solr6.5.1（2）定时增量更新

近期电商项目需要用到solr服务，之前对solr了解不多，最近主要做了安装solr，刚开始用docker安装，后续感觉docker维护起来比较费劲，原本直接丢进Tomcat就能启动了，何必搞那么麻烦。废话不多，记录下今天解决当前最新版本6.5.1的定时增量更新问题

1.依赖jar包

官方给的jar比较老了，新版本的实例化更新了方式，这个jar的源码也需要更新了，主要调整方式主要参考了博客：http://blog.csdn.net/yxue1118/article/details/51800145
我更改的jar包在此下载：

2.配置文件

在solr_home下新建conf文件夹，将dataimport.properties放在该目录下
dataimport.properties内容如下：

# dataimport.properties example
#
# From this example, copy everything bellow "dataimport scheduler properties" to your
#   dataimport.properties file and then change params to fit your needs
#
# IMPORTANT:
# Regardless of whether you have single or multiple-core Solr,
#   use dataimport.properties located in your solr.home/conf (NOT solr.home/core/conf)
# For more info and context see here:
# http://wiki.apache.org/solr/DataImportHandler#dataimport.properties_example

#  to sync or not to sync
#  1 - active; anything else - inactive
syncEnabled=1

#  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=solr-test

#  solr server name or IP address
#  [defaults to localhost if empty]
server=localhost

#  solr server port
#  [defaults to 80 if empty]
port=8080

#  application name/context
#  [defaults to current ServletContextListener's context (app) name]
webapp=solr

#  URL params [mandatory]
#  remainder of URL
##params=/select?qt=/dataimport&command=delta-import&clean=false&commit=true
params=/dataimport?command=delta-import&clean=false&commit=true&optimize=false&wt=json&indent=true&entity=data&verbose=false&debug=false

#  schedule interval
#  number of minutes between two runs
#  [defaults to 30 if empty]
interval=10

3.web.xml增加监听

将以下代码添加进web.xml:

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

4.重启solr项目，查看日志情况，若日志输出正常，则配置无误
