java - Spring Integration:错误 channel -异常处理问题

您好，这是我的配置:

JVM 1.6.0_30

Spring 版本3.0.5

Spring Integration核心2.0.5

S.O. Windows 7

这是我的上下文配置:

<beans:bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
    lazy-init="false">
    <beans:property name="ignoreUnresolvablePlaceholders"
        value="true" />
    <beans:property name="location" value="classpath:etc/pds/pds.properties" />
</beans:bean>



<channel id="pdsrequest" />
<channel id="pdsresponse" />
<channel id="channelMBD"/>

<channel id="pdsRisposta">
    <queue capacity="1" />
    <interceptors>
        <wire-tap channel="simple" />
    </interceptors>
</channel>

<service-activator input-channel="pdsrequest"
    output-channel="pdsresponse" ref="pdsCalculateService" />

<logging-channel-adapter id="simple" level="DEBUG" />

<!-- GATEWAY -->
<gateway id="gatewayService"
    service-interface="com.cervedgroup.rating.pds.orchestratore.spring.GatewayService"
    error-channel="errorChannel" default-reply-timeout="${PDS.GATEWAY_TIMEOUT}"
    default-request-channel="pdsrequest" default-reply-channel="pdsresponse" />


<exception-type-router input-channel="errorChannel">
    <mapping
        exception-type="com.cervedgroup.rating.pds.exceptions.NotDefinedPDSException"
        channel="eccezioneProgrammata" />
    <mapping exception-type="com.cervedgroup.rating.pds.exceptions.ComputingPDSException"
        channel="eccezioneRuntime" />
    <mapping

        channel="eccezioneRuntime" />
    <mapping exception-type="com.cervedgroup.rating.pds.exceptions.PDSException"
        channel="eccezioneRuntime" />
    <mapping
        exception-type="com.cervedgroup.rating.pds.exceptions.ConfigurationException"
        channel="eccezioneRuntime" />
    <mapping exception-type="java.lang.RuntimeException" channel="eccezioneRuntime" />
</exception-type-router>

<service-activator input-channel="eccezioneProgrammata"
    ref="invokerHandlerEccezioneProgrammata" />

<beans:bean id="invokerHandlerEccezioneProgrammata"
    class="com.cervedgroup.rating.pds.orchestratore.error.GestoreEccezioneProgrammata" />

<service-activator input-channel="eccezioneRuntime"
    ref="invokerHandlerEccezioneRuntime" />

<beans:bean id="invokerHandlerEccezioneRuntime"
    class="com.cervedgroup.rating.pds.orchestratore.error.GestoreEccezioneRuntime" />


/>

</beans:beans>

这是我的log4j.properties:

log4j.rootLogger=INFO, ROOT
log4j.appender.ROOT=org.apache.log4j.ConsoleAppender
log4j.appender.ROOT.layout=it.pitagora.util.log.CervedLayout

我在网关错误通道的管理中有问题。该通道有效，但在nohup上会打印异常的堆栈跟踪:

有没有办法避免在nohup上打印此文字？

非常感谢你

最佳答案

您知道errorChannel是由Framework在后台创建的，但是您自己定义它没有任何限制。

默认情况下，它是PublishSubscribeChannel，并且框架向其订阅一个处理程序-具有LoggingHandler日志记录级别的ERROR。

因此，如果您对默认默认操作不感兴趣，则可以声明errorChannel，因为它适合您的环境。

另一方面，当您从<gateway>中使用它时，如何使用您自己的频道而不是默认的errorChannel？
