Solr导入MySql中的数据

1、参照 http://www.cnblogs.com/luxh/p/5016894.html 部署好solr的环境

2、在solr_home下建立一个core_item目录

[root@iZ23exixsjaZ solr_home]# pwd
/luxh/solr/solr_home
[root@iZ23exixsjaZ solr_home]# mkdir core_item

　　在core_item目录中建立data目录

[root@iZ23exixsjaZ core_item]# pwd
/luxh/solr/solr_home/core_item
[root@iZ23exixsjaZ core_item]# mkdir data

3、将/luxh/solr/solr-5.3.1/example/example-DIH/solr/db路径下的conf目录拷贝到刚才创建的core_item目录中

[root@iZ23exixsjaZ data_driven_schema_configs]# pwd
/luxh/solr/solr-5.3.1/example/example-DIH/solr/db
[root@iZ23exixsjaZ data_driven_schema_configs]# cp -r conf /luxh/solr/solr_home/core_item

4、在solr管理界面配置添加一个core

5、拷贝相应的jar包到solr项目中

　　拷贝mysql-connector-java-5.1.37.jar和solr-dataimporthandler-5.3.1.jar到solr项目中

　　拷贝路径：

/luxh/solr/apache-tomcat-8.0.29/webapps/solr/WEB-INF/lib

6、配置solrconfig.xml，加入solr数据导入处理器（其实从solr拷贝过来的文件已经配置好了）

  <requestHandler name="/dataimport" class="solr.DataImportHandler">
    <lst name="defaults">
      <str name="config">db-data-config.xml</str>
    </lst>
  </requestHandler>

7、配置db-data-config.xml，加入连接数据库的信息，按自己的实际字段配置

<dataConfig>
  <dataSource  name="testDB" type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://127.0.0.1:3306/fashion?rewriteBatchedStatements=true&amp;useUnicode=true&amp;characterEncoding=utf8&amp;autoReconnect=true" user="root" password="root" />
  <document>
    <entity  name="item" query="select * from item">
        <field column="Uuid" name="id"/>
        <field column="ShopId" name="ShopId"/>
        <field column="Cat" name="Cat"/>
        <field column="Building" name="Building"/>
        <field column="Floor" name="Floor"/>
        <field column="Position" name="Position"/>
        <field column="Title" name="Title"/>
        <field column="Price" name="Price"/>
        <field column="Color" name="Color"/>
        <field column="Size" name="Size"/>
        <field column="Input_str" name="Input_str"/>
    </entity>
  </document>
</dataConfig>

　　column表示数据库中的列；name是solr的schema.xml配置的field的name

8、配置solr的schema.xml，加入一下内容：

   <field name="ShopId" type="int" indexed="false" stored="true"/>
   <field name="Cat" type="text_ansj" indexed="true" stored="true"/>
   <field name="Building" type="text_ansj" indexed="true" stored="true"/>
   <field name="Floor" type="int" indexed="false" stored="true"/>
   <field name="Position" type="text_ansj" indexed="true" stored="true"/>
   <field name="Title" type="text_ansj" indexed="true" stored="true"/>
   <field name="Price" type="float" indexed="true" stored="true"/>
   <field name="Color" type="text_ansj" indexed="true" stored="true"/>
   <field name="Input_str" type="text_ansj" indexed="true" stored="true"/>
   <field name="Size" type="text_ansj" indexed="true" stored="true"/>
  
   <field name="allwords" type="text_ansj" indexed="true" stored="false" multiValued="true"/>

   
   
   <copyField source="Cat" dest="allwords"/>
   <copyField source="Title" dest="allwords"/>
   <copyField source="Color" dest="allwords"/>
   <copyField source="Input_str" dest="allwords"/>
   <copyField source="Size" dest="allwords"/>

9、配置好中文分词器

　　参照 http://www.cnblogs.com/luxh/p/5017336.html

10、启动tomcat

11、导入数据

12、如果日志中有SolrResourceLoader Can't find (or read) directory to add to classloader: ../../../contrib/extraction/lib等找不到库的警告，

　　主要是找不到solr安装目录中的solr-5.3.1/contrib和  solr-5.3.1/dist.   则在solrconfig.xml中指定这两个目录的路径即可

  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/extraction/lib" regex=".*.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-d.*.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/clustering/lib/" regex=".*.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-clustering-d.*.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/langid/lib/" regex=".*.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-langid-d.*.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/velocity/lib" regex=".*.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-velocity-d.*.jar" />

替换为：
  <lib dir="/luxh/solr/solr_home/dist/" regex="solr-dataimporthandler-.*.jar" />

  <lib dir="/luxh/solr/solr_home/contrib/extraction/lib" regex=".*.jar" />
  <lib dir="/luxh/solr/solr_home/dist/" regex="solr-cell-d.*.jar" />

  <lib dir="/luxh/solr/solr_home/contrib/clustering/lib/" regex=".*.jar" />
  <lib dir="/luxh/solr/solr_home/dist/" regex="solr-clustering-d.*.jar" />

  <lib dir="/luxh/solr/solr_home/contrib/langid/lib/" regex=".*.jar" />
  <lib dir="/luxh/solr/solr_home/dist/" regex="solr-langid-d.*.jar" />

  <lib dir="/luxh/solr/solr_home/contrib/velocity/lib" regex=".*.jar" />
  <lib dir="/luxh/solr/solr_home/dist/" regex="solr-velocity-d.*.jar" />
