solr-DIH:定时增量索引

参考：官方文档,http://wiki.apache.org/solr/DataImportHandler#Scheduling

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

1.复制solr-4.2.11\solr-4.2.1\dist目录下solr-dataimporthandler-4.2.1.jar 和solr-dataimporthandler-extras-4.2.1.jar到

D:\program\tomcat6\webapps\solr\WEB-INF\lib目录下

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

D:\program\tomcat6\webapps\solr\WEB-INF\lib目录下

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

conf文件夹是没有的，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内容：

#  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

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

#  重做索引的时间间隔，单位分钟，默认7200，即1天;
#  为空,为0,或者注释掉:表示永不重做索引
reBuildIndexInterval=2

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

#  重做索引时间间隔的计时开始时间，第一次真正执行的时间=reBuildIndexBeginTime+reBuildIndexInterval*60*1000；
#  两种格式：2012-04-11 03:10:00 或者  03:10:00，后一种会自动补全日期部分为服务启动时的日期
reBuildIndexBeginTime=03:10:00
