javafx websocket ssl

要在JavaFX中使用WebSocket并启用SSL加密，您可以使用Java API for WebSocket（JSR 356）和Java SSL API来实现。下面是一个简单的示例代码：

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManagerFactory;
import javax.websocket.ClientEndpoint;
import javax.websocket.ContainerProvider;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.WebSocketContainer;
import java.io.FileInputStream;
import java.net.URI;
import java.security.KeyStore;

@ClientEndpoint
public class JavaFXWebSocketSSLExample extends Application {
    private TextField inputField;
    private TextArea outputArea;
    private Session session;

    @Override
    public void start(Stage primaryStage) throws Exception {
        inputField = new TextField();
        outputArea = new TextArea();

        VBox root = new VBox(inputField, outputArea);
        Scene scene = new Scene(root, 800, 600);
        primaryStage.setScene(scene);
        primaryStage.show();

        // 创建WebSocket容器
        WebSocketContainer container = ContainerProvider.getWebSocketContainer();

        // 配置SSL上下文
        SSLContext sslContext = SSLContext.getInstance("TLS");
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(new FileInputStream("truststore.jks"), "password".toCharArray());
        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        trustManagerFactory.init(trustStore);
        sslContext.init(null, trustManagerFactory.getTrustManagers(), null);

        // 设置SSL上下文
        container.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

        // 连接到WebSocket服务器
        session = container.connectToServer(this, new URI("wss://your-websocket-server-url"));
    }

    @Override
    public void stop() throws Exception {
        // 关闭WebSocket连接
        session.close();
    }

    @OnOpen
    public void onOpen(Session session) {
        // 连接打开时的处理逻辑
    }

    @OnClose
    public void onClose(Session session) {
        // 连接关闭时的处理逻辑
    }

    @OnError
    public void onError(Session session, Throwable throwable) {
        // 错误发生时的处理逻辑
    }

    @OnMessage
    public void onMessage(String message) {
        // 收到消息时的处理逻辑
    }

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

请注意，您需要将代码中的 "wss://your-websocket-server-url" 替换为实际的WebSocket服务器URL，并在`SSLContext`初始化中提供适当的证书和密码。

这是一个简单的示例，仅用于演示如何在JavaFX中使用WebSocket和SSL。根据您的具体需求，可能需要进一步自定义和配置SSL上下文以满足安全要求。
