学习：SpringBoot整合ActiveMQ
SpringBoot整合ActiveMQ
ActiveMQ是MQ产品中的元老级产品，早期标准MQ产品之一，在AMQP协议没有出现之前，占据了消息中间件市场的绝大部分份额，后期因为AMQP系列产品的出现，迅速走弱，目前仅在一些线上运行的产品中出现，新产品开发较少采用。
安装
windows版安装包下载地址：https://activemq.apache.org/components/classic/download/
下载的安装包是解压缩就能使用的zip文件，解压缩完毕后会得到如下文件
启动服务器
CMD
activemq.bat 运行bin目录下的win32或win64目录下的activemq.bat命令即可，根据自己的操作系统选择即可，默认对外服务端口61616。
访问web管理服务
ActiveMQ启动后会启动一个Web控制台服务，可以通过该服务管理ActiveMQ。
CMD
http://127.0.0.1:8161/ web管理服务默认端口8161，访问后可以打开ActiveMQ的管理界面，如下：
首先输入访问用户名和密码，初始化用户名和密码相同，均为：admin，成功登录后进入管理后台界面，如下：
看到上述界面视为启动ActiveMQ服务成功。
启动失败
在ActiveMQ启动时要占用多个端口，以下为正常启动信息：

请按任意键继续. . .整合
做了这么多springboot整合第三方技术，已经摸到门路了，加坐标，做配置，调接口，直接开工
步骤①：导入springboot整合ActiveMQ的starter
xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-activemq</artifactId>
</dependency>步骤②：配置ActiveMQ的服务器地址
yaml
spring:
activemq:
broker-url: tcp://localhost:61616步骤③：使用JmsMessagingTemplate操作ActiveMQ
java
@Service
public class MessageServiceActivemqImpl implements MessageService {
@Autowired
private JmsMessagingTemplate messagingTemplate;
@Override
public void sendMessage(String id) {
System.out.println("待发送短信的订单已纳入处理队列，id："+id);
messagingTemplate.convertAndSend("order.queue.id",id);
}
@Override
public String doMessage() {
String id = messagingTemplate.receiveAndConvert("order.queue.id",String.class);
System.out.println("已完成短信发送业务，id："+id);
return id;
}
} 发送消息需要先将消息的类型转换成字符串，然后再发送，所以是convertAndSend，定义消息发送的位置，和具体的消息内容，此处使用id作为消息内容。
接收消息需要先将消息接收到，然后再转换成指定的数据类型，所以是receiveAndConvert，接收消息除了提供读取的位置，还要给出转换后的数据的具体类型。
步骤④：使用消息监听器在服务器启动后，监听指定位置，当消息出现后，立即消费消息
java
@Component
public class MessageListener {
@JmsListener(destination = "order.queue.id")
@SendTo("order.other.queue.id")
public String receive(String id){
System.out.println("已完成短信发送业务，id："+id);
return "new:"+id;
}
} 使用注解@JmsListener定义当前方法监听ActiveMQ中指定名称的消息队列。
如果当前消息队列处理完还需要继续向下传递当前消息到另一个队列中使用注解@SendTo即可，这样即可构造连续执行的顺序消息队列。
步骤⑤：切换消息模型由点对点模型到发布订阅模型，修改jms配置即可
yaml
spring:
activemq:
broker-url: tcp://localhost:61616
jms:
pub-sub-domain: true pub-sub-domain默认值为false，即点对点模型，修改为true后就是发布订阅模型。
总结
- springboot整合ActiveMQ提供了JmsMessagingTemplate对象作为客户端操作消息队列
- 操作ActiveMQ需要配置ActiveMQ服务器地址，默认端口61616
- 企业开发时通常使用监听器来处理消息队列中的消息，设置监听器使用注解@JmsListener
- 配置jms的pub-sub-domain属性可以在点对点模型和发布订阅模型间切换消息模型
