application.yml 配置信息

spring:
  rabbitmq:
  ####連接地址
    host: 127.0.0.1
   ####端口號   
    port: 5672
   ####賬號

交換機綁定隊列

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.context.annotation.Bean;
import org.springframework.stereotype.Component;

//Fanout 類型 發佈訂閱模式
@Component
public class FanoutConfig {

	// 郵件隊列
	private String FANOUT_EMAIL_QUEUE = "fanout_email_queue";

	// 短信隊列
	private String FANOUT_SMS_QUEUE = "fanout_sms_queue";
	// fanout 交換機
	private String EXCHANGE_NAME = "fanoutExchange";

	// 1.定義郵件隊列
	@Bean
	public Queue fanOutEamilQueue() {
		return new Queue(FANOUT_EMAIL_QUEUE);
	}

	// 2.定義短信隊列
	@Bean
	public Queue fanOutSmsQueue() {
		return new Queue(FANOUT_SMS_QUEUE);
	}

	// 2.定義交換機
	@Bean
	FanoutExchange fanoutExchange() {
		return new FanoutExchange(EXCHANGE_NAME);
	}

	// 3.隊列與交換機綁定郵件隊列
	@Bean
	Binding bindingExchangeEamil(Queue fanOutEamilQueue, FanoutExchange fanoutExchange) {
		return BindingBuilder.bind(fanOutEamilQueue).to(fanoutExchange);
	}

	// 4.隊列與交換機綁定短信隊列
	@Bean
	Binding bindingExchangeSms(Queue fanOutSmsQueue, FanoutExchange fanoutExchange) {
		return BindingBuilder.bind(fanOutSmsQueue).to(fanoutExchange);
	}
}

生產者投遞消息

import java.util.UUID;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageBuilder;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.alibaba.fastjson.JSONObject;

@Component
public class FanoutProducer {
	@Autowired
	private AmqpTemplate amqpTemplate;

	public void send(String queueName) {
		JSONObject jsonObject = new JSONObject();
		jsonObject.put("email", "[email protected]");
		jsonObject.put("timestamp", System.currentTimeMillis());
		String jsonString = jsonObject.toJSONString();
		System.out.println("jsonString:" + jsonString);
		// 設置消息唯一id 保證每次重試消息id唯一
		Message message = MessageBuilder.withBody(jsonString.getBytes())
				.setContentType(MessageProperties.CONTENT_TYPE_JSON).setContentEncoding("utf-8")
				.setMessageId(UUID.randomUUID() + "").build();
		amqpTemplate.convertAndSend(queueName, message);
	}
}

 

控制層調用代碼

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.itmayiedu.rabbitmq.FanoutProducer;

@RestController
public class ProducerController {
	@Autowired
	private FanoutProducer fanoutProducer;

	@RequestMapping("/sendFanout")
	public String sendFanout(String queueName) {
		fanoutProducer.send(queueName);
		return "success";
	}
}
