主文件你可以試試下面的代碼用於獲取$ REF值

import org.json.simple.JSONArray; 
import org.json.simple.JSONObject; 
import org.json.simple.parser.JSONParser; 
public class Test{ 

    public static void main(String[] args) { 
     JSONParser parser = new JSONParser(); 

     try { 

      Object obj = parser.parse(new FileReader(
        "File location")); 
      JSONObject jsonObject = (JSONObject) obj; 
      JSONObject properties = (JSONObject) jsonObject.get("properties"); 
      JSONObject triggerTime = (JSONObject) properties.get("triggerTime"); 
      String ref = (String) triggerTime.get("$ref");//You can load this file to a map if required. 
      System.out.println(ref); 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
} 

輸出

abc.def.xyz。 1.json＃
