JAVA使用JDBC連線SQLITE資料庫

SQLITE非常小巧實用,對於一般應用的資料處理需求可以很好滿足。
JAVA如何使用JDBC連線SQLITE資料庫呢?
首先,需要下載一個sqlite-jdbc的驅動類:
https://github.com/xerial/sqlite-jdbc
將此驅動類匯入應用的類庫中,然後就可以在應用中使用SQLITE資料庫做各種操作了:
package bingword; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.logging.Level; import java.util.logging.Logger; import javafx.application.Application; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.GridPane; import javafx.stage.Stage; public class BingWord extends Application { private final GridPane grid = new GridPane(); private final Button btn = new Button(); @Override public void start(Stage primaryStage) { btn.setText("Say 'Hello World'"); btn.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent event) { System.out.println("Hello World!"); sqliteTest(); } }); grid.add(btn, 0, 0); Scene scene = new Scene(grid, 300, 250); primaryStage.setTitle("Hello World!"); primaryStage.setScene(scene); primaryStage.show(); } public static void main(String[] args) { launch(args); } public void sqliteTest() { Connection connection = null; try { connection = DriverManager.getConnection("jdbc:sqlite:sample.db"); Statement statement = connection.createStatement(); statement.setQueryTimeout(30); statement.executeUpdate("drop table if exists dictionary"); statement.executeUpdate("create table dictionary (word string,p1 string,p2 string)"); statement.executeUpdate("insert into dictionary values('one','wan','WAN')"); statement.executeUpdate("insert into dictionary values('two','tu','TU')"); ResultSet rs = statement.executeQuery("select * from dictionary"); while (rs.next()) { System.out.println(rs.getString("word") + rs.getString("p1") + rs.getString("p2")); } } catch (SQLException ex) { Logger.getLogger(BingWord.class.getName()).log(Level.SEVERE, null, ex); } } }
