当我们尝试从java代码访问连接工厂并执行destroy方法时，连接不会关闭。此外，当我们检查该连接工厂的打开连接时，它显示没有打开的连接，但实际上rabbitmq有一个打开的连接。

RabbitTemplate rabbitTemplate = (RabbitTemplate) rabbitTemplateMap.get(String.valueOf(key));
CachingConnectionFactory cachingConnectionFactory = (CachingConnectionFactory) rabbitTemplate.getConnectionFactory();
cachingConnectionFactory.destroy();

以上代码段无法成功关闭连接。我们使用以下依赖项：

<dependency>
     <groupId>org.springframework.amqp</groupId>
     <artifactId>spring-rabbit</artifactId>
     <version>1.3.9.RELEASE</version>
</dependency>

出现这种要求是因为一种特殊的情况，当连接被阻塞时，我们希望提供转换到替代经纪人的选项。因此，我们必须关闭当前连接并与替代代理建立新连接。如果您需要更多信息，请与我们联系。

1.3.9是一个相当旧的版本（当前版本是1.6.1）。

但是，我不知道使用destroy()方法关闭连接有任何问题。在1.5中，我们添加了resetConnection()，其名称不太可怕，但与destroy()的内容相同。

如果您有任何侦听器容器，重置后将立即重新建立连接;同样，如果使用模板发布消息，则将重新创建连接。

如果您仍然觉得有问题，我建议您使用wirehark或tcpdump等网络监视器来查看正在发生的事情。
