これが私の Schema.xml ファイルです。私はSOLRの初心者なので、これは簡単です。
<schema name="example" version="1.5">
<types>
<fieldtype name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0" />
<fieldtype name="text" class="solr.TextField" sortMissingLast="true" omitNorms="true" />
<fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
</types>
<fields>
<field name="user_id" type="text" indexed="true" stored="true" required="true" />
<field name="user_name" type="text" indexed="true" stored="false" />
<field name="_version_" type="long" indexed="true" stored="true" multiValued="false"/>
</fields>
<uniqueKey>user_id</uniqueKey>
</schema>
ここに私の db-data-config.xml があります。
<?xml version="1.0" encoding="UTF-8"?>
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/solr_user"
user="root"
password="waseem"
batchSize="-1" />
<document name="user">
<entity name="user" query="SELECT user_id, user_name FROM users">
<field column="user_id" name="id" />
<field column="user_name" name="name" />
</entity>
</document>
</dataConfig>
上記のコードの何が問題なのか、なぜこのエラーが発生するのか、誰か教えてください。任意の助けをいただければ幸いです。Ubuntuでjettyを使用しています。
