JPA 2.1 is a spec that came out before Java 1.8, so doesn't mandate any support for it. Obviously some implementations may support some Java 1.8 features. Some have problems with Java 1.8 bytecode (e.g EclipseLink). I know DataNucleus supports java.time and Java 1.8 since that's the one I use. You'd have to check your implementation for what its support level is.

It has been requested that JPA 2.2 support the java.time types, see this issue <a href="https://java.net/jira/browse/JPA_SPEC-63" rel="noreferrer">https://java.net/jira/browse/JPA_SPEC-63</a>

I am using Java 8, EclipseLink(JPA 2.1), PostgreSQL 9.3 and PostgreSQL Driver -Postgresql-9.2-1002.jdbc4.jar in my project and I can use <code>LocalDateTime</code> variables from the new API with no error, but the data type of the column will be bytea in the database. You can only read it from a Java application as far i know.
However, you can use <code>AttributeConverter</code> to convert these classes to <code>java.sql.Date</code>. I found this code from <a href="https://weblogs.java.net/blog/montanajava/archive/2014/06/17/using-java-8-datetime-classes-jpa" rel="nofollow noreferrer">Java.net</a>

I know that this is an old question but I thought of an alternative solution which might be helpful.

Instead of trying to map the new java.time.* classes to an existing database types, you can leverage @Transient:

<pre><code>@Entity
public class Person {
 private Long id; 
 private Timestamp createdTimestamp;

 @Id
 @GeneratedValue
 public Long getId() { return id; }

 private Timestamp getCreatedTimestamp() {
 return createdTime;
 }

 private void setCreatedTimestamp(final Timestamp ts) {
 this.createdTimestamp = ts;
 }

 @Transient
 public LocalDateTime getCreatedDateTime() {
 return createdTime.getLocalDateTime();
 }

 public void setCreatedDateTime(final LocalDateTime dt) {
 this.createdTime = Timestamp.valueOf(dt);
 }
}
</code></pre>

You work with the public getter/setter methods that use the new Java 8 date/time classes, but behind the scenes the getter/setters work with the legacy date/time classes. When you persist the entity, the legacy date/time property will be persisted but not the new Java 8 property since it's annotated with @Transient.

There are Many approach to do , Also It depends to your frame work :
If your frame work has on field Converter such spring do such:
1-

<pre><code>@DateTimeFormat(pattern = "dd.MM.yyyy - HH:mm")
private Long createdDate;
</code></pre>

here I am using legacy epoch format <a href="https://www.epochconverter.com/" rel="nofollow noreferrer">https://www.epochconverter.com/</a>
epoch is very flexible and accepted format

2- The other ways is to use jpa @PostLoad @PreUpdate @PrePersist

<pre><code>@PostLoad
 public void convert() {
 this.jva8Date= LocalDate.now().plusDays(1);
 }
</code></pre>

or use temp one such 

<pre><code>@Transient
public LocalDateTime getCreatedDateTime() {
 return createdTime.getLocalDateTime();
}
</code></pre>

I'm using Java 8 for my new project.

I'm trying to use new date and time api in java 8 however I don't know if <code>JPA 2.1</code> fully supports this new Date and Time API or not.

Please share your experience/opinion in JPA`s supports for new date and time API in Java 8.

Can I use new date and time api in Java 8 safely with JPA 2.1?

UPDATE:

I'm using Hibernate (4.3.5.Final) as JPA implementation.
