部分代码：
String urlString = "http://localhost:8080/solr/core0";
SolrServer solr = new HttpSolrServer(urlString);
ContentStreamUpdateRequest up = new ContentStreamUpdateRequest("/update/extract");
是因为我用的： core0 （这个在当前的solr目录下是不存在的）,已经被删除了。改为存在collection1 就正常通过。
所以有这样的错误一般是配置错误，或者操作的core核心不存在，或者没有配置对应的handler。都是路径错误，或者用法上的错误。
