ActiveMQ messaging middleware of the (three): SpringBoot ActiveMQ integration

Without further ado, on dry goods:

Integrate

  1. Establish a springboot initialization project
    slightly (this may be)
  2. pom.xml introduced the following packages:
    Note: I use is 5.15.11, so the bag is introduced to the latest 5.15.11
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-activemq</artifactId>
            <version>2.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-pool</artifactId>
            <version>5.15.11</version>
        </dependency>
  1. application.yml added as follows:
spring:
  activemq:
    # mq通信地址
    broker-url: tcp://39.96.70.45:61616
    # 是否启用内存模式(就是不安装MQ,项目启动时同时启动一个MQ实例)
    in-memory: false
    pool:
      # 是否开启连接池,使用ActiveMQ的连接池需要引入activemq-pool依赖
      # true时候会报required a bean of type 'org.springframework.jms.core.JmsMessagingTemplate' that could not be found.异常,文章最后有处理方案。
      enabled: false
      # 空闲的连接过期时间,默认为30秒
      idle-timeout: 30000
      # 连接池最大连接数
      max-connections: 10
  1. Start classes with the following comment:
    @EnableJms: a statement of support for JMS notes
@EnableJms
@SpringCloudApplication
public class DemoApplication {
	    public static void main(String[] args) {
        SpringApplication.run(DemoApplication .class, args);
    }
}
  1. Establish activeMQ configuration class ActiveMqConfig.java
package com.jifang.netty.config;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.jms.Queue;

/**
 * ActiveMq配置
 *
 * @author wangdy
 * @date 2020/2/7 15:15
 */
@Configuration
public class ActiveMqConfig {
	/**
	 * 定义存放消息的队列
	 */
	@Bean
	public Queue queue() {
		return new ActiveMQQueue("chat-queue");
	}
}
  1. Production and sending a message
package com.jifang.netty.service.impl;

import cn.hutool.json.JSONUtil;
import com.jifang.netty.enums.MsgActionTypeEnum;
import com.jifang.netty.enums.MsgTypeEnum;
import com.jifang.netty.service.MessageService;
import com.jifang.netty.service.MqMessageService;
import com.jifang.netty.utils.JsonUtil;
import com.jifang.netty.vo.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Service;

import javax.jms.Queue;

/**
 * @author wangdy
 * @date 2020/2/7 15:21
 */
@Service
public class MqMessageServiceImpl implements MqMessageService {
	@Autowired
	private Queue queue;
	@Autowired
	private JmsMessagingTemplate jmsMessagingTemplate;
	@Autowired
	private MessageService messageService;

	/**
		发送消息
	*/
	@Override
	public void sendMessage(String message) {
		// 方法1:添加消息到消息队列
		jmsMessagingTemplate.convertAndSend(queue, message);
		// 方法2:这种方式不需要手动创建queue,系统会自行创建名为testQueue的队列
		// jmsMessagingTemplate.convertAndSend("testQueue", message);
	}

	/**
		消费消息
	*/
	@Override
	@JmsListener(destination = "chat-queue")// 使用JmsListener配置消费者监听的队列,其中message是接收到的消息
	public void handleMessage(String message) {
		System.out.println("成功接收:message" + message);
	}
}

pit

The above set pool.enabled = true error will start by looking at the source code, I found that as used herein springboot 2.1.x version, the default @ConditionalOnClass ({JmsPoolConnectionFactory.class, PooledObject.class}) , the source code is as follows:
JmsPoolConnectionFactory

@Configuration
@ConditionalOnMissingBean(ConnectionFactory.class)
class ActiveMQConnectionFactoryConfiguration {

    @Configuration
    @ConditionalOnClass(CachingConnectionFactory.class)
    @ConditionalOnProperty(prefix = "spring.activemq.pool", name = "enabled", havingValue = "false", matchIfMissing = true)
    static class SimpleConnectionFactoryConfiguration {

        private final JmsProperties jmsProperties;

        private final ActiveMQProperties properties;

        private final List<ActiveMQConnectionFactoryCustomizer> connectionFactoryCustomizers;

        SimpleConnectionFactoryConfiguration(JmsProperties jmsProperties,
                ActiveMQProperties properties,
                ObjectProvider<ActiveMQConnectionFactoryCustomizer> connectionFactoryCustomizers) {
            this.jmsProperties = jmsProperties;
            this.properties = properties;
            this.connectionFactoryCustomizers = connectionFactoryCustomizers
                    .orderedStream().collect(Collectors.toList());
        }

        @Bean
        @ConditionalOnProperty(prefix = "spring.jms.cache", name = "enabled", havingValue = "true", matchIfMissing = true)
        public CachingConnectionFactory cachingJmsConnectionFactory() {
            JmsProperties.Cache cacheProperties = this.jmsProperties.getCache();
            CachingConnectionFactory connectionFactory = new CachingConnectionFactory(
                    createConnectionFactory());
            connectionFactory.setCacheConsumers(cacheProperties.isConsumers());
            connectionFactory.setCacheProducers(cacheProperties.isProducers());
            connectionFactory.setSessionCacheSize(cacheProperties.getSessionCacheSize());
            return connectionFactory;
        }

        @Bean
        @ConditionalOnProperty(prefix = "spring.jms.cache", name = "enabled", havingValue = "false")
        public ActiveMQConnectionFactory jmsConnectionFactory() {
            return createConnectionFactory();
        }

        private ActiveMQConnectionFactory createConnectionFactory() {
            return new ActiveMQConnectionFactoryFactory(this.properties,
                    this.connectionFactoryCustomizers)
                            .createConnectionFactory(ActiveMQConnectionFactory.class);
        }

    }

 // 注意:此处用的是import org.messaginghub.pooled.jms.JmsPoolConnectionFactory;
    @Configuration
    @ConditionalOnClass({ JmsPoolConnectionFactory.class, PooledObject.class })
    static class PooledConnectionFactoryConfiguration {

        @Bean(destroyMethod = "stop")
        @ConditionalOnProperty(prefix = "spring.activemq.pool", name = "enabled", havingValue = "true", matchIfMissing = false)
        public JmsPoolConnectionFactory pooledJmsConnectionFactory(
                ActiveMQProperties properties,
                ObjectProvider<ActiveMQConnectionFactoryCustomizer> factoryCustomizers) {
            ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactoryFactory(
                    properties,
                    factoryCustomizers.orderedStream().collect(Collectors.toList()))
                            .createConnectionFactory(ActiveMQConnectionFactory.class);
            return new JmsPoolConnectionFactoryFactory(properties.getPool())
                    .createPooledConnectionFactory(connectionFactory);
        }
    }
}

So Solution:
replace the original activemq-pool use: pooled-jms
Note: many places online, said springboot2.0.x not have this problem. I did fine research, interested can look at the source code.

Run the program, call the method to send a message, you can see the change queue messages, receive messages and log console print.
