JsonPath字段提取，在Talend 5.5

我有以下JSON字符串，我需要只提取ID場的名單和名場，對於IDS的預期結果將是：JsonPath字段提取，在Talend 5.5

{15124,10287,13766,13568...etc}

而對於名字的預期輸出爲：

{" yoav ([email protected]) - 301519506662355","Inactive (ilan.dayan)","Inactive ([email protected])","Inactive (jonatan.silvester)"..etc}

我嘗試這條道路：$.response.data.*.id，但我得到了我不需要的「時區」鍵內的ID列表。

這是JSON字符串：

什麼jsonpath模式應該我送？

隨着$.response.data.*.id模式，你請求數據節點其中將包括時區 ID下的所有*身份證* S。

使用將是$.response.data.[*].id和$.response.data.[*].name，正確的圖案即選擇所有ID（名稱）值，其是數據節點的直接兄弟姐妹。

下面的代碼片斷將說明的情況下：

public class ResponseService 
{ 
    public static void main(String[] args) 
    { 
    final String OPENING_CURLY = "{"; 
    final String CLOSING_CURLY = "}"; 
    final String COLON = ","; 
    final String QUOTE = "\""; 

    String jsonData; // Load you response json feed. 
    List<Object> ids = JsonPath.read(jsonData, "$.response.data[*].id"); 
    StringBuilder formattedIds = new StringBuilder(OPENING_CURLY); 
    for (Iterator it = ids.iterator(); it.hasNext();) 
    { 
     formattedIds.append(it.next()); 
     if (it.hasNext()) 
     { 
     formattedIds.append(COLON); 
     } 
    } 
    formattedIds.append(CLOSING_CURLY); 
    System.out.println(formattedIds); 

    List<Object> names = JsonPath.read(jsonData, "$.response.data[*].name"); 
    StringBuilder formattedNames = new StringBuilder(OPENING_CURLY); 
    for (Iterator it = names.iterator(); it.hasNext();) 
    { 
     formattedNames.append(QUOTE) 
     .append(it.next()) 
     .append(QUOTE); 
     if (it.hasNext()) 
     { 
     formattedNames.append(COLON); 
     } 
    } 
    formattedNames.append(CLOSING_CURLY); 
    System.out.println(formattedNames); 
    } 
}

上面的代碼將導致下面的輸出：

{15124,10287,13766,13568,13472,13052,13010,13726,15134} 
{" yoav ([email protected]) - 301519506662355","Inactive (ilan.dayan)","Inactive ([email protected])","Inactive (jonatan.silvester)","Inactive (markus.sogova)","Inactive (matan.hamesh)","Inactive (matan.shmone)","Inactive ([email protected])","yoav ([email protected]) - 1388742651379471"}

簡單

方式使用json.org

String str ="yourJsonString"; 
List<String> listOfIds = new ArrayList<String>(); 
JSONObject jsonObject =new JSONObject(str); 
String jsonStr = jsonObject.get("response").toString(); 
JSONObject jsonObj =new JSONObject(jsonStr); 
String jsonS = jsonObj.get("data").toString(); 
JSONArray jsonArray = new JSONArray(jsonS); 
for(int i =0;i<jsonArray.length();i++){ 
    JSONObject object = new JSONObject(jsonArray.get(i).toString()); 
    listOfIds.add(object.get("id").toString()); 
} 
System.out.println(listOfIds);
