您可以使用 BinaryWebSocketHandler 处理二进制消息通信。
完整的例子
@Configuration@EnableAutoConfiguration@EnableWebSocketpublic class AppWebSocket { public static void main(String[] args) { SpringApplication.run(AppWebSocket.class, args); } @Component public static class MyWebSocketConfigurer implements WebSocketConfigurer { @Override public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) { registry.addHandler(new MyTextHandler(), "/text").withSockJS(); registry.addHandler(new MyBinaryHandler(), "/binary").withSockJS(); } } @Component public static class MyTextHandler extends TextWebSocketHandler { public void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception { session.sendMessage(new TextMessage("hello world")); } } @Component public static class MyBinaryHandler extends BinaryWebSocketHandler { public void handleBinaryMessage(WebSocketSession session, BinaryMessage message) { try { session.sendMessage(new BinaryMessage("hello world".getBytes())); } catch (IOException e) { e.printStackTrace(); } } }}
