java - RabbitMQ，主题交流

我的RabbitMQ上有一个主题交流。
发送消息时出错。

EXCHANGE_NAME = "EX_TEST";

接收部分：

ConnectionFactory connectionFactory = new ConnectionFactory();
connectionFactory.setHost(mServer);
mConnection = connectionFactory.newConnection();
mModel = mConnection.createChannel();
mModel.exchangeDeclare(EXCHANGE_NAME, MyExchangeType, true);
mQueue = mModel.queueDeclare().getQueue();
MySubscription = new QueueingConsumer(mModel);
mModel.queueBind(mQueue, EXCHANGE_NAME, routingKey);
mModel.basicConsume(mQueue, true, MySubscription);

发送部分：

ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare(EXCHANGE_NAME, "topic");

在线错误：channel.exchangeDeclare(EXCHANGE_NAME, "topic");
例外情况：
无法使用不同类型，持久性，内部或自动删除值，类ID = 40，方法ID = 10的虚拟主机'/'重新声明交换'EX_TEST'

如何解决呢？
谢谢：D

最佳答案

方法中的参数

mModel.exchangeDeclare(EXCHANGE_NAME, MyExchangeType, true);

和

channel.exchangeDeclare(EXCHANGE_NAME, "topic");

应该是相同的。
