Solrj 查询响应

Question

您好，我正在尝试从 apache solr 获取查询结果。

我正在使用 Solrj jar 借助 QueryResponse class 获取查询结果，但出现以下错误。

异常消息：

执行查询时出错

异常跟踪：

你能告诉我我哪里做错了吗

Answer 1

谢谢佩里克利，但它得到了整理。

代码如下：

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

QueryResponse qResponse = solrServer.query(queryForFecthing);

实际上在创建 QueryResponse 的对象时出现异常，即 qResponse 我认为这是因为我将其作为参数传递的查询（即上面的是 'queryForFecting ').

但这是错误的假设，实际上是因为无效的 url 通过了在为 SolrServer 创建对象期间（即 solrServer ）
