Spring-boot JMS 发送消息慢的问题解决

1、在《ActiveMQ 基于zookeeper的主从（levelDB Master/Slave）搭建以及Spring-boot下使用》中，采用以下代码进行JMS消息发送：

@Servicepublic class Producer { @Autowired private JmsMessagingTemplate jmsTemplate; public void sendMessage(Destination destination, final String message){ jmsTemplate.convertAndSend(destination, message); }}

经使用JMeter进行压力测试，发现JMS的发送消息特别慢。

2、下面通过自定义CachingConnectionFactory解决。

（1）SenderConfig.java

package com.example.springbootactivemq.jms;import org.apache.activemq.ActiveMQConnectionFactory;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.jms.connection.CachingConnectionFactory;import org.springframework.jms.core.JmsTemplate;/** * Created by yan on 2017/8/3. */@Configurationpublic class SenderConfig { @Value("${spring.activemq.broker-url}") private String brokerUrl; @Bean public ActiveMQConnectionFactory activeMQConnectionFactory() { ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(); activeMQConnectionFactory.setBrokerURL(brokerUrl); return activeMQConnectionFactory; } @Bean public CachingConnectionFactory cachingConnectionFactory() { return new CachingConnectionFactory(activeMQConnectionFactory()); } @Bean public JmsTemplate jmsTemplate() { return new JmsTemplate(cachingConnectionFactory()); } @Bean public Sender sender() { return new Sender(); }}

（2）Sender.java

package com.example.springbootactivemq.jms;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jms.core.JmsTemplate;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.Session;import javax.jms.TextMessage;/** * Created by yan on 2017/8/3. */public class Sender { @Autowired private JmsTemplate jmsTemplate; public void send(final String destination, final String message){ this.jmsTemplate.convertAndSend(destination, message); }}

（3）Receiver.java

package com.example.springbootactivemq.jms;import org.springframework.jms.annotation.JmsListener;import org.springframework.jms.listener.SessionAwareMessageListener;import org.springframework.jms.support.JmsUtils;import javax.jms.JMSException;import javax.jms.MessageProducer;import javax.jms.Session;import javax.jms.TextMessage;/** * Created by yan on 2017/8/3. */public class Receiver implements SessionAwareMessageListener<TextMessage> { @JmsListener(destination = "${queue.destination}") public void receive(String message) { try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } }}

（4）ReceiverConfig.java

package com.example.springbootactivemq.jms;import org.apache.activemq.ActiveMQConnectionFactory;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.jms.annotation.EnableJms;import org.springframework.jms.config.DefaultJmsListenerContainerFactory;/** * Created by yan on 2017/8/3. */@Configuration@EnableJmspublic class ReceiverConfig { @Value("${spring.activemq.broker-url}") private String brokerUrl; @Bean public ActiveMQConnectionFactory activeMQConnectionFactory() { ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(); activeMQConnectionFactory.setBrokerURL(brokerUrl); return activeMQConnectionFactory; } @Bean public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() { DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory(); factory.setConnectionFactory(activeMQConnectionFactory()); factory.setConcurrency("3-10"); return factory; } @Bean public Receiver receiver() { return new Receiver(); }}

（5）TestCtrl.java

package com.example.springbootactivemq.test;import com.example.springbootactivemq.jms.Sender;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map;/** * Created by yan on 2017/8/2. */@RestController@RequestMapping( value = "/test", headers = "Accept=application/json", produces = "application/json;charset=utf-8")public class TestCtrl { @Autowired private Sender sender; @Value("${queue.destination}") private String destination; @RequestMapping( value = "/say/{msg}/to/{name}", method = RequestMethod.GET ) public Map<String, Object> say(@PathVariable String msg, @PathVariable String name){ Map<String, Object> map = new HashMap<>(); map.put("msg", msg); map.put("name", name); sender.send(destination, msg); return map; }}

（6）application.properties

spring.activemq.broker-url=failover:(tcp://192.168.3.10:61616,tcp://192.168.3.11:61616,tcp://192.168.3.12:61616)spring.activemq.in-memory=truespring.activemq.pool.enabled=falsespring.activemq.user=adminspring.activemq.password=adminqueue.destination=test.queuequeue.concurrency=3-10
