我正在尝试启动并运行solr索引，但现在我卡住了。我猜SolrDispatchFilter有什么用，但是什么？我唯一的例外是来自catalina.out：

日志localhost.yyyy-mm-dd.log也不例外。
我试图将solrconfig.xml中的requestDispatcher handleSelect =“true”设置为true和false并将其注释掉，但没有任何帮助。
有什么想法吗？
编辑：为了将来参考，我有一个损坏的索引，不确定这个异常是如何链接的，但无论如何通过修复索引解决了。

我今天遇到了这个问题。我正在使用Solr 4.10.2
此页面很有帮助。我在Solr日志文件中收到类似的错误消息
我删除了/solr.4.10.2/blah_blah/solr/core_name/data/index/中的所有文件。将blah_blah和core_name替换为您拥有的目录名称和核心名称。然后，我重新启动了Solr。然后，我使用完整索引选项对导致错误的核心执行了数据导入。
