RabbitMQ入门学习(2) 入门安装 测试使用

使用docker安装

拉取带manage版本的镜像

docker pull rabbitmq:management

带配置用户名密码 运行镜像

docker run -d --name rabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management

15672为web管理面板接口
1873为应用程序访问接口
这里配置用户名密码都为admin
访问15672接口测试

安装成功!

编写java程序互动

创建boot项目 导入依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
            <version>2.5.3</version>
        </dependency>

编写生产者类

public class Producer {
    public static void main(String[] args) {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("192.168.198.129");
        connectionFactory.setPort(5672);
        connectionFactory.setUsername("admin");
        connectionFactory.setPassword("admin");
        connectionFactory.setVirtualHost("/");
        Connection connection = null;
        Channel channel = null;
        try {
            //创建连接
            connection = connectionFactory.newConnection("生产者");
            //获取通道
            channel = connection.createChannel();
            //通过通道声明队列,创建交换机等一系列事情
            String queueName = "queue1";
            channel.queueDeclare(queueName,false,false,false,null);
            String message = "Hello rabbitmq";
            channel.basicPublish("",queueName,null,message.getBytes());
            System.out.println("发送成功");
        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }
        finally {
            //关闭通道
            if(channel != null && channel.isOpen()){
                try {
                    channel.close();
                }
                catch (Exception e){
                    e.printStackTrace();
                }
            }

            if(connection != null && connection.isOpen()){
                try {
                    connection.close();
                }
                catch (Exception e){
                    e.printStackTrace();
                }
            }
        }
    }
}

编写消费者类

public class Consumer {
    public static void main(String[] args) {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("192.168.198.129");
        connectionFactory.setPort(5672);
        connectionFactory.setUsername("admin");
        connectionFactory.setPassword("admin");
        connectionFactory.setVirtualHost("/");
        Connection connection = null;
        Channel channel = null;
        try {
            //创建连接
            connection = connectionFactory.newConnection("消费者");
            //获取通道
            channel = connection.createChannel();
            //通过通道声明队列,创建交换机等一系列事情
            channel.basicConsume("queue1", true, new DeliverCallback() {
                @Override
                public void handle(String s, Delivery delivery) throws IOException {
                    System.out.println("收到消息为" + new String(delivery.getBody(), "UTF-8"));
                }
            }, new CancelCallback() {
                @Override
                public void handle(String s) throws IOException {
                    System.out.println("收取消息失败");
                }
            });
            //卡一下
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }
        finally {
            //关闭通道
            if(channel != null && channel.isOpen()){
                try {
                    channel.close();
                }
                catch (Exception e){
                    e.printStackTrace();
                }
            }

            if(connection != null && connection.isOpen()){
                try {
                    connection.close();
                }
                catch (Exception e){
                    e.printStackTrace();
                }
            }
        }
    }
}
