如何使用 Java 将当前时间作为参数传递给 Json 有效负载？

Question

In I am passing a Json payload as a string using Java. But when i am trying to send a variable JsonPathException.

I have the following code:

public class Payloads {
    
    
    static String lowerBound;
    static String upperBound;
    
    public static void getTime() {
                    
        lowerBound = DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(LocalDateTime.now().minusMinutes(2));
        upperBound = DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(LocalDateTime.now());
    }
    
    
    public static String SprinklrPayload() {
        System.out.println("Lower Bound>>>>>>>>>>>>>>>>>>>>> "+lowerBound+ "<<<<<<<<<<<<<<Upper Bound>>>>>>>>> "+upperBound);
        
        return "{\r\n"
                + "\r\n"
                + "  \"predicateParams\": {\r\n"
                + "\r\n"
                + "    \"type\":\"dam:Asset\",\r\n"
                + "\r\n"
                + "    \"p.offset\": \"0\",\r\n"
                + "\r\n"
                + "    \"p.limit\": \"-1\"\r\n"
                + "\r\n"
                + "  },\"dateParams\": {\r\n"
                + "\r\n"
                + "  \"group.1_daterange.lowerBound\":\'"+lowerBound+"'\",\r\n"
                + "\r\n"
                + "  \"group.1_daterange.upperBound\":\'"+upperBound+"'\"\r\n"
                + "\r\n"
                + "  } \r\n"
                + "\r\n"
                + "}";
        
    }

}

How can i pass the varibles lowerBound and upeerBound into json body.

I would suggest you use on of the various libraries for parsing/working/editing JSONs in java. Personally I am using Jackson https://www.baeldung.com/jackson
