将我自己的类添加到solr 5.3.1

Question

我想将我的基于solr的应用程序从Solr 4更新到Solr 5.3.1

我刚刚发现，因为Solr 5.2不再可能将Solr作为WebApp运行。因此，不是将项目（使用solr作为Maven依赖项）打包为WAR并使用单独的Jetty运行它，现在我需要将我的源代码放入Solr。但我怎么能这样做？

我试图将我的项目打包为JAR并将其放在/solr-5.3.1/contrib/mySearchApplication/lib/mysearch.jar文件夹中，并在solrconfig.xml <lib dir="${solr.install.dir:../../../..}/contrib/mySearchApplication/lib" regex=".*\.jar" />中添加了此路径，但是当我尝试运行Solr时，它仍然无法找到我的类，例如我自定义的令牌过滤器

那么如何将我的java类添加到solr？

我收到此错误消息：

Answer 1

您可以将sharedLib参数添加到solr.xml文件中。

此参数指定将在所有核心之间共享的公共库目录的路径。此目录中的任何JAR文件都将添加到Solr插件的搜索路径中。此路径相对于顶级容器的Solr Home。

我就是这样做的。

<?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>

在Windows中，solr.xml可能如下所示：

<solr>
  <str name='sharedLib'>F:\solr_deployment\solr-7.6.0\contrib\analysis-extras\lucene-libs</str>

  <solrcloud>

    <str name="host">${host:}</str>
    <int name="hostPort">${jetty.port:8983}</int>
    <str name="hostContext">${hostContext:solr}</str>

    <bool name="genericCoreNodeNames">${genericCoreNodeNames:true}</bool>

    <int name="zkClientTimeout">${zkClientTimeout:30000}</int>
    <int name="distribUpdateSoTimeout">${distribUpdateSoTimeout:600000}</int>
    <int name="distribUpdateConnTimeout">${distribUpdateConnTimeout:60000}</int>
    <str name="zkCredentialsProvider">${zkCredentialsProvider:org.apache.solr.common.cloud.DefaultZkCredentialsProvider}</str>
    <str name="zkACLProvider">${zkACLProvider:org.apache.solr.common.cloud.DefaultZkACLProvider}</str>

  </solrcloud>

  <shardHandlerFactory name="shardHandlerFactory"
    class="HttpShardHandlerFactory">
    <int name="socketTimeout">${socketTimeout:600000}</int>
    <int name="connTimeout">${connTimeout:60000}</int>
  </shardHandlerFactory>

</solr>

或者，可以在solrconfig.xml文件中使用此文件：

<config>
        <luceneMatchVersion>7.6.0</luceneMatchVersion>

        <lib dir="${solr.install.dir:../../../..}/contrib/extraction/lib" regex=".*\.jar" />
        <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-\d.*\.jar" />

        <lib dir="${solr.install.dir:../../../..}/contrib/clustering/lib/" regex=".*\.jar" />
        <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-clustering-\d.*\.jar" />

        <lib dir="${solr.install.dir:../../../..}/contrib/langid/lib/" regex=".*\.jar" />
        <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-langid-\d.*\.jar" />

        <lib dir="${solr.install.dir:../../../..}/contrib/velocity/lib" regex=".*\.jar" />
        <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-velocity-\d.*\.jar" />

        <lib dir="${solr.install.dir:../../../..}/contrib/analysis-extras/lucene-libs" regex=".*\.jar" />
        <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-analysis-\d.*\.jar" />
...
</config>
