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。
