Hey guys I'm trying to save the following class to my collection on Firebase.
public class Review {
private String username;
private String comment;
private int grade;
private String gender;
private LocalDateTime timestamp;
}
However when I use Postman to send the request, I get the following error:
2021-12-19 23:53:01.652 ERROR 3348 --- [nio-9999-exec-4] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.reflect.InaccessibleObjectException: Unable to make private java.time.chrono.IsoChronology() accessible: module java.base does not "opens java.time.chrono" to unnamed module @4e268090] with root cause

It's invoked when I call the following method (to set the document in Firestore):
dbFirestore.collection("shops").document(shop.getId()).set(shop);
I have a list of Review for every Shop so after adding a new Review I update the same Shop.
My guess is that there's a problem with Firestore processing the LocalDateTime variable. Any solutions to this error or an alternative way of storing a timestamp in Firestore?
CodePudding user response：
I’m not sure if this is the root of your problem, but it may be.
LocalDateTime is not a timestamp
LocalDateTime is exactly the wrong data type for a timestamp. That class represents a date with time-of-day but lacks the context of a time zone or offset from UTC.
For a moment as seen in UTC, use Instant.
For a moment as seen in a time zone, use ZonedDateTime.
For a moment as seen with an offset from UTC, use OffsetDateTime.
To communicate a moment with a SQL-oriented database, use OffsetDateTime.
