Spring AMQP 1.6 和 1.6.0.RC1 发布

Spring AMQP 1.6 和 1.6.0.RC1 发布了，主要改进记录如下：

A new jar spring-rabbit-test containing a test harness to help with testing@RabbitListener methods; see the testing chapter.
Multiple @RabbitListener annotations on a method (when using Java 8) and the@RabbitListeners annotation (for pre-Java 8), each allowing the same method to be the listener method for multiple listener containers.
Full support for the Delayed Message Exchange RabbitMQ plugin.
An AsyncRabbitTemplate returning ListenableFuture<?> for request/reply messaging.
An option to publish ApplicationEvents when listener containers go idle.
The caching connection factory now exposes cache statistics
@RabbitListener methods now communicate type information to the message converter for inbound messages. This means, for example, the Jackson2JsonMessageConverter no longer needs a custom class mapper when a message without type information in the headers is received (e.g. from a sender that is not a Spring AMQP app). Instead, the @RabbitListenermethod parameter type is used in the conversion. In addition, the Method and bean are also made available via message properties to custom converters.
