在Java中配置RabbitMQ,需要遵循以下步骤:
1.添加依赖
在项目的pom.xml文件中添加RabbitMQ的Java客户端依赖:
<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>5.13.0</version>
</dependency>
2.创建连接工厂
创建一个连接工厂,用于创建与RabbitMQ服务器的连接:
import com.rabbitmq.client.ConnectionFactory;
public class RabbitMQConfig {
public static ConnectionFactory createConnectionFactory() {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost"); // 设置RabbitMQ服务器地址
factory.setPort(5672); // 设置RabbitMQ服务器端口
factory.setUsername("guest"); // 设置用户名
factory.setPassword("guest"); // 设置密码
return factory;
}
}
3.创建生产者和消费者
创建一个生产者,用于发送消息到RabbitMQ队列:
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 {
ConnectionFactory factory = RabbitMQConfig.createConnectionFactory();
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
String queueName = "test_queue";
channel.queueDeclare(queueName, false, false, false, null);
String message = "Hello, RabbitMQ!";
channel.basicPublish("", queueName, null, message.getBytes("UTF-8"));
System.out.println("Sent: '" + message + "'");
channel.close();
connection.close();
}
}
创建一个消费者,用于从RabbitMQ队列中接收消息:4
import com.rabbitmq.client.*;
import java.io.IOException;
import java.util.concurrent.TimeoutException;
public class Consumer {
public static void main(String[] args) throws IOException, TimeoutException {
ConnectionFactory factory = RabbitMQConfig.createConnectionFactory();
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
String queueName = "test_queue";
channel.queueDeclare(queueName, false, false, false, null);
System.out.println("Waiting for messages...");
DeliverCallback deliverCallback = (consumerTag, delivery) -> {
String message = new String(delivery.getBody(), "UTF-8");
System.out.println("Received: '" + message + "'");
};
channel.basicConsume(queueName, true, deliverCallback, consumerTag -> {});
}
}
4.运行生产者和消费者 文章来源:https://www.toymoban.com/news/detail-742260.html
分别运行Producer和Consumer类的main方法,生产者将消息发送到RabbitMQ队列,消费者将从队列中接收并处理消息。文章来源地址https://www.toymoban.com/news/detail-742260.html
