Solr错误创建核心：fieldType [x]在模式中找不到 [英] Solr error creating core: fieldType [x] not found in the schema

问题描述

我试图得到一个Solr核心运行与我自己的 schema.xml ，但Solr（版本5.2.1）不断抱怨缺少 c>

$

 $ 
 
 $ 
  org.apache.solr.common.SolrException：在模式中找不到fieldType'booleans'
  
每当我添加一个'missing' fieldtype 时，出现另一个错误，抱怨另一个 fieldType  code> longs 等等，直到我添加了所有的，并且接受没有错误的模式。
 
 
 
当没有使用它们时，我必须提供这些 fieldtype 元素？
 
 
 
在 .xml 我有：
 < schemaFactory class =ClassicIndexSchemaFactory/& 
  
这是我的 schema.xml ：
 
 
 
 < schema name =collectionsversion =1.5> 
 
< fields> 
< field name =id_objecttype =stringindexed =truestored =true/>

< fieldtype name =textclass =solr.TextField/> 
< / types> 
 
< / schema> 
  
没有一个 multiValued 那里。尽管如此，我尝试为每个字段单独显式设置 multiValued ='false'，但无效。即使当我将整个模式剥离到只有少数 String 字段时，它仍会生成该错误。
 
 
 
 'm很有信心我的 schema.xml 是确定的，但也许某些地方的某些设置应该告诉Solr容易。
解决方案
 
 < lst name =typeMapping> 
< str name =valueClass> java.lang.Boolean< / str> 
< str name =fieldType> booleans< / str> 
< / lst> 
  
在这里你需要将booleans改为boolean。
 < lst name =typeMapping> 
< str name =valueClass> java.lang.Boolean< / str> 
< str name =fieldType> boolean< / str> 
< / lst> 
  
然后就可以了。

I am trying to get a Solr core running with my own schema.xml, but Solr (version 5.2.1) keeps complaining about missing fieldType elements that aren't even in my fields definitions.
org.apache.solr.common.SolrException: fieldType 'booleans' not found in the schema
Whenever I add a 'missing' fieldtype another error pops up complaining about another fieldType missing, like longs, etc., until I've added them all and the schema is accepted without error.

Now how come I must provide these fieldtype elements when there is no use for them?

In config.xml I have:
<schemaFactory class="ClassicIndexSchemaFactory"/>
Here's my schema.xml:
<schema name="collections" version="1.5">

<fields>
    <field name="id_object" type="string" indexed="true" stored="true" />
    <field name="id_organization" type="string" indexed="true" stored="true"  />
    <field name="title" type="string" indexed="true" stored="true"  />
    <field name="artist" type="string" indexed="true" stored="true"  />
    <field name="searchname" type="string" indexed="true" stored="true"  />
    <field name="technique_group" type="string" indexed="true" stored="true"  />
    <field name="technique" type="string" indexed="true" stored="true"  />
    <field name="color_type" type="string" indexed="true" stored="true"  />
    <field name="color" type="string" indexed="true" stored="true"  />
    <field name="subject" type="string" indexed="true" stored="true"  />
    <field name="height" type="tint" indexed="true" stored="true"  />
    <field name="width" type="tint" indexed="true" stored="true"  />
    <field name="depth" type="tint" indexed="true" stored="true"  />
    <field name="price_sale" type="tfloat" indexed="true" stored="true"  />
    <field name="price_rental" type="tfloat" indexed="true" stored="true"  />
    <field name="price_rental_with_savings" type="tfloat" indexed="true" stored="true"  />
    <field name="savings_portion" type="tfloat" indexed="true" stored="true"  />
    <field name="year" type="tint" indexed="true" stored="true"  />
    <field name="is_for_rent" type="boolean" indexed="true" stored="true"  />
    <field name="is_for_sale" type="boolean" indexed="true" stored="true"  />
    <field name="status" type="string" indexed="true" stored="true"  />
    <field name="shipment" type="tfloat" indexed="true" stored="true"  />
    <field name="timestamp" type="tdate" indexed="true" stored="true" default="NOW" />

    <!-- catch all field, must be multiValued if any of its source fields is -->
    <field name="quick_search" type="text" indexed="true" stored="false" />

    <!-- mandatory -->
    <field name="_version_" type="tlong" indexed="true" stored="true" />

</fields>

<uniqueKey>id_object</uniqueKey>

<copyField source="id_object" dest="quick_search" />
<copyField source="title" dest="quick_search" />
<copyField source="artist" dest="quick_search" />
<copyField source="searchname" dest="quick_search" />
<copyField source="technique_group" dest="quick_search" />
<copyField source="technique" dest="quick_search" />
<copyField source="color_type" dest="quick_search" />
<copyField source="color" dest="quick_search" />
<copyField source="subject" dest="quick_search" />

<types>
    <fieldtype name="string" class="solr.StrField" />
    <fieldtype name="boolean" class="solr.BoolField" />
    <fieldtype name="tint" class="solr.TrieIntField" />
    <fieldtype name="tlong" class="solr.TrieLongField" />
    <fieldtype name="tfloat" class="solr.TrieFloatField" />
    <fieldtype name="tdate" class="solr.TrieDateField" />
    <fieldtype name="text" class="solr.TextField"/>
</types>

</schema>
There is not a single multiValued field in there. Nonetheless I tried explicitly setting multiValued='false' for each field individually, but to no avail. Even when I strip the entire schema down to just a handful of String fields it still generates that error.

I'm pretty confident my schema.xml is OK but perhaps some setting somewhere should tell Solr to take it easy.
解决方案
<lst name="typeMapping">
    <str name="valueClass">java.lang.Boolean</str>
    <str name="fieldType">booleans</str>
</lst>
over here you need to correct "booleans" to "boolean".
<lst name="typeMapping">
    <str name="valueClass">java.lang.Boolean</str>
    <str name="fieldType">boolean</str>
</lst>
Then it will work..
