五 ActiveMQ的Broker

1 是什麼

• 相當于一個ActiveMQ伺服器執行個體
• Broker其實就是實作了用代碼的形式啟動ActiveMQ将MQ嵌入到Java代碼中，以便随用随啟，達到了節約資源的目的，同時也保證了可靠性。

2 嵌入式Broker

• 用ActiveMQ Broker作單獨立的消息服多器來杓建JAVA應用。
• ActiveMQ也支援在vm中通信基于嵌入式的broker,能夠無縫的內建其它java應用

2.1 代碼

• pom.xml

<dependencies>
    <dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-all</artifactId>
      <version>5.15.10</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>2.10.0</version>
    </dependency>
</dependencies>
           

• BrokerServer

import org.apache.activemq.broker.Broker;
import org.apache.activemq.broker.BrokerService;

public class ActiveBrokerServer {

    public static void main(String[] args) throws Exception {
        //activeMQ也支援在VM中通信給予嵌入式的broker
        BrokerService brokerService = new BrokerService() ;
        brokerService.setUseJmx(true);
        //這相當與在本地啟動了一個activeMQ服務，端口：61616
        brokerService.addConnector("tcp://localhost:61616") ;
        brokerService.start();
    }
}
