Spring Rabbit 队列 Xml：从 'Getter Bean' 获取 属性 时的 NoSuchBeanDefinition
Spring Rabbit Queue Xml: NoSuchBeanDefinition when Getting Property from 'Getter Bean'
我正在使用 xml 文件为 spring 兔子豆和配置配置 Spring 兔子。
我们使用自己的 propertyGetter class 来检索属性。在下面的spring兔子xml中，除了一个地方，它在任何地方都有效。这是为什么？
下面是xml。正在调用的 'propertyGetter.get(...)' 方法正在返回一个字符串 'my.queue'，但 RabbitMq xsd 解析器似乎正在尝试获取一个 bean。 (?).

应用程序首次初始化时的异常是“NoSuchBeanDefinitionException”，但我不确定为什么在方法调用返回字符串时解析 xml 的任何东西都期待一个 bean。
这是我在尝试部署应用程序时获得的堆栈跟踪：

其他注意事项：
这是一个使用 spring-rabbit-1.3.xsd
的 xml 文件
该解决方案不使用 spring 属性。这是以另一种方式管理属性。
它们是两个不同的东西。
对于 <bean/>，name 属性是 bean 名称的别名。如果没有提供 id，则使用第一个 name 作为 id。
对于<queue/>，name 属性是rabbitmq 代理中的队列名称； id 始终是 bean 名称，如果不存在，则会生成一个唯一的 bean 名称。
有一些现有的逻辑可以将 name 注册为别名，但这仅在解析时已知值时才有效（如您所见）。
事实上，这种别名的使用是不正确的，并且会导致其他问题 - 例如，你不能使用相同的 name 进行交换和排队 - 请参阅 this JIRA for a discussion about that.
为了解决这个问题，我们正在考虑完全删除别名并要求 id 属性为 bean 命名。
我相信你可以 work-around 你的问题，方法是给队列一个 id 并在你的侦听器容器 queues 属性中引用它，或者更改容器以使用 queue-names 反而。
