我已經(jīng)為 rabbit mq 設(shè)置了一個(gè)簡(jiǎn)單的監(jiān)聽器@RabbitListener(queues = SECOND_QUEUE)    public void onMessage(Message message) {     LOGGER.info("second queue listener.........");     LOGGER.info(message.toString());    }這給出了這種格式的消息 (Body:'1460' MessageProperties [headers={}, timestamp=null, messageId=null, userId=null, receivedUserId=null, appId=null, clusterId=null, type=null, correlationId=null, correlationIdString=null, replyTo=null, contentType=application/x-java-serialized-object, contentEncoding=null, contentLength=0, deliveryMode=null, receivedDeliveryMode=PERSISTENT, expiration=null, priority=0, redelivered=false, receivedExchange=, receivedRoutingKey=bottomlesspit, receivedDelay=null, deliveryTag=1, messageCount=0, consumerTag=amq.ctag-PpEjG_BokAg-A4wllCgeqA, consumerQueue=bottomlesspit])在控制臺(tái)上。我也有興趣在客戶端處理消息，我有這個(gè)var onConnect = function() {   client.subscribe("/topic/messages", function(d) {   var str = d.body   var res = str.match(/Body:\'(.+)\'/);   console.log("I control this",res[1]);   }); };我只想在 java 中獲取主體，因?yàn)樗俏夷壳拔ㄒ桓信d趣的部分。是否有一個(gè)功能已經(jīng)在 java 和 stomp 中實(shí)現(xiàn)，僅用于獲取正文部分？。
