# DDD Repository pattern for [Lagom](https://www.lagomframework.com)/[Play](https://playframework.com)

API of library contains only one interface [Repository](https://www.javadoc.io/doc/org.taymyr.play/play-repository-api-java) for DDD aggregate, inspired the book 

[Implementing Domain-Driven Design](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577) by Vaughn Vernon.

## Example

### JPA

Create the interface of repository for aggregate

```java

public interface AggregateRepository extends Repository { }

```

and implement it

```java

public class AggregateRepositoryImpl extends JPARepository implements AggregateRepository {

    @Inject

    public AggregateRepositoryImpl(@Nonnull JPAApi jpaApi, @Nonnull DatabaseExecutionContext executionContext) {

        super(jpaApi, executionContext, Aggregate.class);

    }

    @Override

    public UUID nextIdentity() {

        return UUID.randomUUID();

    }

}

```
