當我嘗試從DIH使用DIH導入數據，我得到了這個錯誤。HTTP錯誤500：Solr配置中的嚴重錯誤.Ruby on rails
HTTP ERROR 500
Problem accessing /solr/dataimport. Reason:
Severe errors in solr configuration.
Check your log files for more detailed information on what may be wrong.
If you want solr to continue after configuration errors, change:
<abortOnConfigurationError>false</abortOnConfigurationError>
in solr.xml

這裏是我的schema.xml代碼
<fields>
<field name="brands_test_id" type="string" indexed="true" stored="true" required="true" />
<field name="categories_test_id" type="string" indexed="true" stored="true" required="true" />
</fields>
而且數據-config.xml中有這樣的代碼：
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/Webpage"
user="test"
password="test123"/>
<document name="Products">
<entity name="products" query="select brands_test_id,categories_test_id from products"
<field name="brands_test_id" column="brands_test_id"
<field name="categories_test_id" column="categories_test_id"
<entity name="brands_test" query="select name from brands_test where id='$products.brands_test_id' "
<field name="brands_test" column="brands_test"/>
</entity>
<entity name="categories_test" query="select name from categories_test where id='$products.categories_test_id' "
<field name="categories_test" column="categories_test"/>
</entity>
</entity>
</document>
</dataConfig>
這裏是solrconfig.xml中的文件
<lib dir="../../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
我下載了mysql-connector-ja va-3.1.14.tar.gz並解壓縮並複製到lib目錄。 Ami正確定義文件目錄？請幫我解決這個問題。
