'AttributeConverter and explicit Type cannot be applied to same attribute' using LocalDateTime

Question

I am using a ZonedDateTime currently using Spring Boot 1.3.1 with JPA and Hibernate using jadira:

@Type(type = "org.jadira.usertype.dateandtime.threeten.PersistentZonedDateTime")
private ZonedDateTime startTime;

This works fine. However, I would like to use LocalDateTime now instead. I changed the code to:

@Type(type = "org.jadira.usertype.dateandtime.threeten.PersistentLocalDateTime")
private LocalDateTime startTime;

By doing so, I get the following exception:

Answer 1

Do like the message says and remove the custom annotation, so then it (presumably) will pick up the JPA 2.1 AttributeConverter that has probably been defined as "autoApply"
