Bean Validation 2.0 - you’ve put your annotations everywhere!
summary
Bean Validation 2.0 makes Java 8 a hard requirement and adds concrete features: @Repeatable constraints for multiple validation groups, container element validation (type-use annotations) to validate list elements, map keys and values and cascade into nested collections, and Optional support plus full Java Time API constraints including new futureOrPresent/pastOrPresent rules. It defines new constraints (NotEmpty/NotBlank/Positive/etc.), a value extractor SPI for Guava or other collections, ships a faster Hibernate Validator reference implementation, and is available for WildFly (patch) and Spring 5.
