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:

• JDK 17 
• Spring Framework 6 

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.
