假设您的数据库有一个包含三列的person表,first_name,last_name,email_address.

然后你会写一个Person类：

import javafx.beans.property.StringProperty ;
import javafx.beans.property.SimpleStringProperty ;

public class Person {
    private final StringProperty firstName = new SimpleStringProperty(this,"firstName");
    public StringProperty firstNameProperty() {
        return firstName ;
    }
    public final String getFirstName() {
        return firstNameProperty().get();
    }
    public final void setFirstName(String firstName) {
        firstNameProperty().set(firstName);
    }

    private final StringProperty lastName = new SimpleStringProperty(this,"lastName");
    public StringProperty lastNameProperty() {
        return lastName ;
    }
    public final String getLastName() {
        return lastNameProperty().get();
    }
    public final void setLastName(String lastName) {
        lastNameProperty().set(lastName);
    }

    private final StringProperty email = new SimpleStringProperty(this,"email");
    public StringProperty emailProperty() {
        return email ;
    }
    public final String getEmail() {
        return emailProperty().get();
    }
    public final void setEmail(String email) {
        emailProperty().set(email);
    }

    public Person() {}

    public Person(String firstName,String lastName,String email) {
        setFirstName(firstName);
        setLastName(lastName);
        setEmail(email);
    }

}

从数据库访问数据的类：

import java.sql.Connection ;
import java.sql.DriverManager ;
import java.sql.SQLException ;
import java.sql.Statement ;
import java.sql.ResultSet ;

import java.util.List ;
import java.util.ArrayList ;

public class PersonDataAccessor {

    // in real life,use a connection pool....
    private Connection connection ;

    public PersonDataAccessor(String driverClassName,String dbURL,String user,String password) throws SQLException,ClassNotFoundException {
        Class.forName(driverClassName);
        connection = DriverManager.getConnection(dbURL,user,password);
    }

    public void shutdown() throws SQLException {
        if (connection != null) {
            connection.close();
        }
    }

    public List<Person> getPersonList() throws SQLException {
        try (
            Statement stmnt = connection.createStatement();
            ResultSet rs = stmnt.executeQuery("select * from person");
        ){
            List<Person> personList = new ArrayList<>();
            while (rs.next()) {
                String firstName = rs.getString("first_name");
                String lastName = rs.getString("last_name");
                String email = rs.getString("email_address");
                Person person = new Person(firstName,lastName,email);
                personList.add(person);
            }
            return personList ;
        } 
    }

    // other methods,eg. addPerson(...) etc
}

然后是UI类：

import javafx.application.Application ;
import javafx.scene.control.TableView ;
import javafx.scene.control.TableColumn ;
import javafx.scene.control.cell.PropertyValueFactory ;
import javafx.scene.layout.BorderPane ;
import javafx.scene.Scene ;
import javafx.stage.Stage ;

public class PersonTableApp extends Application {
    private PersonDataAccessor dataAccessor ;

    @Override
    public void start(Stage primaryStage) throws Exception {
        dataAccessor = new PersonDataAccessor(...); // provide driverName,dbURL,password...

        TableView<Person> personTable = new TableView<>();
        TableColumn<Person,String> firstNameCol = new TableColumn<>("First Name");
        firstNameCol.setCellValueFactory(new PropertyValueFactory<>("firstName"));
        TableColumn<Person,String> lastNameCol = new TableColumn<>("Last Name");
        lastNameCol.setCellValueFactory(new PropertyValueFactory<>("lastName"));
        TableColumn<Person,String> emailCol = new TableColumn<>("Email");
        emailCol.setCellValueFactory(new PropertyValueFactory<>("email"));

        personTable.getColumns().addAll(firstNameCol,lastNameCol,emailCol);

        personTable.getItems().addAll(dataAccessor.getPersonList());

        BorderPane root = new BorderPane();
        root.setCenter(personTable);
        Scene scene = new Scene(root,600,400);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    @Override
    public void stop() throws Exception {
        if (dataAccessor != null) {
            dataAccessor.shutdown();
        }
    }

    public static void main(String[] args) {
        launch(args);
    }
}
