activemq 數(shù)據(jù)存儲(chǔ)

1、jdbcPersistenceAdapter數(shù)據(jù)庫(kù)存儲(chǔ)

<persistenceAdapter>

   <jdbcPersistenceAdapter dataSource="#mysql-ds" createTablesOnStartup="true"/>

</persistenceAdapter>

注:紅色標(biāo)記的地方,第一次啟動(dòng)時(shí)建議設(shè)置成true,會(huì)自動(dòng)生成 activemq_msgs/activemq_lock/activemq_acks三張表,同時(shí)需要注意,不同的activemq版本,表結(jié)構(gòu)會(huì)有所區(qū)別.表生成之后,必須將其設(shè)置成false.

<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/activemq?relaxAutoCommit=true"/>

    <property name="username" value="root"/>

    <property name="password" value="root"/>

    <property name="maxTotal" value="200"/>

    <property name="poolPreparedStatements" value="true"/>

</bean>

注:紅色標(biāo)記的地方,是針對(duì)不同的dbcp版本而言的.如果是版本1.*,則是org.apache.commons.dbcp.BasicDataSource

更多參數(shù)設(shè)置請(qǐng)參考:http://blog.csdn.net/fairyhawk/article/details/7565391

2、memoryPersistenceAdapter 內(nèi)存存儲(chǔ)

<persistenceAdapter>

   <memoryPersistenceAdapter/>

</persistenceAdapter>

或者將persistent=false。

3、kahaDB文件存儲(chǔ)

<persistenceAdapter>

  <kahaDB directory="${activemq.data}/kahadb"/>

</persistenceAdapter>

4、journalPersistenceAdapter文件存儲(chǔ)

<persistenceAdapter>
    <journaledJDBC dataDirectory="${activemq.base}/data" dataSource="#postgres-ds"/>
</persistenceAdapter>

適用場(chǎng)景:對(duì)于集群的broker用JDBC的消息和日志存儲(chǔ),可以有效的避免數(shù)據(jù)丟失.

5、mKahaDB文件存儲(chǔ)

<persistenceAdapter>

  <mKahaDB directory="${activemq.data}/kahadb"/>

</persistenceAdapter>

6、replicatedLevelDB文件存儲(chǔ)

<persistenceAdapter>

   <replicatedLevelDB

      directory="${activemq.data}"

      replicas="2"

      bind="tcp://0.0.0.0:61619"

      zkAddress="127.0.0.1:2181"

      zkPassword="password"

      zkPath="/activemq/leveldb-stores"

      />

</persistenceAdapter>

7、levelDB文件存儲(chǔ)

<persistenceAdapter>

  <levelDB directory="${activemq.data}/leveldb"/>

</persistenceAdapter>
