Apache Camel-发生异常时的延迟

Question

我需要做的是，当抛出异常时，我需要将处理延迟一段可配置的时间，比如15分钟。这将给服务器一些时间来稳定，而不是不必要地保持轮询。我正在使用骆驼的errorHandler机制，但它似乎不起作用。Camle不停地收到请求，没有任何延迟。请帮助解决这个问题。下面是束上下文快照：

<camel:onException>
        <camel:exception>java.lang.Exception</camel:exception>
        <camel:redeliveryPolicy backOffMultiplier="500" />
        <camel:log message="Default error handler was called"></camel:log>
    </camel:onException>
            <camel:route>
                <!--  Reading from REST url -->
                <camel:from uri="<my url>" />

                <camel:choice>
                    <camel:when>
                        <camel:xpath>Some path</camel:xpath>

                        <camel:log message="Recieved request ${headers.OrderNumber}-${headers.OrderVersion}.xml"/>
                        <camel:setHeader headerName="OrderNumber">

                        <!-- Request being put in file folder -->

                            uri="file:data/inbox?fileName=${header.OrderNumber}-${header.OrderVersion}.xml"

                    <!--  For all other requests put on  queue -->

                        <camel:log message="Request ${headers.OrderNumber}-${headers.OrderVersion}.xml directly sent to  queue"/>
                            <to uri="my queue"
                                pattern="InOut" />

                    <to uri="my queue"
                            pattern="InOut" />
            </camel:route>

Answer 1

您是否尝试了RedeliveryDelay中的RedeliveryPolicyProfile？

下面的策略配置文件将重试3次，每次尝试之间的延迟为1000ms。

<redeliveryPolicyProfile id="myRedeliveryProfile"
        maximumRedeliveries="3"
        redeliveryDelay="1000" allowRedeliveryWhileStopping="false"
        retryAttemptedLogLevel="INFO" />
