我已收到此响应 SOLR 并希望从中获取 JSONObject SOlr 文档。请帮助我如何解析此响应。

您提到的字符串是一个 json 字符串（json 是 Javascript Object Notation）。尝试使用 java-json lib 对其进行解码。这是一个例子。

我发现这篇文章很有用。虽然问这个问题的时候已经很成熟了，但它也可能对其他人有所帮助，因为我遇到了同样的问题。我使用 Google API for JSON - GSON 解决了​​这个问题。

Solr 给出的响应不是 JSON 格式。我们需要转换它。我从 solr 检索响应并将其转换为 json 对象。

最初，我的回应是：

   {docs=[SolrDocument{id=1, uuid=7fe08f79-e184-454d-908f-08b32583a822, packName=Workflow Logger-Pack, packDescription=Workflow Logger-Pack, packAuthor=NetApp, packVersion=1.0.0, packDate=May 22, 2014, 3:10 pm, entityName=[Workflow Logger, Wait, Logging cmd, Test cmd for multiple Parameter Types], entityDescription=[Workflow Logger, Wait Command, Logging command, Test cmd for multiple Parameter Types], entityType=[Workflow, Command, Command, Command], _version_=1468794552324194304}, SolrDocument{id=2, uuid=7fe08f79-e184-454d-908f-08b32583a822, packName=Workflow Logger-Pack New, packDescription=Workflow Logger-Pack, packAuthor=NetApp, packVersion=2.0.0, packDate=May 22, 2014, 3:13 pm, entityName=[Workflow Logger, Wait, Logging cmd, Test cmd for multiple Parameter Types], entityDescription=[Workflow Logger, Wait Command, Logging command, Test cmd for multiple Parameter Types], entityType=[Workflow, Command, Command, Command], _version_=1468794760693022720}, SolrDocument{id=3, uuid=7fe08f79-e184-454d-908f-08b32583a822, packName=Workflow Logger-Packs updated, packDescription=Workflow Logger-Pack, packAuthor=NetApp, packVersion=3.0.0, packDate=May 22, 2014, 3:32 pm, entityName=[Workflow Logger, Wait, Logging cmd, Test cmd for multiple Parameter Types], entityDescription=[Workflow Logger, Wait Command, Logging command, Test cmd for multiple Parameter Types], entityType=[Workflow, Command, Command, Command], _version_=1468795898385399808}, SolrDocument{id=5, uuid=7fe08f79-e184-454d-908f-08b32583a822, packName=Workflow Logger-Pack New, packDescription=Workflow Logger-Pack, packAuthor=NetApp, packVersion=2.0.0, packDate=June 17, 2014, 7:02 am, entityName=[Workflow Logger, Wait, Logging cmd, Test cmd for multiple Parameter Types], entityDescription=[Workflow Logger, Wait Command, Logging command, Test cmd for multiple Parameter Types], entityType=[Workflow, Command, Command, Command], _version_=1471140110510587904}]}

我的代码：

 HttpSolrServer server= new HttpSolrServer("http://localhost:8983/solr");
        server.setParser(new XMLResponseParser());

        Gson gson= new Gson();

        SolrQuery solrQuery = new SolrQuery();
        solrQuery.setQuery("*:*");

        solrQuery.setHighlight(true);

        solrQuery.setHighlightRequireFieldMatch(true);
        QueryResponse response= server.query(solrQuery);
        SolrDocumentList docs = response.getResults();

        String res= gson.toJson(docs);
        System.out.println(res);

现在，它被转换为 JSON，如下所示：

您需要使用哈希映射来制作 JSONObject ，solrj 目前不支持 json 格式作为输出
