私はSolrの初心者です。複数のテーブルに対して full_import コマンドを実行すると、正常に動作します。更新された日付がdataimport.propertiesファイルに書き込まれます。デルタインポートを実行すると、コンテキストの初期化中に例外が発生しました..

クエリ deltaImportQuery anddeltaQuery indata-config.xml` は次のとおりです。

<dataConfig>
<dataSource name="JdbcDataSource" 
    driver="com.mysql.jdbc.Driver" 
    url="jdbc:mysql://localhost:3306/hellodb" 
    user="root" 
    password="root" 
    batchSize="-1" />

<document>

<entity name="bhushan"         datasource="jdbcDataSource"  pk="id"         query="select * from bhushan" 
                               deltaImportQuery="select * from bhushan where id=='${dataimporter.delta.id}'"
                               deltaQuery="select id from bhushan where last_modified &gt; '${dataimporter.last_index_time}'"/>



<entity name="sunny"          datasource="jdbcDataSource"   pk="id"     
                              query="select weight as sunny from sunny where id='${bhushan.ID}'"
                              deltaQuery="select id from sunny where last_modified > '${dataimporter.last_index_time}'"
                              parentDeltaQuery="select id from bhushan where ID=${sunny.id}"/>
enter code here

</entity>

</entity>

</document>
</dataConfig>
