Solr DIH Quick Start

Step 1 : Edit your solrconfig.xml to add the request handler

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">

    <lst name="defaults">

      <str name="config">data-config.xml</str>

    </lst>

</requestHandler>

 

Step 2 : Create a data-config.xml file as follows and save it to the conf dir

<dataConfig>

  <dataSource type="JdbcDataSource" 

              driver="com.mysql.jdbc.Driver"

              url="jdbc:mysql://127.0.0.1/dbname" 

              user="test" 

              password="test1"  />

  <document>

    <entity name="first" 

            query="SELECT id, name FROM test">

    </entity>

  </document>

</dataConfig>

如果上面 的url参数写错，如写成jdbc:mysql://127.0.0.1:8080/dbname

可以看到如下信息：

信息: Creating a connection for entity first with URL: jdbc:mysql://127.0.0.1:8080/dbname

正确的值应当等于下图中host的值：

Step 3 : Ensure that your solr schema (schema.xml) has the fields 'id', 'name', 'desc'. Change the appropriate details in the data-config.xml

 

Step 4: 把下面组件放到<solr-home>/lib 目录

mysql-connector-java-5.1.19-bin.jar

apache-solr-dataimporthandler-extras-3.5.0.jar

 

Step 5 : Run the command http://localhost:8983/solr/dataimport?command=full-import

<response>　　

...

    <str name="Total Requests made to DataSource">1</str>

    <str name="Total Rows Fetched">2</str>

    <str name="Total Documents Skipped">0</str>

...

</response>

 

Step 6: 验证

http://localhost:8983/solr/select/?q=terrya&version=2.2&start=0&rows=10&indent=on

<result name="response" numFound="1" start="0">

<doc>

<str name="id">SD453</str>

<str name="name">terrya</str>

</doc>

</result>
