JavaFX Table view using MySQL database 'No content in table' - mysql

Question

I am new to JavaFX. I develop an JavaFX application. I want to show data from MySQL database in TableView.
When I add data from JavaFX, data is perfectly stored in database, but it shows 'No content in table' in tableview. There is no error in my code, I could not find where I made the mistake. I am using Eclipse IDE.
This is Customer class:
package application;
import javafx.beans.property.IntegerProperty;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Customer {
private final StringProperty pname;
private final IntegerProperty pphno;
private final StringProperty paddress;
public Customer(String pname,int pphno,String paddress){
this.pname = new SimpleStringProperty(pname);
this.pphno = new SimpleIntegerProperty(pphno);
this.paddress = new SimpleStringProperty(paddress);
}
public StringProperty getpname() {
return pname;
}
public IntegerProperty getpphno() {
return pphno;
}
public StringProperty getpaddress() {
return paddress;
}
}
This is Cust.fxml:

This is CustController class:
package application;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.TextField;
public class CustController implements Initializable {
#FXML
private TableView<Customer> tbl_cust;
#FXML
private TableColumn<Customer, String> tcol_name;
#FXML
private TableColumn<Customer, Integer> tcol_phno;
#FXML
private TableColumn<Customer, String> tcol_add;
#FXML
private TextField txt_name;
#FXML
private TextField txt_phno;
#FXML
private TextField txt_add;
#FXML
private Button btn_save;
#FXML
private Button btn_update;
#FXML
private Button btn_del;
private String query, cname, cphno, cadd;
DataAccessObj dao;
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
dao = new DataAccessObj();
btn_save.setOnAction(e->{
insertNewCustomer();
});
refreshTable();
}
private void initTable() {
tcol_name.setCellValueFactory(cell->cell.getValue().getpname());
tcol_phno.setCellValueFactory(cell->cell.getValue().getpphno().asObject());
tcol_add.setCellValueFactory(cell->cell.getValue().getpaddress());
}
private void refreshTable() {
initTable();
query = "select a.Name, a.Phno, a.Address from customer ordered by a.Name";
tbl_cust.setItems(dao.getCustomerData(query));
}
private void insertNewCustomer() {
cname = txt_name.getText();
cphno = txt_phno.getText();
cadd = txt_add.getText();
query = "insert into customer values('"+cname+"', '"+cphno+"', '"+cadd+"');";
dao.savedata(query);
txt_name.setText("");
txt_phno.setText("");
txt_add.setText("");
refreshTable();
}
}
This is DataAccessObject class:
package application;
import java.sql.Connection;
import java.sql.PreparedStatement;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import java.sql.ResultSet;
public class DataAccessObj {
private DBConnection database = new DBConnection();
private ResultSet rs;
private PreparedStatement ps;
private Connection connect;
public DataAccessObj() {
}
public void savedata(String query) {
try {
connect = database.getConnection();
ps = connect.prepareStatement(query);
ps.executeUpdate();
}catch(Exception e) {
e.printStackTrace();
}finally {
database.close(connect, ps, null);
}
}
public ObservableList<Customer> getCustomerData(String query){
ObservableList list = FXCollections.observableArrayList();
try {
connect = database.getConnection();
ps = connect.prepareStatement(query);
rs = ps.executeQuery();
while(rs.next()) {
list.add(new Customer(rs.getString(1), rs.getInt(2), rs.getString(3)));
}
}catch(Exception e) {
e.printStackTrace();
}
return list;
}
}
I am trying to get customer details from database. Database is connected to the javafx and it stores data from javafx but doesn't show data in javafx tableview.
