由于某些原因,即使我在Spring AMQP Queue配置中指定了该设置,我的队列也不会创建为持久性:
@Bean
Queue queue() {
//durable queue - true
return new Queue(queueName, true);
}
我使用Spring AMQP连接到RabbitMQ并在Direct Exchange上侦听该队列。
@Bean
DirectExchange exchange() {
return new DirectExchange(exchangeName);
}
@Bean
Binding binding(Queue queue, DirectExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(queueName);
}
@Bean
public ConnectionFactory connectionFactory() {
CloudFactory cloudFactory = new CloudFactory();
Cloud cloud = cloudFactory.getCloud();
AmqpServiceInfo serviceInfo = (AmqpServiceInfo)
cloud.getServiceInfo(serviceName);
CachingConnectionFactory connectionFactory =
new CachingConnectionFactory(serviceInfo.getHost());
connectionFactory.setUsername(serviceInfo.getUserName());
connectionFactory.setPassword(serviceInfo.getPassword());
connectionFactory.setVirtualHost(serviceInfo.getVirtualHost());
return connectionFactory;
}
@Bean
MessageListenerAdapter underwritingMessageListener() throws Exception {
return new MessageListenerAdapter(new UnderwritingMessageListener()) {{
setDefaultListenerMethod("onMessage");
}};
}
@Bean
SimpleMessageListenerContainer container(ConnectionFactory connectionFactory,
MessageListenerAdapter underwritingMessageListener) {
SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
container.setConnectionFactory(connectionFactory);
container.setQueueNames(queueName);
container.setMessageListener(underwritingMessageListener);
return container;
}
我错过了配置步骤吗?

该设置未生效,因为在部署上述代码之前,Queue已经存在,非持久性。通过管理控制台或CLI删除队列,允许应用程序将队列声明为持久(重启后)。
如果在已经在不同状态下声明Queue而不是继续进行无效部署时,Spring-AMQP(RabbitMQ)引发异常会很有帮助。

您需要RabbitAdmin
@Bean
来进行声明。
它将自己注册到连接工厂,并在建立连接时执行声明。
