Solr 当我想添加文档时出现错误 404

如何解决Solr 当我想添加文档时出现错误 404

可以在浏览器中显示solr仪表板

http://localhost:8984/solr/#/

因此，当我想添加对象“文档”时，我在控制台中显示此错误：

Exception in thread "main" org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://localhost:8984/solr: Expected mime type application/xml but got text/html. <html>
<head>
<Meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<title>Error 404 Not Found</title>
</head>
<body><h2>HTTP ERROR 404 Not Found</h2>

</table>

我的代码：

        String urlString = "http://localhost:8984/solr/";
        HttpSolrClient solr = new HttpSolrClient.Builder(urlString).build();
        solr.setParser(new XMLResponseParser());

        SolrInputDocument document = new SolrInputDocument();
        document.addField("id","123456");
        document.addField("name","Kenmore dishwasher");
        document.addField("price","599.99");
        solr.add(document);
        solr.commit();

问题所在：

solr.add(document)

告诉我怎么了？
