Question

我想将Storm拓扑与SolrJ集成，但我收到此错误

thread "main" java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET
at org.apache.http.impl.client.DefaultHttpClient.setDefaultHttpParams(DefaultHttpClient.java:181)

它应该是依赖性问题，但我检查了我的类路径，并且有正确版本的http-client和http-core，没有重复。

对于这个问题已经有this个问题了，但是没有其他信息只是他解决了它。

上述帖子对版本有评论。我可以看到你正在使用solrj 5.它是最新的一个。索引5中索引数据的方式有很多变化。请粘贴您正在使用的代码段。
