Question

大家好我是弹性搜索的新手，我正试图处理我目前到达的错误。所以我只想要一个字段值，例如＆＃34; xmldata＆＃34;我在xml文件的早期进程中添加了它。 xml被格式化为json并成功加载到我的ES-Server，json文件是正确的。

这是我的代码：

        Client client = TransportClient.builder().build()
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    // GetResponse response = client.prepareGet("store", "xml",
    // xsdid).setFields("xmldata").execute().actionGet();
    GetResponse response = client.prepareGet().setIndex("store").setType("xml").setId(xsdid).setFields("xml").execute().actionGet();

    String id = (String) response.getSource().get("xml");

我正在关注错误：

MapperParsingException [无法解析];嵌套：IllegalArgumentException [格式错误的内容，解析后发现额外数据：START_OBJECT];

如果您需要，我的XML看起来像这样：

    <?xml version="1.0" encoding="UTF-8"?><XmlDoc><FunctionResult result="success"><Message>Processed Correct!</Message></FunctionResult>
<billing>
<billing_id>571</billing_id>

请帮帮我！感谢

Answer 1

Client client = TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    GetResponse getResponse = client.prepareGet("database", "xsd", xsdid).execute().actionGet();

    Map<String, Object> source = getResponse.getSource();

像这样我得到了完整的json文件

但是有没有更好的方法来获得单一的（xmldata）？
