The editor below will share with you an example of how to sort single-layer json in alphabetical order by key. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor and take a look.

I recently encountered a problem when working on a bank project: the bank’s signature data must be arranged in order, and then spliced ​​together to add the signature. At this time, I encountered a problem, how to implement it The key-value in the JSONObject object is sorted according to key;

The implementation code is as follows:

<span style="font-size:18px;">import java.util.Iterator; 
import java.util.SortedMap; 
import java.util.TreeMap; 
import net.sf.json.JSONObject; 
public class JsonUtils { 
 /** 
  * 对单层json进行key字母排序 
  * @param json 
  * @return 
  */ 
 public static JSONObject getSortJson(JSONObject json){ 
  Iterator<String> iteratorKeys = json.keys(); 
  SortedMap map = new TreeMap(); 
  while (iteratorKeys.hasNext()) { 
    String key = iteratorKeys.next().toString(); 
    String vlaue = json.optString(key); 
    map.put(key, vlaue); 
  } 
  JSONObject json2 = JSONObject.fromObject(map); 
  return json2; 
 } 
public static void main(String[] args){ 
  JSONObject json = new JSONObject(); 
  json.put("cc", "cc"); 
  json.put("bb", "bb"); 
  json.put("ee", "ee"); 
  json.put("aa", "aa"); 
  json.put("ba", "ba"); 
  json.put("bd", "bd"); 
  System.out.println(getSortJson(json).toString()); 
 } 
}</span>
Copy after login

The above is what I compiled for everyone. I hope that in the future It will be helpful to everyone.
