推荐答案

遇到了同样的问题.必须使用以下命令实现自定义 WebSocketHandlerDecorator:

Got the same issue. Had to implement a custom WebSocketHandlerDecorator with:

public void handleMessage(final WebSocketSession session, final WebSocketMessage<?> message) throws Exception {
    if (message instanceof TextMessage) {
        TextMessage msg = (TextMessage) message;
        String payload = msg.getPayload();
        // only add \00 if not present (iOS / Android)
        if (!payload.substring(payload.length() - 1).equals("\u0000")) {
            super.handleMessage(session, new TextMessage(payload + "\u0000"));
            return;
        }
    }

    super.handleMessage(session, message);
}
