("secondname")); 
    columnFirstname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("firstname")); 
    columnThirdname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("thirdname")); 
    tableView.setItems(FXCollections.observableList(patients)); 
} 

Such result

해결

@mr mcwolf에게 감사의 말을 전합니다!

우리는 두 가지 방법이 필요합니다 첫 번째 방법은 우리가 초기화하는 동안 한 번 호출 구성 방법입니다 :

private void configureTableView(){ 
    columnID.setCellValueFactory(new PropertyValueFactory<PatientEntity, Integer>("id")); 
    columnDate.setCellFactory(column -> { 
     TableCell<PatientEntity, Date> cell = new TableCell<PatientEntity, Date>() { 
      private SimpleDateFormat format = new SimpleDateFormat("dd.MM.yyyy"); 

      @Override 
      protected void updateItem(Date item, boolean empty) { 
       super.updateItem(item, empty); 
       if(empty) { 
        setText(null); 
       } 
       else { 
        this.setText(format.format(item)); 

       } 
      } 
     }; 

     return cell; 
    }); 
    columnDate.setCellValueFactory(new PropertyValueFactory<PatientEntity, Date>("dateDoc")); 
    columnSecondname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("secondname")); 
    columnFirstname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("firstname")); 
    columnThirdname.setCellValueFactory(new PropertyValueFactory<PatientEntity, String>("thirdname")); 

} 

그리고 우리가있는 tableView을 채우기 위해하는 방법이 필요합니다

private synchronized void fillTableView(List <PatientEntity> patientsList){ 

    Thread threadConnectingToDB = new Thread(() -> { 
     try { 
      List<PatientEntity> patients = patientsList; 
      if(patients == null) { 
       PatientDAO patientDAO = FactoryDAO.getInstance().getPatientDAO(); 
       if (patientDAO.getAllPatients() instanceof List) { 
        patients = (List) patientDAO.getAllPatients(); 
       } else { 
        patients = new ArrayList(patientDAO.getAllPatients()); 
       } 
      } 
      tableView.setItems(FXCollections.observableList(patients)); 
     } catch (SQLException e) { 
      try { 
       ErrorStage.display("Error Connection"); 
      } catch (Exception e1) { 
       e1.printStackTrace(); 
      } 
      e.printStackTrace(); 
     } 
    }); 
    threadConnectingToDB.start(); 
    threadConnectingToDB.interrupt(); 
}

이

columnDate.setCellFactory(column -> { 
    TableCell<PatientEntity, Date> cell = new TableCell<PatientEntity, Date>() { 
     private SimpleDateFormat format = new SimpleDateFormat("dd.MM.yyyy"); 

     @Override 
     protected void updateItem(Date item, boolean empty) { 
      super.updateItem(item, empty); 
      if(empty) { 
       setText(null); 
      } 
      else { 
       setText(format.format(item)); 
      } 
     } 
    }; 

    return cell; 
});
