以下是一个示例代码，演示如何在Jython中使用OpenWire库连接ActiveMQ，将一个主题（topic）上的订阅消息转发到另一个ActiveMQ服务器上：

from org.apache.activemq import *
from org.apache.activemq.transport import *# 创建连接工厂
factory = ConnectionFactory()
factory.setBrokerURL("tcp://localhost:61616")# 创建连接
connection = factory.createConnection()
connection.start()# 创建生产者
producer = connection.createProducer(ActiveMQDestination("MY_QUEUE"))# 创建消息转换器，将BytesMessage转换为String
transformer = Transformers.transformers().addTransformer(BytesMessageToStringTransformer())# 创建目标连接工厂和连接
targetFactory = ConnectionFactory()
targetFactory.setBrokerURL("tcp://target_server:61616")
targetConnection = targetFactory.createConnection()
targetConnection.start()
targetDestination = ActiveMQDestination("TARGET_TOPIC")
targetProducer = targetConnection.createProducer(targetDestination)# 订阅主题并转发消息
consumer = connection.createConsumer(ActiveMQDestination("MY_TOPIC"))
consumer.setMessageListener(new MessageListener() {public void onMessage(Message message) {try {# 将接收到的BytesMessage转换为Stringtransformer.transform(message);String messageText = message.toString();System.out.println("Received message: " + messageText);# 创建新的消息并发送到目标服务器Message newMessage = connection.createMessage();newMessage.setStringProperty("text", messageText);targetProducer.send(newMessage)} catch (JMSException e) {e.printStackTrace();}}
});

请注意，上述代码中的MY_QUEUE、MY_TOPIC、TARGET_TOPIC和target_server需要替换为你自己的实际值。此外，你可能需要根据你的具体需求进行适当的调整和错误处理。
