Невозможно включить сжатие Jetty при использовании Solr 4.4

Question

Я пытаюсь запустить Solr 4.4.0, используя дистрибутив Jetty, который поставляется вместе с ним. Я хочу включить сжатие GZip на Jetty, чтобы уменьшить сетевой трафик. Я пытаюсь запустить «пример» по умолчанию, который предоставляется в дистрибутиве. Я редактировал файл примера/Solr-WebApp/WebApp/WEB-INF/web.xml добавить следующие строки в:

<filter> 
<filter-name>GzipFilter</filter-name> 
<filter-class>org.eclipse.jetty.servlets.GzipFilter</filter-class> 
<init-param> 
    <param-name>mimeTypes</param-name> 
    <param-value>text/html,text/plain,text/xml,application/xhtml+xml,text/css,application/javascript,image/svg+xml</param-value> 
</init-param> 
</filter> 
<filter-mapping> 
    <filter-name>GzipFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping> 

Однако, во время запуска, я получаю следующее исключение:

Сервер Solr запускается, и я также могу запросить Solr в обычном режиме. Но результаты не получают gzip. Может ли кто-нибудь сказать мне, что здесь происходит не так?

Answer 1

Я подозреваю, что вам нужно добавить артефакт приставки-сервлетов в конфигурацию запуска для solr. Я не знаю, как Solr запускается, но если они используют start.ini файл, то вы должны быть в состоянии добавить что-то вроде:

OPTIONS = пристани-сервлеты
