Java Spring Boot - Get date and time as string instead of nested

I was handed a Java Spring Boot application and I only need to change one thing. Among other data in the json data I handle, I have the following:

"valueSetAt":{
   "dateTime":{
      "date":{
         "year":2023,
         "month":5,
         "day":2
      },
      "time":{
         "hour":13,
         "minute":1,
         "second":36,
         "nano":335000000
      }
   },
   "offset":{
      "totalSeconds":0
   },
   "zone":{
      "id":"UTC"
   }
}

I need to convert this form of date and time to datetime of the format

"startTime":
   "2023-03-31T13:00:00.000Z"

The problem is, I can't do anything before the transformation because this wrong format is coming from an API to which I can't see or change anything. The developers from the API said that the transfomation occured when they processed the data to json. Essentialy I think that what I need is to above date and time to convert from ZonedDateTime to a String?

Seems there're already answer for your question.

It's not clear whether you're consumer or producer of those values, but on case of both, you can handle it by specifiyng getter and setter with appropriate annotations on it:

public class DtoObject {
  private ZonedDateTime dateTimeField;

  // Used during serialization
  @JsonProperty("startTime")
  @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ")
  public ZonedDateTime getStartTime() {
    return dateTimeField;
  }

  // Used during deserialization
  // eg. @JsonFormat(pattern = "yyyy-MM-dd") 
  public void setDateTimeField(ZonedDateTime dateTimeField) {
    this.dateTimeField = dateTimeField;
  }
}
