Cassandra Spring No Converter Found Capable of Converting from Type Instant to type Long - spring

Question

Am getting a No converter found capable of converting from type Instant to type Long while using Spring and Cassandra.
I have 2 Instant fields writtenDate (in the object primary key) and hotelAddedDate in the object. However, I do not have any Long fields; thus, I am a little confused.
Does anyone have an idea how to fix this error?

Answer 1

Had to change CassandraType.Name.BIGINT to CassandraType.Name.TIMESTAMP:
In CustomerReviewsByHotelAndLastNameAndFirstName.java:
...
#Column("hotel_added_date")
#CassandraType(type = CassandraType.Name.TIMESTAMP)
private Instant hotelAddedDate;
...
In CustomerReviewsByHotelAndLastNameAndFirstNameId.java:
...
#PrimaryKeyColumn(
name = "written_date",
ordinal = 3,
type = PrimaryKeyType.CLUSTERED
)
#CassandraType(type = CassandraType.Name.TIMESTAMP)
private Instant writtenDate;
...
