Spring Data ArangoDB - Migration

Migrate from Spring Data ArangoDB 3.x to 4.0

JDK 17, Spring Framework 6 and Spring Boot 3

Spring Data ArangoDB 4.0 requires:

Spring Boot Starter ArangoDB  provides integration with Spring Boot 3 .

Java Driver 7

The implementation is now based on Java Driver 7.

Exception Translation

  • exceptions in ArangoOperations.query() and repository queries (derived queries and @Query annotated methods) are now translated to Spring Data exceptions (DataAccessExceptions and subclasses)
  • OptimisticLockingFailureException is now thrown in case of _rev conflict

Serialization

  • support for data type VPackSlice has been removed in favor of Jackson type com.fasterxml.jackson.databind.JsonNode and its subclasses (ArrayNode, ObjectNode, …)

  • the underlying Java driver (accessible via com.arangodb.springframework.core.ArangoOperations#driver()) uses now the ArangoConverter bean to serialize and deserialize user data

API changes

  • CrudRepository.deleteById()now silently ignores an unknown id (as defined by API contract)
  • renamed ArangoOperations methods operating on multiple documents with All suffix (e.g. insert(Iterable) has been renamed to insertAll(Iterable)
  • ArangoOperations methods for single document manipulation have now specific return types (, DocumentDeleteEntity<T>, DocumentUpdateEntity<T>, DocumentCreateEntity<T>)
  • ArangoOperations methods for multiple documents manipulation have now specific return types as for single documents, wrapped by MultiDocumentEntity<>
  • ArangoOperations methods for documents manipulation accepting options returnNew(boolean) or returnOld(boolean) return now the deserialized entity in the response (accessible via getNew() or getOld())
  • changed the arguments order of some ArangoOperations methods for better API coherence
  • changed the arguments type of some ArangoOperations methods to be covariant
  • return updated entity from ArangoOperations.repsert()

Removed

  • removed deprecated AbstractArangoConfiguration in favor of ArangoConfiguration
  • removed support for Joda-Time
  • removed ArangoOperations.insert(String collectionName, ...) methods
  • removed previously deprecated API classes and methods

Migrate from Spring Data ArangoDB 2.x to 3.0

Annotations @Key

The annotation @Key is removed. Use @Id instead.

Annotations @Id

The annotation @Id is now saved in the database as field _key instead of _id. All operations in ArangoOperations and ArangoRepository still work with @Id and also now supports non-String fields.

If you - for some reason - need the value of _id within your application, you can use the annotation @ArangoId on a String field instead of @Id.

Note: The field annotated with @ArangoId will not be persisted in the database. It only exists for reading purposes.

ArangoRepository

ArangoRepository now requires a second generic type. This type ID represents the type of your domain object field annotated with @Id.

Examples

public class Customer {
  @Id private String id;
}

public interface CustomerRepository extends ArangoRepository<Customer, String> {

}

Annotation @Param

The annotation com.arangodb.springframework.annotation.Param is removed. Use org.springframework.data.repository.query.Param instead.

DBEntity

DBEntity is removed. Use VPackSlice in your converter instead.

DBCollectionEntity

DBCollectionEntity is removed. Use VPackSlice in your converter instead.

Migrate from Spring Data ArangoDB 1.x to 3.0

The steps are the same as for Migrating from Spring Data ArangoDB 2.x to 3.0.
