Question

我正在尝试使用我自己的schema.xml运行Solr核心，但Solr（版本5.2.1）一直在抱怨缺少fieldType元素甚至不在fields中}定义。

org.apache.solr.common.SolrException: fieldType 'booleans' not found in the schema

每当我添加“遗失”fieldtype时，会弹出另一个错误，抱怨其他fieldType丢失，例如longs等，直到我添加了所有内容并且架构为接受没有错误。

现在为什么我必须在没有使用这些fieldtype元素时提供它们？

在config.xml我有：

<schemaFactory class="ClassicIndexSchemaFactory"/>

这是我的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>

那里没有一个multiValued字段。尽管如此，我尝试单独为每个字段明确设置multiValued='false'，但无济于事。即使我将整个架构剥离到少数String字段，它仍然会产生该错误。

我很自信我的schema.xml还可以，但也许某些设置应该告诉Solr放轻松。

Answer 1

不确定这是否是首选方式，但在solr.AddSchemaFieldsUpdateProcessorFactory中注释掉config.xml部分似乎可以解决问题。

<!--
<processor class="solr.AddSchemaFieldsUpdateProcessorFactory">
  <str name="defaultFieldType">strings</str>
  <lst name="typeMapping">
    <str name="valueClass">java.lang.Boolean</str>
    <str name="fieldType">booleans</str>
  </lst>
  <lst name="typeMapping">
    <str name="valueClass">java.util.Date</str>
    <str name="fieldType">tdates</str>
  </lst>
  <lst name="typeMapping">
    <str name="valueClass">java.lang.Long</str>
    <str name="valueClass">java.lang.Integer</str>
    <str name="fieldType">tlongs</str>
  </lst>
  <lst name="typeMapping">
    <str name="valueClass">java.lang.Number</str>
    <str name="fieldType">tdoubles</str>
  </lst>
</processor>
-->

Answer 2

<lst name="typeMapping">
    <str name="valueClass">java.lang.Boolean</str>
    <str name="fieldType">booleans</str>
</lst>

在这里你需要将“布尔”改为“布尔”。

<lst name="typeMapping">
    <str name="valueClass">java.lang.Boolean</str>
    <str name="fieldType">boolean</str>
</lst>

然后它会工作..
