Question

声明

<field name="id" type="int" indexed="true" stored="true" required="true" 
 multiValued="false" />

schema.xml中的

会导致以下错误。

任何人都可以告诉我为什么会这样吗？

Answer 1

转到elevate.xml @ SOLR_HOME \ example \ example-DIH \ solr \ solr \ conf

以这种方式修改

<query text="ipod">
<!--   <doc id="MA147LL/A" />   put the actual ipod at the top 
   <doc id="IW-02" exclude="true" /> exclude this cable -->
 </query>

所以，你实际上注释掉了这两行导致你的异常

<doc id="MA147LL/A" />   put the actual ipod at the top 
<doc id="IW-02" exclude="true" /> exclude this cable

我希望它能解决你的问题。

Answer 2

您将id定义为int，并从错误消息中尝试将此内容MA147LL/A添加到其中（NumberFormatException：对于输入字符串：“MA147LL / A”at）。。

使用schema.xml中的以下行

<field name="id" type="string" indexed="true" stored="true" 
 required="true" multiValued="false" />

你应该没事

在solr中将唯一键声明为int会导致错误
