RabbitMQ embedded broker is not starting from spring boot application

Question

I am unable to send message in "CustomerQ" queue of rabbitmq broker. I have configured rabbitmq broker as embedded server through spring boot.

 package com.testlab.chapter2;

  import org.springframework.amqp.core.Queue;
  import org.springframework.amqp.rabbit.core.RabbitMessagingTemplate;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Lazy;
  import org.springframework.stereotype.Component;



  @Component 
  @Lazy
 class Sender {

  RabbitMessagingTemplate template;

  @Autowired
  Sender(RabbitMessagingTemplate template){
    this.template = template;
  }

  @Bean
  Queue queue() {
    return new Queue("CustomerQ", false);
   }

   public void send(String message){
    System.out.println(template.getRabbitTemplate().getConnectionFactory());

    template.convertAndSend("CustomerQ", message);
    }
  }

 **application.properties file configuration:**

  spring.rabbitmq.host=localhost
  spring.rabbitmq.port=5672
  spring.rabbitmq.username=guest
  spring.rabbitmq.password=guest

I am getting below error when code is trying to connect/put any message in queue Error:

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.messaging.MessagingException: java.net.ConnectException: Connection refused: connect; nested exception is org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect] with root cause

I will appreciate your help on this.

There's no such thing as an "embedded RabbitMQ broker".

You have to install and start it separately. It is not written in Java, it's Erlang.

What leads you to believe Boot embeds a broker?

Thanks Russell. I thought that spring boot supports RabbitMQ as well.My bad as I was not aware that it is written in java. I think spring boot supports embedded activemq broker as mentioned in below link: [link](http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-messaging.html). My code is working fine as I connected to rabbitmq external broker. – JavaSat Jan 21 '17 at 20:24
