如何在Java中用okhttp实现scarlet库？

<!-- Maven -->
<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>版本号</version>
</dependency>

// Gradle
implementation 'com.squareup.okhttp3:okhttp:版本号'

OkHttpClient client = new OkHttpClient();

Request request = new Request.Builder()
        .url("WebSocket服务器URL")
        .build();

WebSocket webSocket = client.newWebSocket(request, new WebSocketListener() {
    @Override
    public void onOpen(WebSocket webSocket, Response response) {
        // WebSocket连接已打开
    }

    @Override
    public void onMessage(WebSocket webSocket, String text) {
        // 收到WebSocket服务器发送的消息
    }

    @Override
    public void onClosed(WebSocket webSocket, int code, String reason) {
        // WebSocket连接已关闭
    }

    @Override
    public void onFailure(WebSocket webSocket, Throwable t, Response response) {
        // WebSocket连接失败
    }
});

@WebSocket
interface MyWebSocket {
    @Receive
    void onMessage(String message);
}

Scarlet scarlet = new Scarlet.Builder()
        .webSocketFactory(client.newWebSocketFactory(request))
        .addMessageAdapterFactory(new GsonMessageAdapter.Factory())
        .build();

MyWebSocket myWebSocket = scarlet.create(MyWebSocket.class);
myWebSocket.onMessage("Hello, WebSocket!");
