ActiveMQ实例1--简单的发送和接收消息

一、环境准备

1,官网http://activemq.apache.org/下载最新版本的ActiveMQ,并解压

2,打开对应的目录,在Mac环境下,一般可以运行命令:

  cd /Users/***/Downloads/apache-activemq-***/bin/macosx  

  ./activemq start

3,启动成功后,登录http://localhose:8161/admin/,登陆账号和密码都为admin,创建一个queue名为jyQueue。

 

二、创建Eclipse项目

1,新建项目,并导入对应的jar文件如下图所示

 

2,Sender.java和Receiver.java

20         Connection connection = null;

42             destination = session.createQueue("jyQueue");
43             // 得到消息生成者【发送者】
44             producer = session.createProducer(destination);
45             // 设置不持久化,此处学习,实际根据项目决定
46             producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
47             // 构造消息,此处写死,项目就是参数,或者方法获取
48             sendMessage(session, producer);
49             session.commit();
50         } catch (Exception e) {

56             } catch (Throwable ignore) {

58         }
59     }

3,先后运行Sender.java和Receiver.java
