我有文件通道适配器,需要以指定的时间间隔侦听目录。我有以下代码。在春季配置系统属性
<file:inbound-channel-adapter id="fileAdapter"
directory="file:${SYS.com.abc.wls.workdir}/finalize/" queue-size="1000"
auto-startup="true" filename-pattern="*.txt">
<int:poller fixed-delay="500">
</int:poller>
</file:inbound-channel-adapter>
当我replce directory="file:${SYS.com.abc.wls.workdir}/finalize/
一个真正的目录名称(如directory="file:C:/temp/finalize/
)一切工作正常。但系统属性是在启动服务器时设置的,但是spring没有检测到系统属性。
你能帮忙吗?
更新:
我为占位
<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>
以下配置中删除:file:
从directory="file:${SYS.com.abc.wls.workdir}/finalize/"
并变更为auto-create-directory="false"
,现在我gettign例外如下,
by: java.lang.IllegalArgumentException: Source directory **[${SYS.com.abc.wls.workdir}\finalize] does not exist**.

@ JohanSjöberg。你的意思是我应该在PropertyPlaceholderConfigure中将 设置为SYSTEM_PROPERTIES_MODE_FALLBACK? –
