< 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。
