智能图像处理平台：RabbitMQ配置

前面我们用Docker拉了rabbitMQ，并集成进了springboot，现在我们先写配置类：
java 复制代码
package com.llpp.config;

import com.llpp.service.impl.ImageServiceImpl;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitMQConfig {

    public static final String EXCHANGE_NAME = "image_processing_exchange";
    public static final String QUEUE_NAME = "image_processing_queue";
    public static final String ROUTING_KEY = "image.processing";

    @Autowired
    private ConnectionFactory connectionFactory;

    @Bean
    public TopicExchange exchange() {
        return new TopicExchange(EXCHANGE_NAME);
    }

    @Bean
    public Queue queue() {
        return new Queue(QUEUE_NAME, true);
    }

    @Bean
    public Binding binding(Queue queue, TopicExchange exchange) {
        return BindingBuilder.bind(queue).to(exchange).with(ROUTING_KEY);
    }

    @Bean
    public SimpleMessageListenerContainer messageListenerContainer() {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        container.setQueueNames(QUEUE_NAME);
        container.setMessageListener(new MessageListenerAdapter(new ImageServiceImpl()));
        return container;
    }
}
