Spring integration jpa入站通道适配器没有'；t支持参数源

我试图使用参数源在入站通道适配器中为我的查询提供一个参数，但它似乎不起作用。我已经浏览了解析器代码，我认为它没有处理参数源

<int-jpa:inbound-channel-adapter delete-after-poll="true"
    delete-in-batch="true" auto-startup="true" flush-after-delete="true"
    max-results="2000"
    entity-manager-factory="entityManagerFactory"
    entity-class="AuditMessage"
    channel="processMessage"
    jpa-query="select a from AuditMessage a where a.updateTs &lt; :purgeDate"
    parameter-source="parameterSource">
    <int:poller cron="*/5 * * * * *" >
        <int:transactional transaction-manager="transactionManager"/>
    </int:poller>
</int-jpa:inbound-channel-adapter>

<bean id="parameterSource" factory-bean="spelSource"
            factory-method="createParameterSourceNoCache">
    <constructor-arg value="" />
</bean>

<bean id="spelSource"
    class="org.springframework.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
    <property name="parameterExpressions">
        <map>
            <entry key="purgeDate"
                value="new java.sql.Timestamp(T(System).currentTimeMillis()-(T(java.util.concurrent.TimeUnit).MILLISECONDS.convert(${eam.integration.arcgis.purge.daysToKeep}, T(java.util.concurrent.TimeUnit).DAYS)))" />
        </map>
    </property>
</bean>

我使用的是spring版本4.0.3。我做错什么了吗？还是有其他方法提供查询参数？

我想您刚刚发现了一个bug

JpaInboundChannelAdapterParser

只是不解析

参数源

属性。请随意提出错误

作为一种解决方法，您必须将

JpaPollingChannelAdapter

配置为原始

，注入

JpaExecutor

，并将其用作通用

中的

ref
