调用amqp消息队列不是异步的

Question

Here is my code:

class ParsepdfClient 
#!/usr/bin/env ruby
# encoding: utf-8

require 'amqp'
require "rubygems"
require 'mq'

  def self.test

    EventMachine.run do
        connection = AMQP.connect(:host => '127.0.0.1')
        puts "Connected to AMQP broker. Running #{AMQP::VERSION} version of the gem..."

        channel = AMQP::Channel.new(connection)
        queue = channel.queue("amqpgem.examples.helloworld", :auto_delete => true)
        exchange = channel.direct("")

        queue.subscribe do |payload|
            sleep(1.minutes)
            puts "Received a message: #{payload}. Disconnecting..."
            connection.close { EventMachine.stop }
        end

        exchange.publish "Hello, world!", :routing_key => queue.name
    end   
  end
end

I'm using Rabbitmq as a broker with rails amqp gem . Now I'm calling :

ParsepdfClient.test from a controller.

From my understanding my call shouldn't sleep for a minute but it waits for a minute and it outputs

"Received a message: Hello, world!. Disconnecting..."

And then it executes rest of my code of controller. Shouldn't the call be asynchronous? If not how can I make it asynchronous?

What I mean is that shouldn't it execute the rest of the code of my controller after outputting

Connected to AMQP broker. Running #{AMQP::VERSION} version of the gem...

I managed to implement Rabbitmq in rails successfully with the help of my senior. If any one is having any issue I have written a blog post here .
