如何在Apache Tomee下配置ActiveMQ內存設置？

Question

我在Apache TomEE下有一個嵌入式ActiveMQ。 TomEE在名為tomee.xml的文件中配置JMS，在我的例子中，它是這樣配置的

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

現在，我想指定自定義內存設置，這在activemq.xml文件中完成。 如果我添加，TomEE可以使用Spring XBeans加載activemq.xml配置，就像這樣（我認為）

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

請參見http://tomee.apache.org/jms-resources-and-mdb-container.html

那正確嗎？

我已經將5個罐子添加到了tomee的lib路徑中，就像上面鏈接中所示。

然后，我有一個像這樣的activemq.xml

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

        <systemUsage>
            <systemUsage>
                <memoryUsage>

                </memoryUsage>

                </storeUsage>
                <tempUsage>
                    <tempUsage limit="50 gb" />
                </tempUsage>
            </systemUsage>
        </systemUsage>

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

但很明顯，我在這里做錯了，因為JMS沒有啟動並返回錯誤信息

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

我在這里想念的是什么？

更新 - 然后更多信息

然后我添加了activemq.xml文件的絕對路徑，因為我無法讓它在eclipse中工作（我知道，這可能更像是eclipse的錯誤）

然后我改變了一些無效的XML，例如

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

並替換為網站的默認值

<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>

從maven存儲庫添加kahadb並從activemq-all切換到activemq-spring並將bean定義為activemq.xml之后

    </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>

終於......我收到了一個新的錯誤

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]

一些谷歌之后，一些解決方案似乎與activemq無法加載XML無關（有意義，因為XML是最新技術，發明於96年，差不多20年前）

我脫掉了頭發。

Answer 1

我認為您的傳輸連接器配置應如下所示：

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

請參閱連接器的文檔 。
