RABBITMQ Java code Simple to use

introduce pom content:

	<dependency>
		<groupId>com.rabbitmq</groupId>
		<artifactid>amqp-client</ artifactid>
		<version>3.3.4</version>
	</dependency>

send-side code:

Package com;
Import Com.rabbitmq.client.Channel;
Import com.rabbitmq.client.Connection;
Import Com.rabbitmq.client.ConnectionFactory;

Import com.rabbitmq.client.MessageProperties;
	public class Producer {private static String QueueName = "Queue2";
		public static void Main (string[] args) throws exception{connectionfactory factory = new ConnectionFactory ();
		Factory.sethost ("127.0.0.1");
		Factory.setusername ("admin");
		Factory.setpassword ("admin");
		
		Connection Connection = Factory.newconnection ();
		
		Channel Channel = Connection.createchannel ();  
        
        
        Channel.queuedeclare (QueueName, True, False, false, NULL); for (int i = 0; i < i++) {//messages sent String message = "Hello world!"  
            +i; Send a message to the queue Channel.basicpublish ("", QueueName, Messageproperties.persistent_text_plain, Message.getbytes ()  
            );  
System.out.println ("[X] Sent '" + Message + "'");
		Thread.Sleep (1000);//Close the channel and connect Channel.close (); 
		
	Connection.close ();
 }

}

Receive-side code:

Package com;
Import Com.rabbitmq.client.Channel;
Import com.rabbitmq.client.Connection;
Import Com.rabbitmq.client.ConnectionFactory;

Import Com.rabbitmq.client.QueueingConsumer;

	public class Consumer {private static String QueueName = "Queue2";
		public static void Main (string[] args) throws Exception {ConnectionFactory factory = new ConnectionFactory ();
		Factory.sethost ("127.0.0.1");
		Factory.setusername ("admin");
		Factory.setpassword ("admin");
		Connection Connection = Factory.newconnection ();

		Channel Channel = Connection.createchannel ();
		Declares queues, primarily to prevent message recipients from running the program, and to create queues when they do not exist.
		Channel.queuedeclare (QueueName, True, False, false, NULL); System.out.println (Consumer.class.hashCode () + "[*] waiting for messages."

		To exit Press CTRL + C ");

		Create queue consumer Queueingconsumer consumer = new Queueingconsumer (channel);
		Set maximum service message receive quantity int prefetchcount = 1;

		Channel.basicqos (Prefetchcount); Boolean ack = FALSE; Whether to automatically confirm the message was successfully consumed Channel.basicconsume (QueueName, aCK, consumer); Specify consumption queue while (true) {//Nextdelivery is a blocking method (internal implementation is actually a take method for blocking queues) queueingconsumer.delivery Delivery = Consumer

			String message = new String (Delivery.getbody ());

			System.out.println ("[X] Received '" + Message + "'");
			Channel.basicack (Delivery.getenvelope (). Getdeliverytag (), false);
