09---------RabbitMq的四种交换机模式

首先要导入依赖

<!-- 添加rabbitmq依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>

接着配置相关配置文件

#rabbitmq
spring.rabbitmq.host=自己的主机或者本地(localhost)
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin
spring.rabbitmq.virtual-host=/
#\u6D88\u8D39\u8005\u6570\u91CF
spring.rabbitmq.listener.simple.concurrency= 10
spring.rabbitmq.listener.simple.max-concurrency= 10
#\u6D88\u8D39\u8005\u6BCF\u6B21\u4ECE\u961F\u5217\u83B7\u53D6\u7684\u6D88\u606F\u6570\u91CF
spring.rabbitmq.listener.simple.prefetch= 1
#\u6D88\u8D39\u8005\u81EA\u52A8\u542F\u52A8
spring.rabbitmq.listener.simple.auto-startup=true
#\u6D88\u8D39\u5931\u8D25\uFF0C\u81EA\u52A8\u91CD\u65B0\u5165\u961F
spring.rabbitmq.listener.simple.default-requeue-rejected= true
#\u542F\u7528\u53D1\u9001\u91CD\u8BD5
spring.rabbitmq.template.retry.enabled=true 
spring.rabbitmq.template.retry.initial-interval=1000 
spring.rabbitmq.template.retry.max-attempts=3
spring.rabbitmq.template.retry.max-interval=10000
spring.rabbitmq.template.retry.multiplier=1.0

1.使用MQConfig

package MiaoSha.rabbitmq;


import java.util.HashMap;
import java.util.Map;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.HeadersExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MQConfig {
	public static final String MIAOSHA_QUEUE = "miaosha.queue";
	public static final String QUEUE = "queue";
	public static final String TOPIC_QUEUE1 = "topic.queue1";
	public static final String TOPIC_QUEUE2 = "topic.queue2";
	public static final String HEADER_QUEUE = "header.queue";
	public static final String TOPIC_EXCHANGE = "topicExchage";
	public static final String FANOUT_EXCHANGE = "fanoutxchage";
	public static final String HEADERS_EXCHANGE = "headersExchage";
	
	/**
	 * Direct模式 交换机Exchange
	 * */
	@Bean
	public Queue queue() {
		return new Queue(QUEUE, true);
	}
	
	/**
	 * Topic模式 交换机Exchange
	 * */
	@Bean
	public Queue topicQueue1() {
		return new Queue(TOPIC_QUEUE1, true);
	}
	@Bean
	public Queue topicQueue2() {
		return new Queue(TOPIC_QUEUE2, true);
	}
	@Bean
	public TopicExchange topicExchage(){
		return new TopicExchange(TOPIC_EXCHANGE);
	}
	@Bean
	public Binding topicBinding1() {
		return BindingBuilder.bind(topicQueue1()).to(topicExchage()).with("topic.key1");
	}
	@Bean
	public Binding topicBinding2() {
		return BindingBuilder.bind(topicQueue2()).to(topicExchage()).with("topic.#");
	}
	/**
	 * Fanout模式 交换机Exchange
	 * */
	@Bean
	public FanoutExchange fanoutExchage(){
		return new FanoutExchange(FANOUT_EXCHANGE);
	}
	@Bean
	public Binding FanoutBinding1() {
		return BindingBuilder.bind(topicQueue1()).to(fanoutExchage());
	}
	@Bean
	public Binding FanoutBinding2() {
		return BindingBuilder.bind(topicQueue2()).to(fanoutExchage());
	}
	/**
	 * Header模式 交换机Exchange
	 * */
	@Bean
	public HeadersExchange headersExchage(){
		return new HeadersExchange(HEADERS_EXCHANGE);
	}
	@Bean
	public Queue headerQueue1() {
		return new Queue(HEADER_QUEUE, true);
	}
	@Bean
	public Binding headerBinding() {
		Map<String, Object> map = new HashMap<String, Object>();
		map.put("header1", "value1");
		map.put("header2", "value2");
		return BindingBuilder.bind(headerQueue1()).to(headersExchage()).whereAll(map).match();
	}
	
	
}

2.MQReceiver

package MiaoSha.rabbitmq;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Service;

@Service
public class MQReceiver {

	@RabbitListener(queues=MQConfig.QUEUE)
	public void receive(String message) {
		log.info("receive message:"+message);
	}
	
	@RabbitListener(queues=MQConfig.TOPIC_QUEUE1)
	public void receiveTopic1(String message) {
		log.info(" topic  queue1 message:"+message);
	}
	
	@RabbitListener(queues=MQConfig.TOPIC_QUEUE2)
	public void receiveTopic2(String message) {
		log.info(" topic  queue2 message:"+message);
	}
	
	@RabbitListener(queues=MQConfig.HEADER_QUEUE)
	public void receiveHeaderQueue(byte[] message) {
		log.info(" header  queue message:"+new String(message));
	}
	
	
}

3.MQSender

	public void send(Object message) {
	String msg = RedisService.beanToString(message);
	log.info("send message:"+msg);
	amqpTemplate.convertAndSend(MQConfig.QUEUE, msg);
}

public void sendTopic(Object message) {
	String msg = RedisService.beanToString(message);
	log.info("send topic message:"+msg);
	amqpTemplate.convertAndSend(MQConfig.TOPIC_EXCHANGE, "topic.key1", msg+"1");
	amqpTemplate.convertAndSend(MQConfig.TOPIC_EXCHANGE, "topic.key2", msg+"2");
}

public void sendFanout(Object message) {
	String msg = RedisService.beanToString(message);
	log.info("send fanout message:"+msg);
	amqpTemplate.convertAndSend(MQConfig.FANOUT_EXCHANGE, "", msg);
}

public void sendHeader(Object message) {
	String msg = RedisService.beanToString(message);
	log.info("send fanout message:"+msg);
	MessageProperties properties = new MessageProperties();
	properties.setHeader("header1", "value1");
	properties.setHeader("header2", "value2");
	Message obj = new Message(msg.getBytes(), properties);
	amqpTemplate.convertAndSend(MQConfig.HEADERS_EXCHANGE, "", obj);
}

4.controller调用

	@RequestMapping("/mq/header")
  @ResponseBody
  public Result<String> header() {
		sender.sendHeader("hello,imooc");
      return Result.success("Hello,world");
  }
	
	@RequestMapping("/mq/fanout")
  @ResponseBody
  public Result<String> fanout() {
		sender.sendFanout("hello,imooc");
      return Result.success("Hello,world");
  }
	
	@RequestMapping("/mq/topic")
  @ResponseBody
  public Result<String> topic() {
		sender.sendTopic("hello,imooc");
      return Result.success("Hello,world");
  }
	
	@RequestMapping("/mq")
  @ResponseBody
  public Result<String> mq() {
		sender.send("hello,imooc");
      return Result.success("Hello,world");
  }
