solr定時增量索引

參考：官方文檔,http://wiki.apache.org/solr/DataImportHandler#Scheduling

googlecode 找到：https://code.google.com/p/solr-dataimport-scheduler/

1.復制solr-4.2.11\solr-4.2.1\dist目錄下solr-dataimporthandler-4.2.1.jar 和solr-dataimporthandler-extras-4.2.1.jar到

D:\program\tomcat6\webapps\solr\WEB-INF\lib目錄下

2.從https://code.google.com/p/solr-dataimport-scheduler/downloads/list 下載apache-solr-dataimportscheduler-1.0-with-source.jar到

D:\program\tomcat6\webapps\solr\WEB-INF\lib目錄下

3.取出apache-solr-dataimportscheduler-1.0-with-source.jar內的dataimport.properties到D:\program\tomcat6\solrapp\solr\conf

conf文件夾是沒有的，要新建

4.修改D:\program\tomcat6\webapps\solr\WEB-INF\web.xml,加入

     <listener>
             <listener-class>org.apache.solr.handler.dataimport.scheduler.ApplicationListener</listener-class>
   </listener>

5.修改dataimport.properties內容：

#  which cores to schedule
#  in a multi-core environment you can decide which cores you want syncronized
#  leave empty or comment it out if using single-core deployment
#syncCores=game,resource

#  URL params [mandatory]
#  remainder of URL

#  schedule interval
#  number of minutes between two runs
#  [defaults to 30 if empty]
interval=1

#  重做索引的時間間隔，單位分鍾，默認7200，即1天; 
#  為空,為0,或者注釋掉:表示永不重做索引
reBuildIndexInterval=2

#  重做索引的參數
reBuildIndexParams=/dataimport?command=full-import&clean=true&commit=true

#  重做索引時間間隔的計時開始時間，第一次真正執行的時間=reBuildIndexBeginTime+reBuildIndexInterval*60*1000；
#  兩種格式：2012-04-11 03:10:00 或者  03:10:00，后一種會自動補全日期部分為服務啟動時的日期
reBuildIndexBeginTime=03:10:00
