我有文件通道适配器,需要以指定的时间间隔收听目录。我有以下代码。

<file:inbound-channel-adapter id="fileAdapter"
         directory="file:${SYS.com.abc.wls.workdir}/finalize/" queue-size="1000"
    auto-startup="true" filename-pattern="*.txt">
<int:poller fixed-delay="500">          

</int:poller>       
 </file:inbound-channel-adapter>

directory="file:${SYS.com.abc.wls.workdir}/finalize/当我用一个真实的目录名(如) replcedirectory="file:C:/temp/finalize/一切正常。但是启动服务器时正在设置系统属性,但是spring没有检测到系统属性。

能否请你帮忙 ?

更新 :

我有以下占位符配置

<beans:bean id="jobProperties"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <beans:property name="properties">
        <beans:value>
            job.group.commit.interval=5000
        </beans:value>
    </beans:property>
    <beans:property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_FALLBACK" />
    <beans:property name="ignoreUnresolvablePlaceholders"
        value="true" />
    <beans:property name="order" value="1" />
</beans:bean>

已删除:file:directory="file:${SYS.com.abc.wls.workdir}/finalize/"并更改为auto-create-directory="false",现在我得到如下异常,

您需要声明一个识别系统属性的弹簧实体。典型的方法是PropertyPlaceHolderConfigurer在你的 Springconfiguration 中添加一个。

默认模式是SYSTEM_PROPERTIES_MODE_FALLBACK,这意味着配置器未保存的值将作为系统属性查找。可以使用 覆盖该模式setSystemPropertiesMode
