加入我自己的类来SOLR 5.3.1

Question

我想更新从Solr的4我的Solr基于应用到Solr 5.3.1

我才发现，因为Solr的5.2不再可能运行Solr的作为Web应用程序。 因此，现在我需要将我的源代码放入Solr中，而不是将项目打包为WAR，并将其与单独的Jetty一起运行。 但我该怎么做？

我想我的打包项目作为一个JAR文件，并把它夹在/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" />这条道路，但是当我尝试运行的Solr仍然无法找到我的职业，例如我的自定义令牌过滤器

那么如何添加我的java类到solr？

我收到此错误信息：

您可以添加sharedLib参数到solr.xml文件。

此参数指定共享库目录的路径， 将在所有核心间共享。此目录中的任何JAR文件将被添加到Solr插件的搜索路径中。此路径相对于顶层容器的Solr Home的 。

这是我做的。

<?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>
