spring整合rabbitmq

1、依赖
<!-- https://mvnrepository.com/artifact/org.springframework.amqp/spring-rabbit -->
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.7.4.RELEASE</version>
</dependency>
2、初始化配置

#RabbitMQ消息队列
rabbitmq.host=10.0.0.236
rabbitmq.port=5672
rabbitmq.username=root
rabbitmq.password=123456

package com.lv.qggz.man.mq;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.beans.factory.config.ConfigurableBeanFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;

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

/**
* @Author: sh
* @Description: RabbitConfig
* @Date: 14:46 2019/11/5
*/
@Configuration
public class RabbitConfig {

@Value("${rabbitmq.host}")
private String host;

@Value("${rabbitmq.port}")
private int port;

@Value("${rabbitmq.username}")
private String username;

@Value("${rabbitmq.password}")
private String password;

public static final String QUEUE = "gs_queue";

public static final int ALIVETIME = 50000;

@Bean
public CachingConnectionFactory connectionFactory() {
CachingConnectionFactory connectionFactory = new CachingConnectionFactory(host,port);
connectionFactory.setUsername(username);
connectionFactory.setPassword(password);
connectionFactory.setVirtualHost("/");
connectionFactory.setPublisherConfirms(true);
return connectionFactory;
}

@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public RabbitTemplate rabbitTemplate() {
RabbitTemplate template = new RabbitTemplate(connectionFactory());
return template;
}

@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public AmqpTemplate myMqpTemplate() {
RabbitTemplate template = new RabbitTemplate(connectionFactory());
return template;
}

@Bean
public Queue cretaeQueue(){
// return new Queue(QUEUE,true);
Map<String, Object> argMap = new HashMap<>();
// 设置消息存活时间
argMap.put("x-message-ttl",ALIVETIME);
return new Queue(QUEUE, true, false, false, argMap);

}
}
3、生产
package com.lv.qggz.man.mq;

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.AmqpException;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

/**
* @Author: sh
* @Description: MqSender
* @Date: 10:34 2019/11/4
*/
@Slf4j
@Service("mqSenderService")
public class MqSenderService {

@Resource
AmqpTemplate myMqpTemplate;

public String sendMsgToQueue(Object message) {
try {
log.info("sendMsgToQueue--messgae:" + message);
//amqpTemplate.convertAndSend(MQConfig.QUEUE, msg);
return myMqpTemplate.convertSendAndReceive(RabbitConfig.QUEUE, message).toString();
} catch (AmqpException e) {
return null;
}

}

public void sendMsg(Object message) {
log.info("send message:" + message);
myMqpTemplate.convertAndSend(RabbitConfig.QUEUE, message);
log.info("sendMsg（）---消息发送成功！");

}

}
4、消费
package dhht.seal.hn.gsgate.rabbitmq;

import dhht.seal.hn.gsgate.service.CropQueryService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

/**
* @Author: sh
* @Description: MqReceiver
* @Date: 10:40 2019/11/4
*/
@Service
public class MqReceiverService {

private static Logger log = LoggerFactory.getLogger(MqReceiverService.class);

@Resource
private CropQueryService cropQueryService;

@RabbitListener(queues = RabbitMqConfig.QUEUE)
@SendTo(RabbitMqConfig.QUEUE)
public String receiveQueueMsg(String message) {
log.info("接收到队列消息：" + message);
// 业务处理代码，工商拉取入库
String resJson = cropQueryService.crropQuery(message);
return resJson;
}
}
