自SolR 5.x之后，子实体SolrEntityProcessor停止工作

我使用这样的数据导入

<dataConfig>
    <document name="products">
        <entity
            name="outer"
            dataSource="my_datasource"
            pk="id"
            query="..."
            deltaQuery="..."
            deltaImportQuery="..."
        >
            <entity
                name="solr"
                processor="SolrEntityProcessor"
                url="http://127.0.0.1:8983/solr/${solr.core.name}"
                query="Xid:${outer.Xid}"
                rows="1"
                fl="Id,FieldA,FieldB"
                wt="javabin"
            />
        </entity>
    </document>
</dataConfig>

这是Solr中的一个已知错误。连我都遇到过！我将此作为答案发布，因为这是一个错误，作者没有解决方案！我们实际上已经降低了版本，以摆脱这个错误。我不确定这是否有帮助，但这是我们在结束时所做的

更新：这可能对您有帮助，也可能没有帮助，但我们通过降级解决了问题。

可能对您有帮助。我不喜欢它，但它“有帮助”。你知道这个bug是什么时候出现的吗？你降级到哪个版本？@KingCrunch看看这个：发现了更多的东西。问题追踪器在这里：但我无法从我的办公室打开它。我们目前降级到Solr

4.3

。很抱歉告诉您，这是一个完全不同的问题。这个问题是关于导入期间SolrEntityProcessor关闭的，但是您链接的票证是关于参数替换的。。。关于我的问题的唯一票证是我创建的
