使用Spring AMQP,当对方法rabbitTemplate.send(message)
的调用返回时(来自org.springframework.amqp.rabbit.core.RabbitTemplate类),我们可以确定该消息已在RabbitMQ上传递和复制集群?

更新:这不是正确答案。请参阅@GaryRussell的答案
如果您的意思是发布商与RabbitMQ之间唯一的沟通 好的。您不必执行除此之外的任何操作,以确保消息存储和复制是RabbitMQ工作的一部分。
如果发送邮件有任何问题,请记得catch var element =
new Drawing(
new DW.Inline(
new DW.Extent() { Cx = 990000L, Cy = 792000L },
new DW.EffectExtent()
{
LeftEdge = 0L,
TopEdge = 0L,
RightEdge = 0L,
BottomEdge = 0L

new DW.DocProperties()

Name = "Picture 1"
},

不,不。 AMQP是一种异步协议。为了保证交付,您需要使用Publisher Confirms and Returns - 即使这样,确认(或返回)也会在另一个线程上返回。
