Date format changed in Payara 5 (Long does not work anymore ) — org.eclipse.yasson.YassonProperties#ZERO_TIME_PARSE_DEFAULTING

问题

Using Payara 4.174 and receive in backend the date as a long, for example 1540545780000. Now, I upgraded to Payara version 5.

public User {
   String name;
   Date birthdate;
}

@POST
@Path("/user/)
public void createUser(User user) {
   ...
}

json call 
{ 
   name: "name",
   birthdate: 1540545780000
}

Now The call brakes with the following error:

Caused by: javax.json.bind.JsonbException: Error parsing class java.util.Date from value: 1540545780000. Check your @JsonbDateFormat has all time units for class java.util.Date type, or consider using org.eclipse.yasson.YassonProperties#ZERO_TIME_PARSE_DEFAULTING.

Jonathan is partly right. You don't have to write a custom DateTypeDeserializer to solve your issue. However, as the error message describes, you can annotate your Field with @JsonbDateFormat to resolve your error, you have to make sure it has all time units.

Here is an example:

public User {
   String name;
   @JsonbDateFormat(value = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
   Date birthdate;
}

This is because Payara 5 switched to using Yasson as its JsonB provider, which does not contain a mapper for long to java.util.Date (see here). You have to write your own version to map a number to Date format.
