Question

我正在尝试在加载时填充tableview。如果有任何错误，请原谅。

public class users {

    public String username;
    public String FullName;
    public String password;
    public String phone;
    public String email;
    public String doj;
    public String city;
    public String state;
    public String address;


    public ObservableList <ListEmply> emplylst = FXCollections.observableArrayList();

}

public class UserDetail {

    @FXML
    private ObservableList <ListEmply> emplylst;
    @FXML
    private TableView <ListEmply> tbl_employeeview;
    @FXML
    private TableColumn<Object, Object> employeename;

    users User = new users();


    Dbconnection dbcon = new Dbconnection();
    Connection con;
    PreparedStatement pst;
    ResultSet rs;



    public void showDetails(users User){
        con = dbcon.geConnection();
        try{
        pst = con.prepareStatement("select room_no from room");
        rs = pst.executeQuery();
        while (rs.next()){
        User.emplylst.add(new ListEmply(
                rs.getString(1)
                ));

                }
        System.out.println(rs);
            rs.close();
            pst.close();
            con.close();
        } catch (SQLException e) {
            e.printStackTrace();
            }
        }


    public void usrdetails(){
        tbl_employeeview.setItems(emplylst);
        showDetails(User);
        employeename.setCellValueFactory(new PropertyValueFactory<>("employeename"));
        System.out.println(rs);
    }


    public void Initializable(URL url, ResourceBundle rb){

        usrdetails();
    }   
}

ListEmply Class

public class ListEmply {

    public String employeename;
    public ListEmply(String employeename) {
        super();
        this.employeename = employeename;
    }
    public String getEmployeename() {
        return employeename;
    }
    }
    public void setEmployeename(String employeename) {
        this.employeename = employeename;
    }
}

如documentation中所述，调用初始化控制器的控制器方法称为initialize(...)，而不是Initializable(...)：

public void initialize(URL url, ResourceBundle rb){

    usrdetails();
}

正如@fabian在评论中所指出的那样，由于您没有实现（遗留）接口Initializable而不使用参数，您可以省略方法定义中的参数：

public void initialize(){

    usrdetails();
}

javafx tableview在初始化时无法获取数据
