New and Noteworthy

Spring Data Commons - 2.7

Configuration of class loader in SimpleTypeInformationMapper

SimpleTypeInformationMapper now accepts a ClassLoader to ensure class visibility from the type mapper when resolving a class name into a class. Arrangements without a configured class loader fall back to the context or system class loader which might not have access to a custom class loader (such as Spring Boot’s AppClassLoader) and that can lead to non-resolvable type hints when reading an entity on e.g. the ForkJoinPool.

Infrastructure to introspect a projection type

EntityProjection provides an API to introspect projection types in the context of an entity to determine which property paths to consider during loading.

Spring Data MongoDB - 3.4

Direct projections

The projection support through MongoTemplate and its reactive variant are refined supporting nested projections directly on the converter-level allowing to avoid superfluous and partial entity creation as interface projections are backed by a map. DTO projections are read directly into the DTO type.
