使用 ContentStreamUpdateRequest 将 doc/pdf/docx 文件索引到 solr 中

Question

嗨，我在这里使用 Solr 4.7.2 为文档编制索引。

使用ContentStreamUpdate请求solrj我正在尝试在Solr中索引文件，但是虽然我正在使用UI发送文件路径和唯一ID字段作为输入

在发送 ContentStreamUpdateRequest 的对象时的操作类中，将参数传递给 solrServer 对象即

SolrServer solrServer = ..;
solrServer.request(contentStreamUpdateRequest);

我收到以下错误

Exception:
    org.apache.solr.client.solrj.SolrServerException
Exception message:
    error reading streams

异常跟踪：

可以建议我修复它。

Answer 1

我认为在 4.7.2 版中默认情况下禁用流式传输，您必须在文件 solrconfig 中启用它.xml

改变

<requestParsers enableRemoteStreaming="false" 

自

<requestParsers enableRemoteStreaming="true" 

另外，请查看文档http://wiki.apache.org/solr/SolrSecurity#Streaming_Consideration

让我知道这是否解决了问题。启用远程流式处理时请注意安全性。
