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：
@Service
public 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.
*/
@Configuration
public class SenderConfig {
@Value("${spring.activemq.broker-url}")
private String brokerUrl;
@Bean
public ActiveMQConnectionFactory activeMQConnectionFactory() {
ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
activeMQConnectionFactory.setBrokerURL(brokerUrl);
return activeMQConnectionFactory;
}
@Bean
public CachingConnectionFactory cachingConnectionFactory() {
return new CachingConnectionFactory(activeMQConnectionFactory());
}
@Bean
public JmsTemplate jmsTemplate() {
return new JmsTemplate(cachingConnectionFactory());
}
@Bean
public Sender sender() {
return new Sender();
}
}（2）Sender.java
package com.example.springbootactivemq.jms;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
import javax.jms.TextMessage;
/**
* Created by yan on 2017/8/3.
*/
public class Sender {
@Autowired
private JmsTemplate jmsTemplate;
public void send(final String destination, final String message){
this.jmsTemplate.convertAndSend(destination, message);
}
}（3）Receiver.java
package com.example.springbootactivemq.jms; import org.springframework.jms.annotation.JmsListener; import org.springframework.jms.listener.SessionAwareMessageListener; import org.springframework.jms.support.JmsUtils; import javax.jms.JMSException; import javax.jms.MessageProducer; import javax.jms.Session; import javax.jms.TextMessage; /** * Created by yan on 2017/8/3. */ public class Receiver implements SessionAwareMessageListener{ @JmsListener(destination = "${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
@EnableJms
public 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 say(@PathVariable String msg, @PathVariable String name){
Map 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=true spring.activemq.pool.enabled=false spring.activemq.user=admin spring.activemq.password=admin queue.destination=test.queue queue.concurrency=3-10
