介绍 Active MQ是个消息队列管理器,用于通讯的中间件。现在由我来给大家介绍一下如何使用ActiveMQ测试小程序。
修改bin目录下activemq.bat
在最后一行加入
set ACTIVEMQ_OPTS=-Xms1G -Xmx1G
保存后执行该bat文件
新建maven项目
pom文件中加入依赖
<dependencies> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-all</artifactId> <!--我的mq版本为5.9.0--> <version>5.9.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-broker --> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-broker</artifactId> <version>5.10.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-client --> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-client</artifactId> <version>5.14.0</version> </dependency> </dependencies>
发送端程序
import org.apache.activemq.ActiveMQConnection;import org.apache.activemq. ActiveMQConnectionFactory;import javax.jms.*;public class Send { // private static final int SEND_NUMBER = 10; public static void main(String[] args){ //ConnectionFactory:连接工厂,JMS用它创建连接 ConnectionFactory connectionFactory; //Connection:JMS客户端到JMS Provider的连接 Connection connection = null; //Session:一个发送或接收消息的线程 Session session; //Destination:消息的目的地;消息的接收者 Destination destination; //MessageProducer:消息发送者 MessageProducer producer; //TextMessage message; //构造ConnectionFactory实例对象,此处采用ActiveMQ的实现jar connectionFactory = new ActiveMQConnectionFactory( ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616" ); try{ //构造从工厂得到连接对象 connection = connectionFactory.createConnection(); //启动 connection.start(); //获取操作连接 session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE); //获取session注意参数值test是一个服务器的queue,须在ActiveMQ的console配置 destination = session.createQueue("test"); //得到发送者 producer = session.createProducer(destination); //设置不持久化,实际情况请根据项目决定 producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); //构造消息,这里写死了,项目就是参数,或者方法获取 sendMessage(session,producer); session.commit(); }catch (Exception e){ e.printStackTrace(); }finally { try { if(null != connection) connection.close(); }catch (Throwable ignore){} } } public static void sendMessage(Session session, MessageProducer producer) throws Exception{ for (int i = 1; i <= 100000; i++){ TextMessage message = session.createTextMessage("今日天气asda" + i);//发送消息到目的地 System.out.println("发送:"+message.getText()); producer.send(message); } } }接收端程序
import org.apache.activemq.ActiveMQConnection;import org.apache.activemq. ActiveMQConnectionFactory;import javax.jms.*;public class revice { public static void main(String[] args) { ConnectionFactory connectionFactory; Connection connection = null; Session session; Destination destination; //接收者-消费者 MessageConsumer messageConsumer; connectionFactory = new ActiveMQConnectionFactory( ActiveMQConnectionFactory.DEFAULT_USER, ActiveMQConnectionFactory.DEFAULT_PASSWORD, "tcp://localhost:61616"); try{ connection = connectionFactory.createConnection(); connection.start(); session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE); destination = session.createQueue("test"); messageConsumer = session.createConsumer(destination); while(true){ TextMessage message = (TextMessage) messageConsumer.receive(1000); if(null != message){ System.out.println("收到:"+message.getText()); }else{ break; } message.acknowledge(); } }catch(Exception ex){ ex.printStackTrace(); }finally{ try{ if(null != connection){ connection.close(); } }catch(Throwable ig){ } } } }相关推荐:
