今日完成：solrJ实现增删改查的功能全部完成，下载gitlab,使用java分别读取CDEF盘的文件名并显示在后台，继续看网课学习solr 明日计划：试着建立一个数据库，将所有读取的文件名导入到数据库之中，完善solrJ和maven功能的使用，修改查询的页面 心得体会：网课有很多资料不分享导致查询资料很困难，这时候要学会自主筛选资料 来源： https://www.cnblogs.com/hanswang121/p/11414672.html

How can I get a list of all the cores in a solr server using SolrJ

由 拥有回忆 提交于 2019-11-28 08:25:00
We are using Solr for our searches, and sharding the data across several cores. We have one core per week of data, so we are dynamically creating and deleting cores each week. How can I query a solr server for a list of all its cores? The JavaDoc says I can use coreAdminHandler.getCoreContainer().getCoreNames() , but I'm not sure how to build a coreAdminHandler object. A request to http://localhost:8983/solr/admin/cores?action=STATUS (replace your own host/port of course) will return all cores. Using SolrJ as you asked, here is how I did: // Solr server instance CommonsHttpSolrServer

Solr running on Https - SolrJ Connection issue

由 感情迁移 提交于 2019-11-28 08:05:42
问题 Am running Solr in Https(8443) port on top of tomcat, How can i access that solr using solrj client, I can see only CommonsHttpSolrServer is availble, Please suggest is there any way to access the https port enabled solr using SolrJ?. 回答1: Solrj internally uses Apache Http Client. When using CommonsHttpSolrServer it will create one & use it, if you are not providing it with one. In this case since you need support for SSL you could provide your own SSL configured HttpClient to

Call Solr asynchronous from Play Framework

问题 I have created a Play 2.1 Scala application. I am uncertain what's the best way to call Solr from a Play application: There is no Solr module for Play 2. AFAIK all Solr-APIs like SolrJ are blocking. I could wrap a SolrJ call into a Future , but this will also block a thread, correct? Should I use the play.api.libs.ws.WS library to call Solr and use Plays JSON support to extract the result (like in the example below) or is there any easier/faster way? val solrQuery: Future[play.api.libs.ws

How to perform a remote Solr core backup through SolrJ client?

由 雨燕双飞 提交于 2019-11-28 05:33:26
问题 I want to write a java client based on SolrJ which pulls the entire core data to a file from a remote Solr server. Later on I want to replay this file to another remote Solr server core. What is the best method to implement this functionality? 回答1: It's now possible with latest Solr versions. To achieve backup on one Solr Server and restore on another one needs to do the following: For each Solr installation in solr.xml setup backup repository to point to some shared drive. For example, one
