注册rabbitAdmin和connectionFactory
package com.edu.mq.spring;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* 注册到spring容器
*/
@Configuration
public class MQConfig {
/**
* 注册ConnectionFactory工厂类，这里是spring封装的工厂类，和之前的rabbitclient的工程类
* 不是同一个
* org.springframework.amqp.rabbit.connection.ConnectionFactory;
* @return
*/
@Bean
public ConnectionFactory connectionFactory() {
CachingConnectionFactory factory = new CachingConnectionFactory();
factory.setUri("amqp://guest:guest@localhost:5672");
return factory;
}
@Bean
public RabbitAdmin rabbitAdmin(ConnectionFactory connectionFactory) {
return new RabbitAdmin(connectionFactory);
}
}
RabbitAdmin的具体操作
package com.edu.mq.spring;
import org.springframework.amqp.core.*;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Component;
import java.util.HashMap;
import java.util.Map;
/**
* 类说明：

*/
@ComponentScan
public class RabbmitAdminDetail {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(RabbmitAdminDetail.class);
RabbitAdmin rabbit = context.getBean(RabbitAdmin.class);
System.out.println(rabbit);
/**
* 创建四种不同的exchange，这里的exchange都是用spring-amqp封装的exchange，并指定exchange的属性
* 以下代码都可以重复执行
*/
rabbit.declareExchange(new DirectExchange("log.direct.exchange", true, false));
rabbit.declareExchange(new TopicExchange("log.topic.exchange", true, false));
rabbit.declareExchange(new FanoutExchange("log.fanout.exchange", true, false));
rabbit.declareExchange(new HeadersExchange("log.headers.exchange", true, false));
// rabbit.deleteExchange("log.headers.exchange");
/**
* 创建queue和创建exchange一样
*/
rabbit.declareQueue(new Queue("log.debug", true));
rabbit.declareQueue(new Queue("log.info", true));
rabbit.declareQueue(new Queue("log.error", true));
// rabbit.deleteQueue("log.error");
/**
* 清空某个队列中的消息，注意，清空的消息并没有被消费
*/
rabbit.purgeQueue("log.info", false);
/**
* 声明绑定，1，exchange和queue绑定；2，exchange和exchange绑定及不同的绑定方式
*/
rabbit.declareBinding(new Binding("log.debug", Binding.DestinationType.QUEUE, "log.direct.exchange", "debug", new HashMap<>()));
rabbit.declareBinding(new Binding("log.info", Binding.DestinationType.QUEUE, "log.direct.exchange", "info", new HashMap<>()));
rabbit.declareBinding(new Binding("log.error", Binding.DestinationType.QUEUE, "log.direct.exchange", "error", new HashMap<>()));
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.debug")).to(new TopicExchange("log.topic.exchange")).with("debug.*"));
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.info")).to(new TopicExchange("log.topic.exchange")).with("info.#"));
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.error")).to(new TopicExchange("log.topic.exchange")).with("error.#"));
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.debug")).to(new FanoutExchange("log.fanout.exchange")));
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.info")).to(new FanoutExchange("log.fanout.exchange")));
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.error")).to(new FanoutExchange("log.fanout.exchange")));
Map<String, Object> headerValues = new HashMap<>();
headerValues.put("type", 1);
headerValues.put("size", 10);
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.debug")).to(new HeadersExchange("log.headers.exchange")).whereAll(headerValues).match());
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.info")).to(new HeadersExchange("log.headers.exchange")).whereAny(headerValues).match());
Map<String, Object> headerValues2 = new HashMap<>();
headerValues2.put("type", 2);
headerValues2.put("size", 10);
rabbit.declareBinding(BindingBuilder.bind(new Queue("log.error")).to(new HeadersExchange("log.headers.exchange")).whereAll(headerValues2).match());
/**
* 删除绑定
*/
// rabbit.removeBinding(BindingBuilder.bind(new Queue("log.debug")).to(new FanoutExchange("log.fanout.exchange")));
//exchange和exchange的binding
// rabbit.declareBinding(new Binding("log.all", Binding.DestinationType.EXCHANGE, "log.info", "info", new HashMap<>()));
// rabbit.declareBinding(BindingBuilder.bind(new TopicExchange("sms.all")).to(new TopicExchange("sms.reg")).with("reg"));
context.close();
}
}
如上可以看到，RabbitAdmin只是对RabbitTemplent的一个封装使用，完成exchange，queue，binding的创建，删除等操作。
