如何在Apache Tomee下配置ActiveMQ内存设置?

标签: java activemq tomee

我在Apache TomEE下有一个嵌入式ActiveMQ。 TomEE在一个名为tomee.xml的文件中配置JMS,在我的例子中,它配置如下

<Resource id="Default JMS Resource Adapter" type="ActiveMQResourceAdapter">
    BrokerXmlConfig = broker:(tcp://localhost:61616)?persistent=true
    ServerUrl = tcp://localhost:61616
    DataSource = MyDataSource
</Resource>

现在,我想指定自定义内存设置,该设置在activemq.xml文件中完成。如果我添加,TomEE可以使用Spring XBeans加载activemq.xml配置,就像这样(我认为)

<Resource id="Default JMS Resource Adapter" type="ActiveMQResourceAdapter">
    BrokerXmlConfig = xbean:file:conf/activemq.xml
    ServerUrl = tcp://localhost:61616
    DataSource = MyDataSource
</Resource>

请参阅http://tomee.apache.org/jms-resources-and-mdb-container.html

是吗?

我已将5个罐子添加到tomee的lib路径中,如上面的链接所示。

然后,我有一个像这样的activemq.xml

    <!-- Allows us to use system properties as variables in this configuration file -->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

                    <pendingQueuePolicy>
                        <vmQueueCursor />
                    </pendingQueuePolicy>
                </policyEntries>
            </policyMap>
        </destinationPolicy>

        <systemUsage>
            <systemUsage>
                <memoryUsage>
                    <memoryUsage limit="128 mb" />
                </memoryUsage>
                <storeUsage>
                    <storeUsage limit="100 gb" />
                </storeUsage>
                <tempUsage>
                    <tempUsage limit="50 gb" />
                </tempUsage>
            </systemUsage>
        </systemUsage>

        <transportConnectors>
            <transportConnector name="anythingHere" uri="broker:(tcp://localhost:61616)?persistent=true"/>
        </transportConnectors>
    </broker>
</beans>

但显然,我在这里做错了,因为JMS没有启动并返回错误消息,如

SEVERE: Failed to connect to broker [tcp://localhost:61616]: Could not connect to
broker URL: tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused
javax.jms.JMSException: Could not connect to broker URL: tcp://localhost:61616. Reason:
java.net.ConnectException: Connection refused

我在这里错过了什么?

更新 - 更多信息

然后我添加了activemq.xml文件的绝对路径,因为我无法让它在eclipse中工作(我知道,这可能更像是eclipse的错误)

然后我改变了一些无效的XML,例如

<!--             <destinationPolicy> -->
<!--                 <policyMap> -->
<!--                     <policyEntries> -->
<!--                         <policyEntry queue=">" producerFlowControl="false" prioritizedMessages="true" useCache="false" expireMessagesPeriod="0" queuePrefetch="1" /> -->
<!--                         <pendingQueuePolicy> -->
<!--                             <vmQueueCursor /> -->
<!--                         </pendingQueuePolicy> -->
<!--                     </policyEntries> -->
<!--                 </policyMap> -->
<!--             </destinationPolicy> -->

并替换为网站的默认

<destinationPolicy>
        <policyMap>
          <policyEntries>
            <policyEntry topic=">" producerFlowControl="true">
                <!-- The constantPendingMessageLimitStrategy is used to prevent
                     slow topic consumers to block producers and affect other consumers
                     by limiting the number of messages that are retained
                     For more information, see:

                     http://activemq.apache.org/slow-consumer-handling.html

                -->
              <pendingMessageLimitStrategy>
                <constantPendingMessageLimitStrategy limit="1000"/>
              </pendingMessageLimitStrategy>
            </policyEntry>
            <policyEntry queue=">" producerFlowControl="true" memoryLimit="1mb">
              <!-- Use VM cursor for better latency
                   For more information, see:

                   http://activemq.apache.org/message-cursors.html

              <pendingQueuePolicy>
                <vmQueueCursor/>
              </pendingQueuePolicy>
              -->
            </policyEntry>
          </policyEntries>
        </policyMap>
    </destinationPolicy>

从maven存储库添加kahadb并从activemq-all切换到activemq-spring并将bean定义为activemq.xml

    </broker>

    <bean id="oracle-ds" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
        <property name="url" value="jdbc:oracle:thin:@localhost:1521:XE"/>
        <property name="username" value="xxx"/>
        <property name="password" value="xxx"/>
        <property name="poolPreparedStatements" value="true"/>
      </bean>

</beans>

终于......我收到了一个新错误

SEVERE: Failed to load: URL [file:/home/leoks/EclipseIndigo/workspace2/Servers     /TomEE1.6.0-STABLE-config/activemq.xml], reason: Error creating bean with name  'org.apache.activemq.xbean.XBeanBrokerService#0' defined in URL [file:/home/leoks /EclipseIndigo/workspace2/Servers/TomEE1.6.0-STABLE-config/activemq.xml]: Invocation of init method failed; nested exception is java.io.IOException: Transport Connector could not be registered in JMX: Transport scheme NOT recognized: [broker]

在一些谷歌之后,一些解决方案似乎与activemq无法加载XML无关(有意义,因为XML是最新技术,发明于96年,差不多20年前)

我脱掉了头发。

答案 0 :(得分:3)

我认为传输连接器配置应该如下所示:

<transportConnectors>
    <transportConnector name="tcp" uri="tcp://0.0.0.0:61616"/>
</transportConnectors>

请参阅documentation了解连接器。
