activemq安装使用教程

一、下载安装

下载地址：http://activemq.apache.org/activemq-5158-release.html

然后解压即可，apache的东西解压后就可以使用了。

二、启动

在安装目录的bin目录下：

activemq start

就可以启动了。

 访问localhost:8161就可以访问

 如果你想修改用户名和密码的话，在conf/jetty-realm.properties中修改即可。

然后重启就可以。

三、demo

启动activemq 中的 demo

activemq start xbean:file:../examples/conf/activemq-demo.xml

 访问：

http://localhost:8161/demo/

然后就可以收发消息了。 

 四、自己使用

介绍web项目中spring集成activemq

      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-all</artifactId>
      <version>5.15.0</version>
    </dependency>

    <dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-spring</artifactId>
