Apache Solr 4.8.1定时增量索引

1.需要准备Java jar:
solr-dataimporthandler-4.8.1.jar
solr-dataimporthandler-extras-4.8.1.jar
apache-solr-dataimportscheduler-1.0-with-source.jar

2.将solr-4.8.1\dist目录下solr-dataimporthandler-4.8.1.jar和solr-dataimporthandler-extras-4.8.1.jar复制到\solrconf\server\solr\WEB-INF\lib目录；

3.从https://code.google.com/p/solr-dataimport-scheduler/downloads/list 下载apache-solr-dataimportscheduler-1.0-with-source.jar到\solrconf\server\solr\WEB-INF\lib目录；

4.取出apache-solr-dataimportscheduler-1.0-with-source.jar内的dataimport.properties到\solrconf\server\solr\conf，conf文件夹默认是没有的，需要新建；

5.修改\solrconf\server\solr\WEB-INF\web.xml,加入

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

6.修改dataimport.properties内容：

reBuildIndexBeginTime=03:10:00
