我试图使用SolrJ使用Solr索引一些数据。但我有这个错误，我无法解决。 

Exception in thread "main" org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://localhost:8983/solr/#/corename: Expected mime type application/octet-stream but got text/html. <html>

这是我连接的方式（我在当地）

SolrClient client = new HttpSolrClient.Builder("http://localhost:8983/solr/#/corename").build();
当我删除“＃”时它抛出一个NullPointerException。我真的可以理解为什么我有这些错误。请在下面找到错误：

我已经用这个索引努力了一个星期......

答案 0 :(得分：0)

正如Cliff提示的那样，URL的#部分是本地锚点（仅由浏览器解释），不应该是URL的一部分。该URL仅供用于通过常规浏览器访问Solr的Web界面使用。

核心/集合的直接URL是：

http://localhost:8983/solr/corename

..但是SolrJ使用（并且在您链接的示例中显示的是）没有核心/集合名称的URL：

final String solrUrl = "http://localhost:8983/solr";
return new HttpSolrClient.Builder(solrUrl)
    .withConnectionTimeout(10000)
    .withSocketTimeout(60000)
    .build();

..然后在添加时提供核心/集合名称：

final UpdateResponse updateResponse = client.add("techproducts", doc);
