【问题描述】:
我有文件通道适配器,它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:${SYS.com.abc.wls.workdir}/finalize/" queue-size="1000"
auto-startup="true" filename-pattern="*.txt">
<int:poller fixed-delay="500">
</int:poller>
</file:inbound-channel-adapter>
当我用真实的目录名(如directory="file:C:/temp/finalize/)替换directory="file:${SYS.com.abc.wls.workdir}/finalize/ 时,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。
你能帮忙吗?
更新:
占位符我有以下配置
<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>
从directory="file:${SYS.com.abc.wls.workdir}/finalize/" 中删除:file: 并更改为auto-create-directory="false",现在我得到如下异常,
by: java.lang.IllegalArgumentException: Source directory **[${SYS.com.abc.wls.workdir}\finalize] does not exist**.
