Solrnet 中的提取参数(AbstractMethodError)
ExtractParameters in Solrnet (AbstractMethodError)
我正在尝试使用 solrnet 客户端提取 pdf 数据。我的代码如下:
using (MemoryStream stream = new MemoryStream((byte[])dataReader["file_stream"]))
{
var solr = ServiceLocator.Current.GetInstance<ISolrOperations<Contribution>>();
ExtractParameters extract = new ExtractParameters(stream, "doc1", dataReader["nome_original"] + "")
{
ExtractOnly = true,
ExtractFormat = ExtractFormat.Text/*,
StreamType = "application/pdf"*/
};
var response = solr.Extract(extract);
Debug.WriteLine("\n+++++++++++++++++++++++++++++++ " + response.Content);
}
但是我收到了您可以在下面看到的错误:

基本上 dataReader["file_stream"]
是数据库中的一个 BLOB,我想获取此文件中的所有文本。
谁能帮帮我?
谢谢
我已经修好了。这是 JARS 的错误安装。
我正在添加:
<lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" />
和
<lib dir="../../../dist/" regex=".*\.jar" />
因为我有两个 JARS(apache-solr-cell-3.5.0 和 solr-cell-5.5.0)solr很困惑选择哪一个生成 AbstractMethodError.
