LocalDateTime mapped to Oracle DATE, but not to H2 DATE - oracle

Question

Let's say I have JPA #Embeddable:
#Embeddable
public class SpecificationValidity {
#Column(name = "VALID_FROM", nullable = false)
private final LocalDateTime validFrom;
#Column(name = "VALID_TO")
private final LocalDateTime validTo;
}
SQL table contains columns VALID_FROM and VALID_TO and is declared using liquibase changeset as follows:
<column name="VALID_FROM" type="date">
<constraints nullable="false"/>
</column>
<column name="VALID_TO" type="date"/>
When I run this code against Oracle database, everything works.
When I run it against H2 database, Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column type encountered in column [valid_from] in table [specification]; found [date (Types#DATE)], but expecting [timestamp (Types#TIMESTAMP)]
Why is it?
Is it possible to have consistent mapping for both dbms?

Answer 1

I assume you use Hibernate(from your exception message). Since you are using java 8 or above, you might need to add this to your dependency for hibernate 5.0.x.
<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-java8 -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-java8</artifactId>
<version>5.3.7.Final</version>
</dependency>
This helps to convert to and fro from Java 8 types to JPA known types. In this case it allows LocalDateTime LocalDate and Instant etc.,
I'm putting out the mapping that comes along(referred in the article as well).
A reference article : Hibernate + java 8 datetime
P.S : For Hibernate 5.2x and above no need for this explicit dependency.
