1.下载ActiveMQ
去官方网站下载:http://activemq.apache.org/
我下载的时候是 ActiveMQ 5.14.0 Release版
2.运行ActiveMQ
解压缩apache-activemq-5.14.0-bin.zip,然后双击apache-activemq-5.14.0-bin\apache-activemq-5.14.0\bin\win64\activemq.bat运行ActiveMQ程序。
启动ActiveMQ以后,登陆:http://localhost:8161/admin/,创建一个Queue,命名为FirstQueue。
3.创建Eclipse项目并运行
创建java project:ActiveMQ-5.14,新建lib文件夹
打开apache-activemq-5.14.0-bin\apache-activemq-5.14.0\lib目录
拷贝如下6个jar包:
activemq-broker-5.14.0.jar
activemq-client-5.14.0.jar
activemq-all-5.14.0.jar
geronimo-j2ee-management_1.1_spec-1.0.1.jar
geronimo-jms_1.1_spec-1.1.1.jar
slf4j-api-1.7.13.jar
这6个jar文件到lib文件夹中,并Build Path->Add to Build Path
结构如图:
4、示例代码
Sender.java :
- package test;
- import javax.jms.Connection;
- import javax.jms.ConnectionFactory;
- import javax.jms.DeliveryMode;
- import javax.jms.Destination;
- import javax.jms.MessageProducer;
- import javax.jms.Session;
- import javax.jms.TextMessage;
- import org.apache.activemq.ActiveMQConnection;
- import org.apache.activemq.ActiveMQConnectionFactory;
- publicclassSender{
- privatestaticfinalint SEND_NUMBER =5;
- publicstaticvoid main(String[] args){
- ConnectionFactory connectionFactory;// ConnectionFactory--连接工厂,JMS用它创建连接
- // Provider 的连接
- Connection connection =null;// Connection :JMS 客户端到JMS
- Session session;// Session: 一个发送或接收消息的线程
- Destination destination;// Destination :消息的目的地;消息发送给谁.
- MessageProducer producer;// MessageProducer:消息发送者
- // 构造ConnectionFactory实例对象,此处采用ActiveMq的实现jar
- connectionFactory =newActiveMQConnectionFactory(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xingbo.xu-queue是一个服务器的queue,须在在ActiveMq的console配置
- destination = session.createQueue("FirstQueue");
- // 得到消息生成者【发送者】
- producer = session.createProducer(destination);
- // 设置不持久化,此处学习,实际根据项目决定
- producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
- // 构造消息,此处写死,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){
- }
- }
- }
- publicstaticvoid sendMessage(Session session,MessageProducer producer)throwsException{
- for(int i =1; i <= SEND_NUMBER; i++){
- TextMessage message = session.createTextMessage("ActiveMq 发送的消息"+ i);
- // 发送消息到目的地方
- System.out.println("发送消息:"+"ActiveMq 发送的消息"+ i);
- producer.send(message);
- }
- }
- }
Receiver.java :
- package test;
- import javax.jms.Connection;
- import javax.jms.ConnectionFactory;
- import javax.jms.Destination;
- import javax.jms.MessageConsumer;
- import javax.jms.Session;
- import javax.jms.TextMessage;
- import org.apache.activemq.ActiveMQConnection;
- import org.apache.activemq.ActiveMQConnectionFactory;
- public class Receiver {
- 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;消息发送给谁.
- Destination destination;
- // 消费者,消息接收者
- MessageConsumer consumer;
- 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.FALSE,
- Session.AUTO_ACKNOWLEDGE);
- // 获取session注意参数值xingbo.xu-queue是一个服务器的queue,须在在ActiveMq的console配置
- destination = session.createQueue("FirstQueue");
- consumer = session.createConsumer(destination);
- while (true) {
- // 设置接收者接收消息的时间,为了便于测试,这里谁定为100s
- TextMessage message = (TextMessage) consumer.receive(500000);
- if (null != message) {
- System.out.println("收到消息" + message.getText());
- } else {
- break;
- }
- }
- } catch (Exception e) {
- e.printStackTrace();
- } finally {
- try {
- if (null != connection)
- connection.close();
- } catch (Throwable ignore) {
- }
- }
- }
- }
5.测试过程
先运行:Receiver.java
再运行:Sender.java
可以看到结果
Sender运行后:
- 发送消息:ActiveMq发送的消息1
- 发送消息:ActiveMq发送的消息2
- 发送消息:ActiveMq发送的消息3
- 发送消息:ActiveMq发送的消息4
- 发送消息:ActiveMq发送的消息5
Receiver运行后:
- 收到消息ActiveMq发送的消息1
- 收到消息ActiveMq发送的消息2
- 收到消息ActiveMq发送的消息3
- 收到消息ActiveMq发送的消息4
- 收到消息ActiveMq发送的消息5
