我想将ad对象类型传递给messageheaders，并在stompframehandler中使用它。有时我发送myobject1，有时发送myobject2。我希望处理程序使用头信息转换它。

Message<HeartBeat> msg = MessageBuilder.withPayload(payload)
                .setHeader("payloadType", MyObject1.class)
                .build();

@Component
@RequiredArgsConstructor
public class MyObject2Handler implements StompFrameHandler {

    @SneakyThrows
    @Override
    public Type getPayloadType(StompHeaders stompHeaders) {
        return stompHeaders.get("payloadType").get(0) ... ???
    }

    @Override
    public void handleFrame(StompHeaders stompHeaders, Object o) {
        log.info(" <<< in <<< [{}] with headers: [{}]", o, stompHeaders);
    }
}
