【中文标题】RabbitTemplate 连接到 RabbitMQ:获取 - NOT_FOUND - 无队列【英文标题】:RabbitTemplate to connect to RabbitMQ : getting - NOT_FOUND - no queue 【发布时间】:2017-01-20 15:57:25 【问题描述】:我是 Spring 新手,正在开发基于云的应用程序并尝试使用 RabbitTemplate 和 RabbitMQ。
我能够将数据存储到队列中。
rabbitTemplate.convertAndSend(QUEUE_NAME, msg);
但是当我使用从同一个队列接收数据时
rabbitTemplate.receiveAndConvert(QUEUE_NAME)
我遇到了异常:

我的代码:
@Configuration
@Profile("cloud")
public class RabbitConfig extends AbstractCloudConfig
@Bean
public RabbitTemplate rabbitTemplate()
CachingConnectionFactory cachingConnectionFactory = (CachingConnectionFactory)connectionFactory().rabbitConnectionFactory();
cachingConnectionFactory.setCacheMode(CachingConnectionFactory.CacheMode.CHANNEL);
RabbitTemplate rabbitTemplate = new RabbitTemplate(cachingConnectionFactory);
return rabbitTemplate;
我的控制器:
@RestController
@RequestMapping("mq")
public class MainController
@Autowired
private RabbitTemplate rabbitTemplate;
private static final String QUEUE_NAME = "testqueue";
@RequestMapping(value = "/putinq/msg",method = RequestMethod.PUT)
public String storeMessage(@PathVariable("msg") String msg)
String result = "";
rabbitTemplate.setQueue(QUEUE_NAME);
try
rabbitTemplate.convertAndSend(QUEUE_NAME, msg); // no exception
Thread.sleep(3000);
Object object = rabbitTemplate.receiveAndConvert(QUEUE_NAME); // getting exception here
System.out.println("Received: "+object);
result = "success";
catch(Exception ex)
ex.printStackTrace();
return result;
更新的 RabbitConfig.java
@Configuration
@Profile("cloud")
public class RabbitConfig extends AbstractCloudConfig
private static final String QUEUE_NAME = "testqueue";
@Bean
public RabbitTemplate rabbitTemplate()
CachingConnectionFactory cachingConnectionFactory = (CachingConnectionFactory)(connectionFactory().rabbitConnectionFactory());
System.out.println("------------------------ Rabbit mq template: " + cachingConnectionFactory.getCacheMode());
System.out.println("------------------------ cachingConnectionFactory.toString(): " + cachingConnectionFactory.toString());
cachingConnectionFactory.setCacheMode(CachingConnectionFactory.CacheMode.CHANNEL);
cachingConnectionFactory.setChannelCacheSize(25);
System.out.println("----------after set-------------- Rabbit mq template: " + cachingConnectionFactory.getCacheMode());
System.out.println("------------------------ cachingConnectionFactory.toString(): " + cachingConnectionFactory.getChannelCacheSize());
RabbitTemplate rabbitTemplate = new RabbitTemplate(cachingConnectionFactory);
System.out.println("------------------------ Rabbit mq template: " + rabbitTemplate);
return rabbitTemplate;
@Bean
public Queue myQueue()
System.out.println("--------------@@---------- creating queue: ");
final boolean isDurable = true;
final boolean isExclusive = false;
final boolean autoDelete = false;
return new Queue(QUEUE_NAME, isDurable, isExclusive, autoDelete);
我尝试在互联网上搜索此问题,但仍然无法解决问题,长期与此异常作斗争,感谢任何帮助。
找到解决方案!
CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
cachingConnectionFactory.setUsername("");
cachingConnectionFactory.setPassword("");
cachingConnectionFactory.setVirtualHost("");
cachingConnectionFactory.setHost("");
cachingConnectionFactory.setPort(1);
cachingConnectionFactory.setRequestedHeartBeat(30);
cachingConnectionFactory.setConnectionTimeout(30000);
RabbitAdmin admin = new RabbitAdmin(cachingConnectionFactory());
Queue queue = new Queue(QUEUE_NAME);
admin.declareQueue(queue);
TopicExchange exchange = new TopicExchange(EXCHANGE_NAME);
admin.declareExchange(exchange); admin.declareBinding(BindingBuilder.bind(queue).to(exchange).with(QUEUE_NAME));
RabbitTemplate template = new RabbitTemplate(cachingConnectionFactory());
【问题讨论】:
【参考方案1】:您需要 RabbitAdmin
@Bean
来声明队列/绑定 - 它会自动查找这些类型的 bean 并在建立连接时在代理上声明它们。
如果你使用 Spring Boot,它会自动为你注册一个模板和管理员。
【讨论】:
【参考方案2】:你需要绑定你的队列和exchage,请试试下面这个RabbitmqConfig
@Configuration
public class RabbitmqConfig
private static final String QUEUE_NAME = "testqueue";
@Bean
Queue queue()
return new Queue(QUEUE_NAME, false);
@Bean
TopicExchange exchange()
return new TopicExchange("spring-boot-exchange", true, false);
@Bean
Binding binding(Queue queue, TopicExchange exchange)
return BindingBuilder.bind(queue).to(exchange).with(QUEUE_NAME);
【讨论】:
得到同样的错误:ERR 原因:com.rabbitmq.client.ShutdownSignalException:通道错误;协议方法:#methodrabbitTemplate.setQueue(QUEUE_NAME);
。
雅丽萍,做到了,不走运!我不知道为什么它仍然给出这个错误。
@RiteshKaushik 你能去 rabbitmq 管理员检查队列/频道吗?【参考方案3】:
您需要在配置中定义队列本身。
@Bean
public org.springframework.amqp.core.Queue myQueue()
final boolean isDurable = true;
final boolean isExclusive = false;
final boolean autoDelete = false;
return new org.springframework.amqp.core.Queue(QUEUE_NAME, isDurable, isExclusive, autoDelete);
【讨论】:
嗨,杰夫,感谢您的回复,我仍然收到同样的错误:原因:com.rabbitmq.client.ShutdownSignalException:通道错误;协议方法:#methodBinding
你的Queue
和Exchange
了吗?
删除rabbitTemplate()方法会怎样?以上是关于RabbitTemplate 连接到 RabbitMQ:获取 - NOT_FOUND - 无队列的主要内容,如果未能解决你的问题,请参考以下文章
