加入我自己的類來SOLR 5.3.1

Question

我想更新從Solr的4我的Solr基於應用到Solr 5.3.1

我才發現，因爲Solr的5.2不再可能運行Solr的作爲Web應用程序。 因此，現在我需要將我的源代碼放入Solr中，而不是將項目打包爲WAR，並將其與單獨的Jetty一起運行。 但我該怎麼做？

我想我的打包項目作爲一個JAR文件，並把它夾在/solr-5.3.1/contrib/mySearchApplication/lib/mysearch.jar我和solrconfig.xml中添加<lib dir="${solr.install.dir:../../../..}/contrib/mySearchApplication/lib" regex=".*\.jar" />這條道路，但是當我嘗試運行的Solr仍然無法找到我的職業，例如我的自定義令牌過濾器

那麼如何添加我的java類到solr？

我收到此錯誤信息：

您可以添加sharedLib參數到solr.xml文件。

此參數指定共享庫目錄的路徑， 將在所有核心間共享。此目錄中的任何JAR文件將被添加到Solr插件的搜索路徑中。此路徑相對於頂層容器的Solr Home的 。

這是我做的。

<?xml version='1.0' encoding='UTF-8'?> 
<solr> 
     <str name='sharedLib'>/opt/shared-lib</str> 

     <solrcloud> 
      <str name="host">${host:}</str> 
      <int name="hostPort">${hostPort:8080}</int> 
      <str name="hostContext">${hostContext:solr}</str> 
      <int name="zkClientTimeout">${zkClientTimeout:15000}</int> 
      <bool name="genericCoreNodeNames">${genericCoreNodeNames:true}</bool> 
     </solrcloud> 

     <shardHandlerFactory name="shardHandlerFactory" 
      class="HttpShardHandlerFactory"> 
      <int name="socketTimeout">${socketTimeout:0}</int> 
      <int name="connTimeout">${connTimeout:0}</int> 
     </shardHandlerFactory> 

</solr>
