How to Connect JavaFX to a MySQL Database and Display Data in a TableView?

JavaFX, MySQL Connection Example

In JavaFX, establishing a connection to a MySQL database and retrieving data is a common task. This article provides a straightforward example of how to accomplish this, focusing on the fundamental aspects of the process.

To illustrate the concept, consider a simple MySQL table named "person" with three columns: "first_name," "last_name," and "email_address."

1. Data Representation:

We begin by defining a class, Person, to represent the data from the database:

public class Person {
    // ...
}

2. Database Connection Management:

Next, we create a class, PersonDataAccessor, responsible for managing the database connection and executing queries:

public class PersonDataAccessor {
    // ...
}

3. UI Integration:

Finally, we use a class like PersonTableApp to integrate the database functionality into our JavaFX application, displaying the results in a TableView:

public class PersonTableApp extends Application {
    // ...
}

Code Sample:

The following code sample elaborates on this approach, providing concrete implementation details:

Person Class:

public class Person {
    private final StringProperty firstName = new SimpleStringProperty(this, "firstName");
    // ...
}

PersonDataAccessor Class:

public class PersonDataAccessor {
    public List<Person> getPersonList() throws SQLException {
        // ...
}

PersonTableApp Class:

public class PersonTableApp extends Application {
    // ...
    @Override
    public void start(Stage primaryStage) throws Exception {
        // ...
    }
    // ...
}

By following these steps, you can establish a connection between your JavaFX application and a MySQL database, retrieve data, and integrate it into your UI.
