SpringBoot2.0整合ActiveMQ

【1】pom文件

添加ActiveMQ依赖：

<!--整合ActiveMQ-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-pool</artifactId>
</dependency>

---

【2】yml配置

yml配置文件如下：

spring:
    activemq:
      user: root
      password: 123456
      broker-url: tcp://127.0.0.1:61616
      pool:
        enabled: true
        max-connections: 50
      packages:
        trust-all: true

---

【3】生产者消费者队列

主程序类配置如下：

@SpringBootApplication
@EnableJms //ActiveMQ
public class HhProvinceApplication {

    public static void main(String[] args) {
        SpringApplication.run(HhProvinceApplication.class, args);
    }
}

---

MyActiveMQConfig如下：

@Configuration
public class MyActiveMQConfig {

    @Bean
    public Queue logQueue() {
        return new ActiveMQQueue("app.log");
    }
}

---

生产者示例：

@Service
public class SysVisitLogServiceImpl implements ISysVisitLogService {

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

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue logQueue;


    /* 日志插入 */
    public void insertVisitLog(SysVisitLog sysVisitLog) {
        log.debug("insertVisitLog :收到请求，开始调用队列插入访问日志--"+sysVisitLog);
        jmsMessagingTemplate.convertAndSend(logQueue, sysVisitLog);
    }
}

---

消费者示例：

@Service
public class ConsumerListener {

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

    @Autowired
    SysVisitLogMapper visitLogMapper;

    @JmsListener(destination="app.log")
    @Transactional(rollbackFor={Exception.class})
    public void insertVisitLog(SysVisitLog sysVisitLog){
        int i = visitLogMapper.insertSelective(sysVisitLog);
        log.info("消费者插入日志成功 i:"+i+"--sysVisitLog : "+sysVisitLog);
    }
}

---

【4】以前SSM下使用ActiveMQ

以前在SSM(SpringMVC Spring MyBatis)下主要使用xml对ActiveMQ进行配置，代码中生产者和消费者同样使用注解。

ActiveMQ xml配置如下：

  <!--这个是队列目的地，点对点的-->
    <bean id="InsertVisitLogQueue" class="org.apache.activemq.command.ActiveMQQueue">
         <constructor-arg>
             <value>InsertVisitLogQueue</value>
         </constructor-arg>
    </bean> 

    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">    
        <property name="connectionFactory">    
            <bean class="org.apache.activemq.ActiveMQConnectionFactory">    
            <property name="brokerURL" value="tcp://127.0.0.1:61616" />
            <property name="userName" value="root" />
            <property name="password" value="123456" />
            <property name="useAsyncSend" value="true" /> 
            <property name="trustAllPackages" value="true"/>
            </bean>    
        </property> 
    </bean>

    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="receiveTimeout" value="2000" />
    </bean>

    <!-- 支持@JmsListener自动启动监听器 -->
    <jms:annotation-driven/>

    <bean id="jmsListenerContainerFactory"  class="org.springframework.jms.config.DefaultJmsListenerContainerFactory">
         <property name="connectionFactory" ref="connectionFactory"/>
    </bean>

对比SpringBoot2.0，可以发现简化了很多配置。

生产者示例：

@Service
public class SysVisitLogServiceImpl implements ISysVisitLogService {

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

    @Autowired
    private JmsTemplate jmsTemplate;

    @Qualifier("InsertVisitLogQueue")
    @Autowired
    private Destination destinationInsertVisitLogQueue;

    /* 插入tb_sys_visit_log */
    @Override
    public void insertVisitLog(SysVisitModel sysVisitModel) {
        log.debug("insertVisitLog :收到请求，开始调用队列插入访问日志--"+sysVisitModel);
        new Thread(new Runnable(){
            @Override
            public void run() {
                jmsTemplate.send(destinationInsertVisitLogQueue, new MessageCreator() {
                    @Override
                    public Message createMessage(Session session) throws JMSException {
                        ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session.createObjectMessage(); 
                        msg.setObject(sysVisitModel);
                        /* 一分钟后插入访问日志 */
                        long delay = 60 * 1000;
                        msg.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, delay);
                        return msg;   
                    } 
                }); 

            }}).start();
    }

}

消费者示例：

@Service
public class ConsumerListener {

    @JmsListener(destination="InsertVisitLogQueue",concurrency="10-20")
    @Transactional(rollbackFor={Exception.class})
    public void insertVisitLog(SysVisitModel sysVisitModel){
        log.info("消费者获取到的sysVisitModel ： "+sysVisitModel+Thread.currentThread().getName());
        //...
        }
}
