    简单使用

    1.导入依赖

      <dependencies>
            <!-- https://mvnrepository.com/artifact/com.rabbitmq/amqp-client -->
            <dependency>
                <groupId>com.rabbitmq</groupId>
                <artifactId>amqp-client</artifactId>
                <version>5.0.0</version>
            </dependency>

            <dependency>
                <groupId>org.springframework.amqp</groupId>
                <artifactId>spring-rabbit</artifactId>
                <version>1.4.6.RELEASE</version>
            </dependency>
        </dependencies>

    2.消息生产者

      import com.rabbitmq.client.*;

    import java.util.HashMap;
    import java.util.Map;

    /**
    * 消息的生产者
    * 将想要发送的消息加入消息队列
    * @author ZX

    */
    public class Producer {
        public  static  void main(String[]args) throws Exception{
            //1、创建链接对象
            ConnectionFactory factory = new ConnectionFactory();
            //rabbitmq所在ip,用户名密码
            factory.setHost("192.168.0.17");
            factory.setUsername("admin1");
            factory.setPort(5672);
            factory.setPassword("123456");
            Connection connection = factory.newConnection();
            //创建一个频道
            Channel channel = connection.createChannel();
            //声明一个dirent模式的交换机
            /**channel.exchangeDeclare(String exchange,String type,boolean durable,boolean autodelete....)
             参数1:exchange 交换机对象的名称
             参数2 type
             BuiltinExchangeType. DIRECT("direct"),定向发送消息
             BuiltinExchangeType. FANOUT("fanout"),会向所有的queue广播所有收到的消息。如log系统可使用此模式
             BuiltinExchangeType. TOPIC("topic"),
             BuiltinExchangeType. HEADERS("headers");
             参数3:durable:如果设置了true,本交换机在重启后也会生存(实际上不一定靠谱,设置为true就好)
             参数n:。。。。。。。
             */
            channel.exchangeDeclare("exchange_name", BuiltinExchangeType.DIRECT,true);
            //声明一个非持久化自动删除的队列,如果该队列不在被使用就删除他 zhe
            channel.queueDeclare("queue_name",false,false,true,null);
            //将绑定到改交换机
            channel.queueBind("queue_name","exchange_name","route_key");
            //声明一个消息头部
            AMQP.BasicProperties.Builder builder= new AMQP.BasicProperties.Builder();
            Map<String,Object> header=new HashMap<String, Object>();
            header.put("charset","utf-8");
            builder.headers(header);
            AMQP.BasicProperties basicProperties=builder.build();
            //将消息发出去
            channel.basicPublish("exchange_name","route_key",false,basicProperties,"消息的内容".getBytes());
            for (int i=0;i<100;i++){
                channel.basicPublish("exchange_name","route_key",false,basicProperties,("消息的内容"+i).getBytes());
            }
        }

    }

    3.消息消费者

    import com.rabbitmq.client.*;
    import com.rabbitmq.client.BuiltinExchangeType;
    import java.io.IOException;
    
    public class Consumer {
        public  static  void main(String[]args) throws Exception{
            //1、创建链接对象
            ConnectionFactory factory = new ConnectionFactory();
            factory.setHost("192.168.0.17");
            factory.setUsername("admin1");
            factory.setPort(5672);
            factory.setPassword("123456");
            Connection connection = factory.newConnection();
            Channel channel = connection.createChannel();
            //声明一个dirent模式的交换机
            /**channel.exchangeDeclare(String exchange,String type,boolean durable,boolean autodelete....)
                    参数1:exchange 交换机对象的名称
                    参数2 type
                    BuiltinExchangeType. DIRECT("direct"),
                    BuiltinExchangeType.        FANOUT("fanout"),
                    BuiltinExchangeType.    TOPIC("topic"),
                    BuiltinExchangeType.    HEADERS("headers");
             参数3:durable:如果设置了true,本交换机在重启后也会生存(实际上不一定靠谱,设置为true就好)
             参数n:。。。。。。。
            */
            channel.exchangeDeclare("exchange_name",BuiltinExchangeType.DIRECT,true);
            //声明一个非持久化自动删除的队列,如果该队列不在被使用就删除他
            channel.queueDeclare("queue_name",false,false,true,null);
            //将绑定到改交换机
            channel.queueBind("queue_name","exchange_name","route_key");
            //创建消费者对象
            com.rabbitmq.client.Consumer consumer = new DefaultConsumer(channel) {
                @Override
                public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties,
                                           byte[] body) throws IOException {
                    String message = new String(body, "UTF-8");
                    System.out.println(" [x] Received '" + message + "'");
                }
            };
            channel.basicConsume("queue_name", true, consumer);
        }
    }
