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>
