Persisting UUID in PostgreSQL using JPA

Question

I\'m trying to persist an entity in PostgreSQL that uses UUID as primary key. I\'ve tried persisting it as a plain UUID:

@Id
@Column(name = \"customer_id\")
         


        

Answer 1

Newer version >= 8.4-701 of Postgresql JDBC driver correctly handle java.util.UUID mapping. And so do Hibernate >= 4.3.x.

See details on https://stackoverflow.com/a/780922/173149:

Map the database uuid type to java.util.UUID.
This only works for relatively new server (8.3) and JDK (1.5) versions.
