Spring Data Build - 2.7
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.
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.
