Question

我使用activeMq 5.10在tomee 1.7.1中部署了一个简单的spring应用程序。我的问题是，我设定的重新交付政策似乎主要被忽略了，主要是延迟交还。

我的jms监听器我立即抛出异常来测试自动重试。

我的activemq.xml是这样的：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:amq="http://activemq.apache.org/schema/core"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

">
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" />
<!-- 
    The <broker> element is used to configure the ActiveMQ broker. 
-->
<amq:broker xmlns="http://activemq.apache.org/schema/core" useShutdownHook="false" enableStatistics="true" brokerName="bima" useJmx="true" tmpDataDirectory="${catalina.base}/activemq-data/localhost/tmp_storage" populateJMSXUserID="true" useAuthenticatedPrincipalForJMSXUserID="true" schedulerSupport="true">

    <amq:connectionFactory id="jmsRedeliverConnectionFactory" brokerURL="vm://localhost">
      <amq:redeliveryPolicy>
        <amq:redeliveryPolicy maximumRedeliveries="5" initialRedeliveryDelay="1000" redeliveryUseExponentialBackOff ="true" backOffMultiplier="5" />
      </amq:redeliveryPolicy>

    <amq:persistenceAdapter>
        <amq:kahaDB directory="${catalina.base}/activemq-data/kahadb" checkForCorruptJournalFiles="true" checksumJournalFiles="true" journalMaxFileLength="32mb"/>
    </amq:persistenceAdapter>

    <managementContext>
       <managementContext createConnector="false"/>
    </managementContext>
</amq:broker>

我的tomee.xml看起来像这样：

<tomee>
    <Resource id="ActiveMQResourceAdapter" type="ActiveMQResourceAdapter">
        BrokerXmlConfig=broker:(vm://localhost)
        <!-- ServerUrl=vm://localhost -->
    </Resource>

  <!-- see http://tomee.apache.org/containers-and-resources.html -->
  <Resource id="resources/jms/ConnectionFactory" type="javax.jms.ConnectionFactory"> 
       ResourceAdapter = ActiveMQResourceAdapter 
       BrokerURL = vm://localhost
       maximumRedeliveries 3
       redeliveryBackOffMultiplier 2
       redeliveryUseExponentialBackOff true
       initialRedeliveryDelay 5000
       <!-- BrokerUrl = tcp://localhost:61616 -->
    </Resource> 

    <Resource id="resources/jms/XAConnectionFactory" class-name="org.apache.activemq.ActiveMQXAConnectionFactory">
        BrokerURL = vm://localhost

    </Resource>

    <Resource id="resources/jms/PrintQueue" type="javax.jms.Queue"/>


    <Resource id="testxa" class-name="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource">
        Url jdbc:mysql://localhost:3306/test?autoReconnect=true
        User root
    </Resource>

    <Resource id="movieDatabase" type="DataSource">
        XaDataSource testxa
        DataSourceCreator dbcp
        UserName root
    </Resource>

  <!-- activate next line to be able to deploy applications in apps -->
    <Deployments dir="apps" />
</tomee>

我的aplication上下文中的jms bean看起来像这样：

<bean id="StartQueue" class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory">
        <ref local="jmsFactory" />
    </property>
    <property name="defaultDestinationName" value="StartQueue" />
    <property name="deliveryPersistent" value="true"/>
    <property name="explicitQosEnabled" value="true"/>
</bean>
<bean id="starter" class="org.superbiz.mdb.Start"/>
<jms:listener-container container-type="default" connection-factory="jmsFactory" cache="none" acknowledge="auto" transaction-manager="transactionManager"  concurrency="1" >
    <jms:listener destination="StartQueue" ref="starter" />
</jms:listener-container>

一旦我将maximumRedeliveries 3添加到开始工作的tomee xml，但重新发送都没有延迟。所以有些东西忽略了useExponentialBackOff和initialRedeliveryDelay，或者我错过了将它设置在某个地方？

编辑：

所以我配置为使用外部代理activemq 5.10.0和代理配置

和tomee xml

    <tomee>

    <Resource id="ActiveMQResourceAdapter" type="ActiveMQResourceAdapter">
        # Do not start the embedded ActiveMQ broker
        BrokerXmlConfig  =
        ServerUrl = tcp://10.81.1.28:61617>
    </Resource>

    <Resource id="resources/jms/ConnectionFactory" type="javax.jms.ConnectionFactory"> 
        ResourceAdapter = ActiveMQResourceAdapter 
       maximumRedeliveries 1
    </Resource> 
    <Resource id="testxa" class-name="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource">
        Url jdbc:mysql://localhost:3306/test?autoReconnect=true
        User root
    </Resource>

    <Resource id="movieDatabase" type="DataSource">
        XaDataSource testxa
        DataSourceCreator dbcp
        UserName root
    </Resource>

  <!-- activate next line to be able to deploy applications in apps -->
    <Deployments dir="apps" />
</tomee>

当我尝试并且必须使用相同的activemq xml和tomee xml

启动activemq时，这样可以方便地重新传递队列

    <tomee>
    <Resource id="ActiveMQResourceAdapter" type="ActiveMQResourceAdapter">
        BrokerXmlConfig=broker:(vm://localhost)
        BrokerURL = vm://localhost
    </Resource>

  <Resource id="resources/jms/ConnectionFactory" type="javax.jms.ConnectionFactory">
       ResourceAdapter = ActiveMQResourceAdapter
       maximumRedeliveries 1
    </Resource>


    <Resource id="testxa" class-name="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource">
        Url jdbc:mysql://localhost:3306/test?autoReconnect=true
        User root
    </Resource>

    <Resource id="movieDatabase" type="DataSource">
        XaDataSource testxa
        DataSourceCreator dbcp
        UserName root
    </Resource>

  <!-- activate next line to be able to deploy applications in apps -->
    <Deployments dir="apps" />
</tomee>

配置被忽略，队列没有被重新传送到需要做的其他事情，所以tomee使用了重新传递策略？

Answer 1

我认为它是redeliveryUseExponentialBackOff而不是useExponentialBackOff：http://activemq.apache.org/maven/5.10.0/apidocs/org/apache/activemq/ra/ActiveMQManagedConnectionFactory.html

基本上使用setter。

Answer 2

为什么不在资源适配器BTW上设置它？

Answer 3

默认情况下，停用调度程序服务，因此这可能不适用于嵌入式代理。

您是否尝试使用外部添加jar来支持代理的xbean xml配置？（http://tomee.apache.org/jms-resources-and-mdb-container.html）

Answer 4

回答这个旧问题，以便也许有人可以从中受益（我遇到了很多类似的问题）。我有一个类似的问题，其中RedeliveryPolicy没有正确应用。通过将maximumRedeliveries设置为-1，可以无限地重试处理该消息，但是忽略了延迟。原来，由于Springs DefaultMessageListenerContainer上的默认cacheLevel字段，重新交付无法正常工作。

将此级别设置为CACHE_CONSUMER解决了该问题！

从tomee传递到spring时，activeMq redeliveryPolicy被忽略
