Question

您好我正在使用elasticsearch java API来更新脚本文档。但我得到的是异常

Exception in thread "main" MapperParsingException[object mapping for [content] tried to parse field [content] as object, but found a concrete value]

以下是ES

中的现有文件

{
  "_index": "index1",
  "_type": "type1",
  "_id": "1",
  "_version": 8,
  "found": true,
  "_source": {
    "content": {
      "contentId": 1,
      "metadata": {
        "title": "content one",
        "duration": 4500
      }
    },
    "custom": {
      "field1": "value1"
    }
  }
}

我想更新“内容”字段，如下所示

"content": {
      "contentId": 1,
      "metadata": {
        "duration": 900
      }
    }

当我使用REST调用（localhost：9200 / index1 / type1 / 1 / _update）进行更新时，它工作正常。我在java API prepareUpdate中遇到错误。

我有3个java类。 DTO类有Content对象 Content类具有Metadata对象和contentId 元数据类具有标题（String）和持续时间（long）。

以下是要更新的代码

Map<String, Object> params = new HashMap<>();
params.put("contentScript", dto.toString());
Script s = new Script("ctx._source.content=contentScript",ScriptType.INLINE,null,params);
UpdateResponse resp = client.prepareUpdate("index1", "type1", "1").setScript(s).setScriptedUpsert(true).get();

dto是DTO类的对象，并且相应地设置了值。

请帮忙。

Answer 1

params.put("contentScript", dto.toString());

您正在传递一个预期对象的字符串。以下代码可能有所帮助。

String script = "ctx._source.pete = jsonMap";
Map<String, Object> jsonMap = new ObjectMapper().readValue(json, HashMap.class);
Map<String, Object> params = ImmutableMap.of("jsonMap", jsonMap);
return new Script(script, ScriptService.ScriptType.INLINE, null, params);
