你可以建议我，我做错了吗

谢谢Perikli，但它已经整理好了。

代码如下：

SolrServer solrServer = new HttpSolrServer("http://localhost:8983/solr");

QueryResponse qResponse = solrServer.query(queryForFecthing);

实际上在创建QueryResponse qResponse的对象时遇到了异常，我认为这是因为我作为参数传递的查询（即上面是＆＃39; queryForFecthing < /强>＆＃39）

。
但这是错误的假设，实际上是因为传递了无效的网址在创建SolrServer的对象（即 solrServer ）
期间

Solrj查询响应
