java - Spring 集成 : error-channel - Problems with exception handling

Question

你好，这是我的配置:

1. JVM 1.6.0_30
2. Spring 版本 3.0.5
3. Spring Integration 核心 2.0.5
4. 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
        exception-type="com.cervedgroup.rating.pds.exceptions.DataSourcePDSException"
        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

log4j.logger.org.apache.ibatis=INFO, ME
log4j.logger.org.mybatis.spring=INFO, ME
log4j.logger.org.springframework=INFO, ME

我在网关错误 channel 的管理上遇到了问题。该 channel 有效，但在 nohup 上打印了异常的堆栈跟踪:

有没有办法在 nohup 上避免打印？

非常感谢

如你所知errorChannel由Framework在后台创建，自己定义没有限制。

默认为 PublishSubscribeChannel并且框架为其订阅了一个处理程序 - LoggingHandler与 ERROR日志级别。

因此，如果您对默认的 debaviour 不感兴趣，您可以声明 errorChannel因为它适合您的环境。

从另一边看，当你从 <gateway> 使用它时，如何使用您自己的 channel 而不是默认的 errorChannel ？
