ActiveMQ 入门使用实例

1.下载ActiveMQ

去官方网站下载：http://activemq.apache.org/download-archives.html

2.运行ActiveMQ

解压缩apache-activemq-5.9.0-bin.zip，然后双击apache-activemq-5.9.0\bin\activemq.bat运行ActiveMQ程序。

3.在Eclipse 创建项目并运行

如果是使用 Maven 项目，则在pom.xml 中配置

<dependency>
  <groupId>org.apache.activemq</groupId>
  <artifactId>activemq-all</artifactId>
  <version>5.9.0</version>
</dependency>

或者 直接创建项目，导入 activemq-all-5.9.0.jar ，以及其日志依赖包

4.创建一个消息队列

                message.setLong("count", date.getTime());

                producer.send(message);
                System.out.println("--发送消息："+date);

            session.close();

        catch (Exception e)

运行这两个方法，则可以在控制台看到  consumer 输出了 producter 产生的消息
