Question

在我的应用程序中，我有太阳黑子solr并且运行得很好，直到几天前。现在突然间，我甚至无法开发我的solr。每次我运行rake sunspot:solr:run时都会抛出此错误：

:INFO:oejw.StandardDescriptorProcessor:NO JSP Support for /solr, did not find org.apache.jasper.servlet.JspServlet
Null identity service, trying login service: null
Finding identity service: null

我没有对我的设置进行任何更改，我已经尝试了this question的建议，但似乎没有任何效果。有谁知道这个错误意味着什么，我该如何解决？

的Gemfile

gem 'sunspot_solr'
gem 'sunspot_rails', github: 'sunspot/sunspot', branch: 'master'

sunspot.yml

production:
  solr:
    hostname: websolr_url
    port: 8983
    log_level: WARNING
    path: /solr/production
    # read_timeout: 2
    # open_timeout: 0.5

development:
  solr:
    hostname: localhost
    port: 8983
    log_level: INFO
    path: /solr/development

test:
  solr:
    hostname: localhost
    port: 8983
    log_level: WARNING
    path: /solr/test

**** **** EDIT

这是我从/solr管理页面获得的错误。我对solr很新，也不知道如何解决这个问题。

Answer 1

这不是由太阳黑子引起的，而是由您的Solr实例的错误配置引起的。 Solr需要JSP支持才能提供其管理页面（哪些库查询以获取有关模式的信息等）。如果管理界面因任何原因而无法使用，这将使图书馆因以上消息而退出。

在调试客户端上的任何内容之前，请确保您可以通过常规浏览器访问/solr（或安装它的位置）。对于你需要转移的捆绑码头important settings in an .ini file。您的应用容器的日志可能会告诉您更多信息（可能您在容器中缺少JSP支持，缺少.jars等）。

Answer 2

最简洁的方法是从cratch开始：

删除整个/solr目录
重新安装
启动solr服务器以重新创建/solr目录
重新索引
添加回来的任何自定义配置

太阳黑子solr没有JSP连接错误
