Introduction In this article, I’m going to show you how to map PostgreSQL ARRAY column types (e.g., text, int, double, enum, date, timestamp, UUID) to Java List entity attributes with JPA and Hibernate. As illustrated by this article, the Hypersistence Utils project provides support for mapping PostgreSQL ARRAY column types to Java Array entity attributes/ However, you can also map database ARRAY columns to java.util.List entity attributes, as it’s much more convenient to use Java Collections than Arrays.
