在Apache Solr DataImport中得到此错误：“无法执行查询”

Question

 <dataConfig>
    <dataSource type="JdbcDataSource"
     driver="com.mysql.jdbc.Driver"
     url="jdbc:mysql://localhost/mydb"
     user="root"
     password="root"
    />
    <document name="bestsellerscats_1">
       <entity name="bestsellerscats" query="SELECT id, name FROM testtable">
          <field column="id" name="id"/>
          <field column="name" name="name"/>
       </entity>
    </document>
  </dataConfig>

This is the error message:

Exception while processing: bestsellerscats document : SolrInputDocument(fields: []):org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT id, name FROM testtable Processing Document # 1

Any Help?

I think the problem is with your url. Try to maintain the following format.

jdbc:mysql://<ip>:<port>/<myDB>

In your case you need to have, if you are using the default mysql port.

url="jdbc:mysql://localhost:3306/mydb"
