如何在文件到队列的骆驼路由上配置重新传递策略？

Question

public class DemoHelperRouteBuilder extends RouteBuilder {

@Override
public void configure() throws Exception {


    onException(JmsException.class, ConnectException.class)
    .routeId("ConnectionExceptionRoute")
    .handled(true)
    .log(LoggingLevel.ERROR, "Connection Error")
    .maximumRedeliveries(5)
    .redeliveryDelay(1000)
    .backOffMultiplier(2)
    .useExponentialBackOff()
    .maximumRedeliveryDelay(60000)
    .log(LoggingLevel.DEBUG, "Rolling back!")
    .rollback();



    errorHandler(defaultErrorHandler()
            .maximumRedeliveries(20).redeliveryDelay(7000).retryAttemptedLogLevel(LoggingLevel.INFO));

    from("file:{{directory.property}}?delete=true&readLock=markerFile&delay=5000")
    .log("Passing File")
    .transacted("PROPAGATION_REQUIRED")
    .setHeader("FILE_TYPE", constant("MYTYPE"))
    .setHeader("MSG_ID", constant("55"))
    .to("activemq:{{MY.QUEUE}}"); 

}

}

我的骆驼上下文文件如下所示：

<!-- This is the default behavior. -->
<bean id="PROPAGATION_REQUIRED" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
    <property name="transactionManager" ref="jmsTransactionManager"/>
</bean>

<bean id="PROPAGATION_REQUIRES_NEW" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
    <property name="transactionManager" ref="jmsTransactionManager"/>
    <property name="propagationBehaviorName" value="PROPAGATION_REQUIRES_NEW"/>
</bean>


<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
    <property name="connectionFactory" ref="jmsConnectionFactory"></property>
    <property name="transacted" value="true"/>
    <property name="transactionManager" ref="jmsTransactionManager"/>
</bean>

<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
    <property name="brokerURL" value="${jms.broker.url}"/>
    <property name="redeliveryPolicy">
        <bean class="org.apache.activemq.RedeliveryPolicy">
            <property name="maximumRedeliveries" value="-1" />
            <property name="redeliveryDelay" value="10000" />
        </bean>
    </property>
</bean>

我在应用程序中的各种不同endpoint之间有几条其他路由，它们需要重新传递配置，并且按照预期的方式运行。但是，这个特定的路由类型（从文件到队列）似乎并不遵循我配置的任何重新传递策略。当我关闭ActiveMQ代理时，路由会尝试每6秒重新传递一次文件。：

10:54:17,088 WARN c_demo%5GenericFileOnCompletion 105-org.apache.camel.camel-core-2.10.0.redhat-60024回滚文件策略：org.apache.camel.component.file.strategy.genericfileDeleteProcessStrategy@789d315e for file:genericfile[]

我查看了事务性客户端文档和其他站点，但一直未能找到解决方案。如果我错过了一些告诉我如何解决这个问题的东西，我道歉。任何可以帮助解决此问题的指针或文档都将非常感谢。谢谢！

我可以通过稍微更改路由来配置路由：

public class DemoHelperRouteBuilder extends SpringRouteBuilder{

@Override
public void configure() throws Exception {


onException(JmsException.class, ConnectException.class)
.routeId("ConnectionExceptionRoute")
.handled(true)
.log(LoggingLevel.ERROR, "Connection Error")
.maximumRedeliveries(25)
.redeliveryDelay(1000)
.backOffMultiplier(2)
.useExponentialBackOff()
.maximumRedeliveryDelay(60000)
.log(LoggingLevel.DEBUG, "Rolling back!")
.rollback();



 errorHandler(transactionErrorHandler()
    .maximumRedeliveries(5).redeliveryDelay(60000).retryAttemptedLogLevel(LoggingLevel.INFO)); 

from("file:{{directory.property}}?delete=true&readLock=markerFile&delay=5000")
.log("Passing File")
.transacted("PROPAGATION_REQUIRED")
.setHeader("FILE_TYPE", constant("MYTYPE"))
.setHeader("MSG_ID", constant("55"))
.to("activemq:{{MY.QUEUE}}"); 

}

}

<bean id="JMS_TRANSACTED" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
    <property name="transactionManager" ref="jmsTransactionManager"/>
</bean>
<bean id="PROPAGATION_REQUIRED" class="org.apache.camel.spring.spi.SpringTransactionPolicy"> 
            <property name="transactionManager"> 
                   <osgi:reference interface="org.springframework.transaction.PlatformTransactionManager" /> 
            </property> 
            <property name="propagationBehaviorName" value="PROPAGATION_REQUIRED" /> 
</bean> 

<bean id="PROPAGATION_REQUIRES_NEW" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
    <property name="transactionManager" ref="jmsTransactionManager"/>
    <property name="propagationBehaviorName" value="PROPAGATION_REQUIRES_NEW"/>
</bean>

<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="${jms.broker.url}"/>
<property name="redeliveryPolicy">
    <bean class="org.apache.activemq.RedeliveryPolicy">
        <property name="maximumRedeliveries" value="-1" />
        <property name="redeliveryDelay" value="10000" />
    </bean>
</property>
</bean>
