Repositories

Spring Data Commons provides a composable repository infrastructure which Spring Data ArangoDB is built on. These allow for interface-based composition of repositories consisting of provided default implementations for certain interfaces (like CrudRepository) and custom implementations for other methods.

The base interface of Spring Data ArangoDB is ArangoRepository. It extends the Spring Data interfaces PagingAndSortingRepository and QueryByExampleExecutor. To get access to all Sping Data ArangoDB repository functionallity simply create your own interface extending ArangoRepository<T, ID>.

The type T represents your domain class and type ID the type of your field annotated with @Id in your domain class. This field is persistend in ArangoDB as document field _key.

Examples

@Document
public class MyDomainClass {
  @Id
  private String id;

}

public interface MyRepository extends ArangoRepository<MyDomainClass, String> {

}

Instances of a Repository are created in Spring beans through the auto-wired mechanism of Spring.

public class MySpringBean {

  @Autowired
  private MyRepository rep;

}
