ActionMQ5.8.0 JMS实例 手把手详细图解

Posted 2020-10-26 牵着妞去散步

ActionMQ 是开源的JMS实现

1.下载ActiveMQ

去官方网站下载：http://activemq.apache.org/

2.运行ActiveMQ

解压缩apache-activemq-5.5.1-bin.zip，然后双击apache-activemq-5.8.0\bin\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。如下图

目录结构如下：

运行在网页中，它会让你登录用户方可进入，默认的用户名和密码是admin，

3 . 测试
ActiveMQ默认使用的TCP连接端口是61616,通过查看该端口的信息可以测试ActiveMQ是否成功启动
window环境运行  netstat -an|find "61616"

Class源代码中可以看到

4.创建Eclipse JAVA项目并运行

创建project：ActiveMQ-5.8，并导入apache-activemq-5.8.0\lib目录下需要用到的jar文件，项目结构如下图所示：

若找不到相应的包，使用以下连接下载也行 http://repo1.maven.org/maven2/org/apache/activemq/activemq-rar/

            consumer = session.createConsumer(destination);  
            while (true) {

4.注意事项

先启动apache-activemq-5.8.0\bin\activemq.bat运行ActiveMQ程序。在运行main方法，否则回报连接失败的错误，如下

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

5.测试过程

1、先运行Sender，输出以下信息，若先运行Receiver则无输出

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

2、运行Receiver

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
