新手问题 Connection refused 难题！！

rails 新手，最近在练习 rails 开发，跟着 guide 做，遇到一个问题，现在有一个资源叫 post，当创建一个 post 时，报了一个特别奇怪的错误 Errno::ECONNREFUSED in PostsController#create

上 google 查了一下，确实发现了不少跟我一样的错误，这个错误是由于一个 gem 包 sunspot 导致的， 按照上图的指示执行 又出了下面错误 这就很奇怪，我今天是因为需要给每一个 post 加一个 user 的引用 如图 之后 才报了 Connection refused 错误，之前一直没问题。真的不知道问题出在哪了，希望各位过来人能给予帮助

以下是 Framework Trace

日志不是已经告诉得很清楚了吗？你需要有 java 环境才能运行 solr

#1 楼 @qhwa 但是我之前一直没有遇到需要 Java 环境的问题啊，本机之前一直没装 Java 环境，运行的好好的，就是昨晚改了点东西之后才出现这个问题，所以一直很纳闷。
