Java SolrJ中缺少必需的唯一密钥字段错误

当我使用SimplePostTool为文件编制索引时,并没有类似的错误,但我想在我的网页中更新我的核心 您的模式中可能有一个字段设置为唯一键,如下所示:
<uniqueKey>id</uniqueKey>
id
问题在于,在本例中,通过ApachePOI上载文档时,没有为该唯一字段发送值
您有两个选择:
<uniqueKey>id</uniqueKey>
身份证件
...
...
uuid
您还需要更新提取处理程序:
<requestHandler name="/update/extract"
startup="lazy"
class="solr.extraction.ExtractingRequestHandler" >
<lst name="defaults">
...
<str name="update.chain">uuid</str>
</lst>

检查您准备的文档..它是否在创建和发布到solr时都有id字段…我检查了它,它有id字段
id
这是在我的模式中。xml检查您准备的文档..它是否在每次创建并发布到solr时都有id字段…我检查了它,它有id字段id
这在我的模式中。xml首先感谢您的回答。我做了选项2,它给了我这样的错误unknown UpdateRequestProcessorChain:uuid
我更新了答案以使用提取句柄中更新的uuid我更新了提取句柄,但它给了我第一个错误文档缺少必需的uniqueKey字段:id
:(您的java代码设置了“id”)在某些情况下,document.addField(“id”,currentCell.getNumericCellValue());您是否尝试过始终使用您自己的UUID设置它?不,我也不知道我是怎么做的。首先感谢您的回答。我做了选项2,它会给我这样的错误unknown UpdateRequestProcessorChain:UUID
我更新了答案以使用解压处理程序中更新的UUID我更新了解压处理程序,但它ves me第一个错误文档缺少必需的uniqueKey字段:id
