# Hibernate Base Entity

A base class for Hibernate-managed JPA entities with proper 

implementations of `equals()` and `hashCode()`. Inspired by 

[Andrey Oganesyan](https://github.com/andreyoganesyan)'s, 

[Georgii Vlasov](https://github.com/honest-niceman)'s, 

[Thorben Janssen](https://github.com/thjanssen)'s posts 

([1](https://habr.com/ru/companies/haulmont/articles/564682/),

on side effects that Lombok's 

`@EqualsAndHashCode` annotation brings in when applied to such 

entities:

- HashSet and HashMap incorrectly work with the entities,

- Hibernate may load data for lazy fields where not intended.

The new superclass solves both of these problems.

# How to use

1. Copy the class to your project.

2. Inherit JPA entities from the class.

3. Ensure that the primary key in related tables has name `id` and 

type `UUID`.
