Spring-amqp RabbitMQ - 没有在'vhost'/'ERROR中交换'myexchange'

Question

我知道之前已经问过这个问题，但我找不到任何合适的解决方案来解决我的问题，因此再次发布。

我正在尝试使用spring-amqp编写一个rabbitmq生成器，以在直接队列上发布我的消息。 由于它是一个生产者应用程序，我必须创建我的交换和队列。 另外，我没有定义任何监听器bean，因为我在生产者端不需要它。 下面是我的rabbitmq-config.xml ：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit-1.5.xsd
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- Spring AMQP Admin -->
<rabbit:admin id="amqpAdmin"
    connection-factory="rabbitmqConnectionFactory"
    auto-startup="true" />

<!-- Spring AMQP Template -->
<rabbit:template id="amqpTemplate"
    connection-factory="rabbitmqConnectionFactory"
    routing-key="my.key" exchange="my.exchange" 
    channel-transacted="true"/>

<!-- Connection Factory -->
<rabbit:connection-factory id="rabbitmqConnectionFactory"
    host="${rabbitmq.host:localhost}" 
    port="${rabbitmq.port:5672}" 
    username="${rabbitmq.username}"
    password="${rabbitmq.password}" 
    virtual-host="${rabbitmq.vhost:/}"
    cache-mode="CONNECTION" 
    channel-cache-size="${rabbitmq.channel-cache-size:25}" />

<!-- Queue and Exchange -->
<rabbit:queue id="my.queue" durable="false"
    auto-declare="true" auto-delete="true" />

<rabbit:direct-exchange name="my.exchange" durable="false"
    auto-declare="true" auto-delete="true" declared-by="amqpAdmin">
    <rabbit:bindings>
        <rabbit:binding queue="my.queue" key="my.key"/>
    </rabbit:bindings>
</rabbit:direct-exchange>
</beans>

我只有一个简单的生成器类，它使用上面的amqpTemplate发送消息。 但是当我尝试运行我的生产者应用程序时，我得到的是： 在vhost中没有交换'my.exchange'/'ERROR

任何有关这方面的帮助将非常感激。 谢谢。

你的问题是：

cache-mode="CONNECTION" 

参见参考手册 ：

仅当CachingConnectionFactory缓存模式为CHANNEL （默认值）时才会执行自动声明。 存在此限制是因为exlusive和自动删除队列绑定到连接。

（哎呀！错字就在那里。很快就会修好:-)）
