Solrj查詢響應

Question

嗨我試圖從Apache解決方案提取查詢結果。

使用Solrj jar我在QueryResponse類的幫助下獲取查詢結果，但我得到以下錯誤。

異常消息：

u能請給我建議，我哪裏做錯了

Answer 1

謝謝Perikli， 但整理出來了。

的代碼如下：

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

QueryResponse qResponse = solrServer.query(queryForFecthing); 

實際上異常得到同時創造的QueryResponse即qResponse對象，我認爲這是因爲其中我傳遞作爲參數的查詢（即按照上述是「queryForFecthing'）。

但它是錯誤的假設，實際上，這是因爲創建對象的過程中傳遞 爲SolrServer（即solrServer）
