ActiveMQ 消息持久化到Mysql数据库

一、下载ActiveMQ

版本：ActiveMQ 5.15.3 Release

地址：http://activemq.apache.org/download.html

二、运行ActiveMQ

1、解压apache-activemq-5.15.3-bin.zip

2、执行inwin64activemq.bat脚本即可启动AMQ

三、修改配置文件持久化到Mysql数据库

文件路径：confactivemq.xml

<!--
    Configure message persistence for the broker. The default persistence
    mechanism is the KahaDB store (identified by the kahaDB tag).
    For more information, see:

    http://activemq.apache.org/persistence.html
-->
<persistenceAdapter>
    <!--<kahaDB directory="${activemq.data}/kahadb"/>-->
    <jdbcPersistenceAdapter dataSource="#mysql-ds"/>
</persistenceAdapter>

<bean id="mysql-ds" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/db_activemq?relaxAutoCommit=true"/>
    <property name="username" value="root"/>
    <property name="password" value="root"/>
    <property name="poolPreparedStatements" value="true"/>
</bean>

<!--
    Enable web consoles, REST and Ajax APIs and demos
    The web consoles requires by default login, you can disable this in the jetty.xml file

    Take a look at ${ACTIVEMQ_HOME}/conf/jetty.xml for more details
-->
<import resource="jetty.xml"/>

四、引入Mysql包

复制mysql-connector-java-5.1.45.jar包到lib目录下

五、重新运行AMQ，数据库自动生成3张表

activemq_acks：用于存储订阅关系。如果是持久化Topic，订阅者和服务器的订阅关系在这个表保存

activemq_lock：在集群环境中才有用，只有一个Broker可以获得消息，称为Master Broker

activemq_msgs：用于存储消息，Queue和Topic都存储在这个表中
