Introduced annotations CreatedBy, CreatedDate, LastModifiedBy and LastModifiedDate to allow demarcating fields as auditing related ones. The date related annotations require a field type of either DateTime, Date, Long or a primitive long. All these annotations can be used as meta-annotations.
Extracted an AuditingHandler from Spring Data JPA which allows to transparently set auditing information on objects implementing Auditable or use the newly introduced annotations in a store independent manner. This allows other stores to implement adapters to provide auditing support as well.
Introduced a more convenient way of finding fields in ReflectionUtils using the FieldFilters of core Spring. The API allows to select fields based on a filter and can transparently check that only one field matches the given filter if desired.
