How to edit, modify nested JSONObject
提问by eabyshev
Could you help me with this issue please. for example I have JSONEObject
你能帮我解决这个问题吗？例如我有 JSONEObject
{
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"seeds": "12415",
}
}
}
}
For example, I need change "seeds":"12415" to "seeds":"555". I found some solution:
例如，我需要将“种子”：“12415”更改为“种子”：“555”。我找到了一些解决方案：
JSONObject js = new JSONObject(jsonString);
js.getJSONObject("glossary").getJSONObject("GlossDiv").remove("seeds");
js.getJSONObject("glossary").getJSONObject("GlossDiv").put("seeds","555");
So for editing seeds in my version I need first to get "glossary" then "GlossDiv" after I delete "seeds" and put new "seeds" with new value.
因此，为了在我的版本中编辑种子，在删除“种子”并放置具有新值的新“种子”后，我首先需要获取“词汇表”，然后是“GlossDiv”。
Could you help me to find another way to edit? For example: just somemethod(String key,String NewValue).
你能帮我找到另一种编辑方式吗？例如：只是一些方法（字符串键，字符串新值）。

I found solution.
我找到了解决方案。
public static JSONObject setProperty(JSONObject js1, String keys, String valueNew) throws JSONException {
String[] keyMain = keys.split("\.");
for (String keym : keyMain) {
Iterator iterator = js1.keys();
String key = null;
while (iterator.hasNext()) {
key = (String) iterator.next();
if ((js1.optJSONArray(key) == null) && (js1.optJSONObject(key) == null)) {
if ((key.equals(keym))) {
js1.put(key, valueNew);
return js1;
}
}
if (js1.optJSONObject(key) != null) {
if ((key.equals(keym))) {
js1 = js1.getJSONObject(key);
break;
}
}
if (js1.optJSONArray(key) != null) {
JSONArray jArray = js1.getJSONArray(key);
for (int i = 0; i < jArray.length(); i++) {
js1 = jArray.getJSONObject(i);
}
break;
}
}
}
return js1;
}
public static void main(String[] args) throws IOException, JSONException {
FileInputStream inFile = new FileInputStream("/home/ermek/Internship/labs/java/task/test5.json");
byte[] str = new byte[inFile.available()];
inFile.read(str);
String text = new String(str);
JSONObject json = new JSONObject(text);
setProperty(json, "rpc_server_type", "555");
System.out.println(json.toString(4));

You don't need to removebefore calling put. JSONObject#putwill replace any existing value. Simply call
你并不需要remove调用之前put。JSONObject#put将替换任何现有值。只需致电
js.getJSONObject("glossary").getJSONObject("GlossDiv").put("seeds", "555");
But how to get to wanted key for one step?
但是如何一步到位的得到想要的钥匙呢？
You don't. You have a nested object tree. You must go through the full tree to reach your element. There might be a library out there that does this for you, but underneath it all, it will be traversing everything.
你没有。您有一个嵌套的对象树。您必须遍历完整的树才能到达您的元素。可能有一个库可以为您执行此操作，但在这一切之下，它将遍历所有内容。

Update/ edit/modify nested JSON Object and converting String to JSON by using org.json.simple.JSONObject recursive call
使用 org.json.simple.JSONObject 递归调用更新/编辑/修改嵌套的 JSON 对象并将字符串转换为 JSON
JSON Input file
JSON 输入文件
{
"Response": {
"AccountId": "12345",
"CompanyCode": 1,
"CustomerName": "Joseph X. Schmoe",
"EmailAddressList": {
"Response.EmailAddressDTO": {
"AlertOptionList": null,
"ContactMethodSeqNum": 2,
"EmailAddress": null
}
},
"MailingAddress": {
"NonStandard": null,
"Standard": {
"Address": "Example",
"DisplayAddressText": null
}
},
"LastBill": null,
"LastPayment": null
}
}
Code for the converting String to JSON Object and Updating the Nested JSON object value against the specific Key Example: "Address": "Addressxxxxxx",
用于将字符串转换为 JSON 对象并根据特定关键示例更新嵌套 JSON 对象值的代码：“地址”：“Addressxxxxxx”，
public static void main(String[] args) throws IOException {
FileInputStream inFile = new FileInputStream("File_Location");
byte[] str = new byte[inFile.available()];
inFile.read(str);
String string = new String(str);
JSONObject json = JSONEdit.createJSONObject(string);
System.out.println(JSONEdit.replacekeyInJSONObject(json,"Address","Addressxxxxxx"));
}
private static JSONObject replacekeyInJSONObject(JSONObject jsonObject, String jsonKey,
String jsonValue) {
for (Object key : jsonObject.keySet()) {
if (key.equals(jsonKey) && ((jsonObject.get(key) instanceof String)||(jsonObject.get(key) instanceof Number)||jsonObject.get(key) ==null)) {
jsonObject.put(key, jsonValue);
return jsonObject;
} else if (jsonObject.get(key) instanceof JSONObject) {
JSONObject modifiedJsonobject = (JSONObject) jsonObject.get(key);
if (modifiedJsonobject != null) {
replacekeyInJSONObject(modifiedJsonobject, jsonKey, jsonValue);
}
}
}
return jsonObject;
}
private static JSONObject createJSONObject(String jsonString){
JSONObject jsonObject=new JSONObject();
JSONParser jsonParser=new JSONParser();
if ((jsonString != null) && !(jsonString.isEmpty())) {
try {
jsonObject=(JSONObject) jsonParser.parse(jsonString);
} catch (org.json.simple.parser.ParseException e) {
e.printStackTrace();
}
}
return jsonObject;
}
JSON Output:
JSON 输出：
{
"Response": {
"AccountId": "12345",
"CompanyCode": 1,
"CustomerName": "Joseph X. Schmoe",
