Solr7.x学习1-导入数据

导入配置可参考官网：http://lucene.apache.org/solr/guide，http://lucene.apache.org/solr/guide/7_7/

1、创建field，修改managed-schema文件，添加字段信息

  <field name="id" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
  <field name="code" type="strings" uninvertible="true" indexed="true" stored="true"/>
  <field name="name" type="text_ik" uninvertible="true" indexed="true" stored="true"/>
  <field name="remark" type="text_ik" uninvertible="true" indexed="true" stored="true"/>
  <field name="usable" type="boolean" uninvertible="true" indexed="true" stored="true"/>
  <field name="addr" type="text_it" uninvertible="true" indexed="true" stored="true"/>
  <field name="age" type="pint" uninvertible="true" indexed="true" stored="true"/>
  <field name="birthday" type="pdate" uninvertible="true" indexed="true" stored="true"/>
  <field name="deptId" type="pint" uninvertible="true" indexed="true" stored="true"/>
  <field name="createTime" type="pdate" uninvertible="true" indexed="true" stored="true"/>

    也可以通过url添加，两种添加方式是等效的，url添加的字段会写入managed-schema文件中

 

2、修改solrconfig.xml文件，添加配置

  <requestHandler name="/import" class="org.apache.solr.handler.dataimport.dataimporthandler">
    <lst name="defaults">
      <str name="config">db-config.xml</str>
    </lst>
  </requestHandler>

3、在同目录创建db-config.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<dataConfig>
  <dataSource type="JdbcDataSource" driver="com.MysqL.cj.jdbc.Driver"
              url="jdbc:MysqL://39.97.174.153:3306/zhi_test?characterEncoding=utf8"
              user="root" password="root"/>
  <document>
    <entity name="dept"
            query="select id,code,name,remark,create_time from dept">
      <field column="create_time" name="createTime"/>
    </entity>
        <entity name="person"
            query="select * from person"
            deltaQuery="select id from person where create_time>'${dataimporter.last_index_time}'"
            deltaimportQuery="select * from person where id='${dih.delta.id}'">
      <field column="dept_id" name="deptId"/>
      <field column="create_time" name="createTime"/>
    </entity>
  </document>
</dataConfig>

4、复制solr-7.7.2\dist目录下的solr-dataimporthandler-7.7.2.jar和solr-dataimporthandler-extras-7.7.2.jar到solr-7.7.2/server/solr-webapp/webapp/WEB-INF/lib目录下

5、复制MysqL驱动到solr-7.7.2/server/solr-webapp/webapp/WEB-INF/lib目录下

6、开始导入输入数据
