<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> </lst> </requestHandler> |
<pre class="brush: xml; gutter: false; first-line: 1; highlight: []; html-script: false"><lib dir="../../../dist/" regex="solr-dataimporthandler-\d.*\.jar"/></pre>
加在
<pre class="brush: xml; gutter: false; first-line: 1; highlight: []; html-script: false"> <lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" /></pre>
前面。
<?xml version="1.0" encoding="UTF-8" ?> <dataConfig> <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/django_blog" user="root" password=""/> <document name="blog"> <entity name="blog_blog" pk="id" query="select id,title,content from blog_blog" deltaImportQuery="select id,title,content from blog_blog where ID=‘${dataimporter.delta.id}‘" deltaQuery="select id from blog_blog where add_time > ‘${dataimporter.last_index_time}‘" deletedPkQuery="select id from blog_blog where id=0"> <field column="id" name="id" /> <field column="title" name="title" /> <field column="content" name="content"/> </entity> </document> </dataConfig> |
为数据库表字段建立域(field),编辑E:\solr-4.8.0\example\solr\collection1\conf\schema.xml:
<!-- mysql --> <field name="id" type="string" indexed="true" stored="true" required="true" /> <field name="title" type="text_cn" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true"/> <field name="content" type="text_cn" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true"/> <!-- mysql --> |
参考:
git clone https://github.com/10gen-labs/mongo-connector.git
cd mongo-connector
#安装前修改mongo_connector/constants.py的变量:设置DEFAULT_COMMIT_INTERVAL = 0
python setup.py install
默认是不会自动提交了,这里设置成自动提交,否则mongodb数据库更新,索引这边没法同时更新,或者在命令行中可以指定是否自动提交,不过我现在还没发现。
<?xml version="1.0" encoding="UTF-8" ?> <schema name="example" version="1.5"> <field name="_version_" type="long" indexed="true" stored="true"/> <field name="_id" type="string" indexed="true" stored="true" required="true" multiValued="false" /> <field name="body" type="string" indexed="true" stored="true"/> <field name="title" type="string" indexed="true" stored="true" multiValued="true"/> <field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/> <uniqueKey>_id</uniqueKey> <defaultSearchField>title</defaultSearchField> <solrQueryParser defaultOperator="OR"/> <fieldType name="string" class="solr.StrField" sortMissingLast="true" /> <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/> <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" /> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.StandardTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" /> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldType> </schema> |
mongod --replSet myDevReplSet --smallfiles
初始化:rs.initiate()
E:\Users\liuzhijun\workspace\mongo-connector\mongo_connector\doc_managers>mongo-connector -m localhost:27017 -t http://localhost:8983/solr/collection2 -n s_soccer.person -u id -d ./solr_doc_manager.py
注意:mongodb通常使用_id作为uniquekey,而Solrmore使用id作为uniquekey,如果不做处理,索引文件时将会失败,有两种方式来处理这个问题:
--unique-key=id到mongo-connector,Mongo Connector 就可以翻译把_id转换到id。<uniqueKey>id<uniqueKey>
替换成
<uniqueKey>_id</uniqueKey>
同时还要定义一个_id的字段:
<field name="_id" type="string" indexed="true" stored="true" />
2014-06-18 12:30:36,648 - ERROR - OplogThread: Last entry no longer in oplog cannot recover! Collection(Database(MongoClient(‘localhost‘, 27017), u‘local‘), u‘oplog.rs‘)
清空E:\Users\liuzhijun\workspace\mongo-connector\mongo_connector\doc_managers\config.txt中的内容,需要删除索引目录下的文件重新启动
测试
mongodb中的数据变化都会同步到solr中去。
