问题一：

  activemq:
    pool:
      enabled: true

开启连接池，启动项目会报错，提示JmsMessagingTemplate无法注入，只要加上依赖即可。

 <!--springboot2.X 要开启activemq pool必须引入此连接池依赖-->
        <dependency>
            <groupId>org.messaginghub</groupId>
            <artifactId>pooled-jms</artifactId>
        </dependency>

因为JmsMessagingTemplate本身依赖连接工厂，启用连接池后就会依赖连接池工厂，因为版本的原因，如果没有正确的引入连接池依赖，那么项目启动肯定会报错：JmsMessagingTemplate无法注入。

因为你不引入，IDEA会标红显示无这个类（JmsPoolConnectionFactory）

package org.springframework.boot.autoconfigure.jms.artemis;
 
import javax.jms.ConnectionFactory;
 
import org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory;
import org.apache.commons.pool2.PooledObject;
 
 
@Configuration(proxyBeanMethods = false)
@ConditionalOnMissingBean(ConnectionFactory.class)
class ArtemisConnectionFactoryConfiguration {
 
	@Configuration(proxyBeanMethods = false)
	@ConditionalOnClass({ JmsPoolConnectionFactory.class, PooledObject.class })
	static class PooledConnectionFactoryConfiguration {
 
		@Bean(destroyMethod = "stop")
		@ConditionalOnProperty(prefix = "spring.artemis.pool", name = "enabled", havingValue = "true",
				matchIfMissing = false)
		JmsPoolConnectionFactory pooledJmsConnectionFactory(ListableBeanFactory beanFactory,
				ArtemisProperties properties) {
			ActiveMQConnectionFactory connectionFactory = new ArtemisConnectionFactoryFactory(beanFactory, properties)
					.createConnectionFactory(ActiveMQConnectionFactory.class);
			return new JmsPoolConnectionFactoryFactory(properties.getPool())
					.createPooledConnectionFactory(connectionFactory);
		}
 
	}
 
}

问题二：

控制台一直打印，不断重复，会很浪费空间，所以取消掉此类的打印日志

[20:09:59:585] [DEBUG] - org.apache.activemq.ActiveMQSession.commit(ActiveMQSession.java:580) - ID:DESKTOP-98F4QUU-56334-1582027509219-1:1:1 Transaction Commit :null
[20:10:00:594] [DEBUG] - org.apache.activemq.ActiveMQSession.commit(ActiveMQSession.java:580) - ID:DESKTOP-98F4QUU-56334-1582027509219-1:1:1 Transaction Commit :null

解决办法一：治标不治本

使用log4j2的话，使用以下配置就行，其他无关问题配置省略空间，就不写了

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="ERROR" monitorInterval="30">   
    <loggers>
        <!--过滤掉spring和mybatis的一些无用的DEBUG信息和打印事务为空的日志-->
        <logger name="org.springframework" level="INFO"></logger>
        <logger name="org.mybatis" level="INFO"></logger>
        <logger name="org.apache.activemq.ActiveMQSession" level="ERROR"></logger>
    </loggers>
</configuration>

解决办法二：手动确认消息

1.添加以下配置，参考https://blog.csdn.net/p_programmer/article/details/88384138

    @Bean
    public DefaultJmsListenerContainerFactory myFactory(ConnectionFactory connectionFactory, DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        factory.setSessionTransacted(false);
        factory.setSessionAcknowledgeMode(4);
        return factory;
    }

2.在消费者处，手动确认，以及指定工厂，这里的案例可以看·我写的SpringBoot2.X 使用ActiveMQ实战项目之实现登陆日志保存

//指定自定义的工厂    
@JmsListener(destination = "login-info",containerFactory = "myFactory")
    public void handle(Message message) {
        if (message instanceof ActiveMQObjectMessage) {
            ActiveMQObjectMessage activeMQObjectMessage = (ActiveMQObjectMessage) message;
            try {
                Loginfo loginfo = (Loginfo) activeMQObjectMessage.getObject();
                loginfoService.save(loginfo);
                //手动确认消息
                activeMQObjectMessage.acknowledge();
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    }
