Solr数据导入已获取12/12，但已处理0/12

Question

solr7.5

尝试调试我的Solr数据导入。在solr ui上查看日志可以得到以下信息：

我一直在查看我的solrconfig.xml，schema.xml和db-config.xml。 下面是架构和dbconfig

SCHEMA

<?xml version="1.0" encoding="UTF-8"?>
<schema name="testing" version="1.6">
    <uniqueKey>id</uniqueKey>
    <types>
        <fieldtype name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true" />
        <fieldType name="plong" class="solr.LongPointField" docValues="true"/>
        <fieldtype name="ignored" stored="false" indexed="false" multiValued="true" class="solr.StrField" />
        <fieldType name="pdate" class="solr.DatePointField" sortMissingLast="true" />
        <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" multiValued="true">
        <analyzer type="index">
          <tokenizer class="solr.StandardTokenizerFactory"/>
          <filter class="solr.StopFilterFactory" words="stopwords.txt" ignoreCase="true"/>
          <filter class="solr.LowerCaseFilterFactory"/>
        </analyzer>
        <analyzer type="query">
          <tokenizer class="solr.StandardTokenizerFactory"/>
          <filter class="solr.StopFilterFactory" words="stopwords.txt" ignoreCase="true"/>
          <filter class="solr.SynonymGraphFilterFactory" expand="true" ignoreCase="true" synonyms="synonyms.txt"/>
          <filter class="solr.LowerCaseFilterFactory"/>
        </analyzer>
    </fieldType>
    </types>
    <field name="_version_" type="plong" indexed="true" stored="true"/>
    <field name="Problem" type="text_general" indexed="true" stored="true" multiValued="false"/>
    <field name="Solution" type="text_general" indexed="true" stored="true" multiValued="false"/>
    <field name="_text_" type="text_general" multiValued="false" indexed="true" stored="false"/>
    <field name="date" type="pdate" multiValued="false" indexed="true" stored="true"/>
    <field name="id" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
    <copyField source="*" dest="_text_"/>
</schema>

DB-CONFIG

<dataConfig>
<dataSource type="JdbcDataSource"
            driver="com.mysql.cj.jdbc.Driver"
            url="jdbc:mysql://localhost:3306/solrtest"
            user="root"
            password=""/>
    <document>
    <entity name="solr"
            pk="id"
            query="select * from solr"
        >
        <field column="id" name="id"/>
        <field column="date" name="date"/>
        <field column="Problem" name="Problem"/>
        <field column="Solution" name="Solution"/>
    </entity>
    </document>
</dataConfig>

Ive对solrconfig所做的更改包括以下内容：

更改了此内容

  <updateRequestProcessorChain name="add-unknown-fields-to-the-schema" default="${update.autoCreateFields:false}"
           processor="uuid,remove-blank,field-name-mutating,parse-boolean,parse-long,parse-double,parse-date"><!--,add-schema-fields-->
    <processor class="solr.LogUpdateProcessorFactory"/>
    <processor class="solr.DistributedUpdateProcessorFactory"/>
    <processor class="solr.RunUpdateProcessorFactory"/>
  </updateRequestProcessorChain>

添加了此内容

  <schemaFactory class="ClassicIndexSchemaFactory"/>

对此评论：

<updateRequestProcessorChain name="add-unknown-fields-to-the-schema" default="${update.autoCreateFields:false}"
           processor="uuid,remove-blank,field-name-mutating,parse-boolean,parse-long,parse-double,parse-date"><!--,add-schema-fields-->
    <processor class="solr.LogUpdateProcessorFactory"/>
    <processor class="solr.DistributedUpdateProcessorFactory"/>
    <processor class="solr.RunUpdateProcessorFactory"/>
  </updateRequestProcessorChain>

我正在寻找有关错误的更多详细信息的帮助。

将Debug和Verbose添加到导入尝试中时，出现错误提示

Answer 1

我的解决方案来自为问题和解决方案添加一个copyField。这样，我将 text 更改为多值。然后，在重新启动solr之后，我可以根据需要索引我的信息。

<copyField source="Problem" dest="_text_"/>
<copyField source="Solution" dest="_text_"/>
