        cachingConnectionFactory.setHost("192.168.111.103");
        cachingConnectionFactory.setUsername("springboot");
        cachingConnectionFactory.setPassword("123456");
        cachingConnectionFactory.setPort(5672);
        return cachingConnectionFactory;
    }
 
    @Bean
    public AmqpAdmin amqpAdmin() {
        return new RabbitAdmin(connectionFactory());
    }
 
    @Bean
    public RabbitTemplate rabbitTemplate() {
        return new RabbitTemplate(connectionFactory());
    }
}

接受者

package com.master.rabbit;
 
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
 

@Component
public class Receiver {
 
    @RabbitListener(queues = "rabbit-queue")
    @RabbitHandler
    public void process(String message) {
        System.out.println("Receiver : " + message);
    }
 
}

@Component
public class Sender {
 
	@Autowired
	private RabbitTemplate rabbitTemplate;
 
	public void send() {
		String context = "hello " + new Date();
		System.out.println("Sender : " + context);
		this.rabbitTemplate.convertAndSend("rabbit-queue", context);
	}
 
}
