news 2025/8/25 12:10:43

pom 依赖

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

写一个rabbitmq配置文件

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
@EnableRabbit
public class RabbitMQConfig {/*** 注入交换机* @return*/@Beanpublic FanoutExchange exchange1() {return new FanoutExchange ("自己的交换机");}/*** 注入队列* @return*/@Beanpublic Queue queue1() {return new Queue("名字随便取");}/*** 交换机和队列绑定* @return*/@Beanpublic Binding binding1() {return BindingBuilder.bind(queue1()).to(exchange1());}

消费者端代码

@Component
@Slf4j
public class MyConsumer {/***   队列名和配置文件中队列名一样即可消费到**/@RabbitListener(queues = "名字随便取")public void handleMessage(Message message) {byte[] body = message.getBody();// 指定编码方式将字节数组转换为字符串String content = null; // 获取消息体字节数组content = new String(body, "GBK");System.out.println(content);}}
