一基础验证

1. Maven依赖配置（pom.xml）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2. 生产者代码（Producer.java）

package com.example.rabbitmq.simple;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class Producer {
public static void main(String[] args) throws Exception {
// 创建连接工厂
ConnectionFactory connectionFactory = new ConnectionFactory();
// 设置主机地址
connectionFactory.setHost("localhost");
// 设置连接端口号：默认为 5672
connectionFactory.setPort(5672);
// 虚拟主机名称：默认为 /
connectionFactory.setVirtualHost("/");
// 设置连接用户名
connectionFactory.setUsername("guest");
// 设置连接密码
connectionFactory.setPassword("guest");

// 创建连接
Connection connection = connectionFactory.newConnection();
// 创建频道
Channel channel = connection.createChannel();

// 声明队列（持久化）
channel.queueDeclare("simple_queue", true, false, false, null);

// 要发送的信息
String message = "你好；小兔子！";

// 发送消息
channel.basicPublish("", "simple_queue", null, message.getBytes());
System.out.println("已发送消息: " + message);

// 关闭资源
channel.close();
connection.close();
}
}

3. 消费者代码（Comsumer.java）

package com.example.rabbitmq.simple;

import com.rabbitmq.client.*;

import java.io.IOException;

public class Consumer {

public static void main(String[] args) throws Exception {

// 创建连接工厂

ConnectionFactory factory = new ConnectionFactory();

// 设置参数

factory.setHost("localhost");

factory.setPort(5672);

factory.setVirtualHost("/");

factory.setUsername("guest");

factory.setPassword("guest");

// 创建连接

Connection connection = factory.newConnection();

// 创建Channel

Channel channel = connection.createChannel();

// 声明队列

channel.queueDeclare("simple_queue", true, false, false, null);

// 接收消息

DefaultConsumer consumer = new DefaultConsumer(channel) {

@Override

public void handleDelivery(String consumerTag, Envelope envelope,

AMQP.BasicProperties properties, byte[] body) throws IOException {

System.out.println("consumerTag: " + consumerTag);

System.out.println("Exchange: " + envelope.getExchange());

System.out.println("RoutingKey: " + envelope.getRoutingKey());

System.out.println("properties: " + properties);

System.out.println("body: " + new String(body));

}

};

// 消费消息

channel.basicConsume("simple_queue", false, consumer);

}

}
