Talend 提取 Json 字符串作为键值数组
您好，我使用 Talend ESB 7.2，并尝试使用 tRest Response
\n\n我已经使用 tJsonExtractField 提取 Json \n
在“metas”字段中，我有另一个 json 字符串，我尝试将此字符串提取为数组（具有键值关联）。
\n\n元字段示例

\n\n我给你举了 2000 个项目的 2 个例子：

\n\n{ \n "meta":[ \n { \n "id":"482f75dd-a8e4-4f5c-80f0-85b5a7eeb340",\n "value":[ \n "ind\xc3\xa9termin\xc3\xa9"\n ]\n },\n { \n "id":"d8cac586-2d64-4fe6-bdf4-91a5bac3541e",\n "value":[ \n "Id system"\n ]\n }\n ]\n}\n感谢帮助
\n在tLibraryLoad组件中加载json-simple jar 并导入所需的库（在高级设置中）。
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
在tJavaFlex组件中，您可以处理数据输入（如下所示onlyMet）
JSONObject job = new JSONObject();
JSONParser parser = new JSONParser();
try {
//-- Parsing et prepare result
List<JSONObject> resultList = new ArrayList<>();
JSONObject jsonObjects = (JSONObject) parser.parse((String)onlyMet.metas);
jsonObjects.keySet().parallelStream().forEach(entry -> {
JSONObject rjo = new JSONObject();
rjo.put("id", entry);
rjo.put("value", jsonObjects.get(entry));
// System.out.printf("- meta %s : %s \n", entry, jsonObjects.get(entry)); // for debug if needed
resultList.add(rjo);
});
// Outpout the result
onlyOut.metas = resultList.toString();
} catch (final Exception e){
e.printStackTrace();
}
