Question

我有一个持久订阅ActiveMQ的JMS代理在WSO2 ESB v4.5.1和v4.7中完美运行

我正在尝试在WSO2 ESB v4.8.0（里程碑3或4）中使用它而没有成功

在启动ESB之前，主题未定义到ActiveMQ中，并且没有引用持久订阅者（ActiveMQ控制台中有0个脱机订阅者）

ESB中的JMS代理：

<proxy xmlns="http://ws.apache.org/ns/synapse" name="TestJMSProxy" transports="jms" startOnLoad="true" trace="disable">
    <target>
        <inSequence>
          <log level="full"/>
        </inSequence>
        <outSequence/>
        <faultSequence/>
    </target>
    <parameter name="transport.jms.ContentType">
        <rules>
            <jmsProperty>contentType</jmsProperty>
            <default>text/xml</default>
        </rules>
    </parameter>
    <parameter name="transport.jms.ConnectionFactory">myTopicConnectionFactory</parameter>
    <parameter name="transport.jms.DestinationType">topic</parameter>
    <parameter name="transport.jms.SubscriptionDurable">true</parameter>
    <parameter name="transport.jms.Destination">MY_TOPIC</parameter>
    <parameter name="transport.jms.DurableSubscriberName">TestJMSProxy</parameter>
    <parameter name="transport.jms.CacheLevel">consumer</parameter>
    <parameter name="transport.jms.DurableSubscriberClientID">1</parameter>
</proxy>

/repository/conf/axis2/axis2.xml中的JMS配置：

<transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
    <parameter name="myTopicConnectionFactory" locked="false">
        <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">failover:tcp://localhost:61616</parameter>
        <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
          <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
    </parameter>

    <parameter name="myQueueConnectionFactory" locked="false">
        <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">failover:tcp://localhost:61616</parameter>
        <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
          <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
    </parameter>

    <parameter name="default" locked="false">
        <parameter name="java.naming.factory.initial" locked="false">org.apache.activemq.jndi.ActiveMQInitialContextFactory</parameter>
      <parameter name="java.naming.provider.url" locked="false">failover:tcp://localhost:61616</parameter>
        <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
          <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
    </parameter>
</transportReceiver>

ESB控制台中出现的错误：

- ＆GT;好几次

我尝试过ActiveMQ 5.7和ActiveMQ 5.9，没有区别

您只需在JMS代理中更改此行，它就可以在WSO2 ESB v4.8中完美运行：<parameter name="transport.jms.SubscriptionDurable">false</parameter>

从队列或消息存储/消息处理器读取的JMS代理在WSO2 ESB 4.8中完美运行

Answer 1

这是一个错误，我创建了这个jira：https://wso2.org/jira/browse/ESBJAVA-2638 ant它将在ESB的最终4.8.0版本中得到解决

WSO2 ESB 4.8 JMS代理，在Apache ActiveMQ上具有持久订阅
