可以使用ActiveMQ提供的Compression设置来压缩和解压缩STOMP消息的内容。具体实现可以参考以下示例：

生产者发送压缩后的消息：

byte[] data = "Hello, world!".getBytes();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
GZIPOutputStream gzip = new GZIPOutputStream(baos);
gzip.write(data);
gzip.close();

byte[] compressedData = baos.toByteArray();

ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
Connection connection = connectionFactory.createConnection();
connection.start();

Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

Destination destination = session.createQueue("test.queue");
MessageProducer producer = session.createProducer(destination);

BytesMessage message = session.createBytesMessage();
message.writeBytes(compressedData);

producer.send(message);

session.close();
connection.close();

消费者接收并解压消息：

ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
Connection connection = connectionFactory.createConnection();
connection.start();

Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

Destination destination = session.createQueue("test.queue");
MessageConsumer consumer = session.createConsumer(destination);

Message message = consumer.receive();
if (message instanceof BytesMessage) {
    BytesMessage bytesMessage = (BytesMessage) message;
    byte[] compressedData = new byte[(int) bytesMessage.getBodyLength()];
    bytesMessage.readBytes(compressedData);

    ByteArrayInputStream bais = new ByteArrayInputStream(compressedData);
    GZIPInputStream gzip = new GZIPInputStream(bais);

    byte[] data = new byte[1024];
    int readBytes;
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    while ((readBytes = gzip.read(data)) != -1) {
        baos.write(data, 0, readBytes);
    }
    gzip.close();

    System.out.println(new String(baos.toByteArray(), StandardCharsets.UTF_8));
}

session.close();
connection.close();
