A common Spring annotation to declare that parameters and return values are to be considered as non-nullable by default for a given package.Leverages JSR-305 meta-annotations to indicate nullability in Java to common tools with JSR-305 support and used by Kotlin to infer nullability of Spring API.
Should be used at package level in association with

annotations at parameter and return value level.- 从以下版本开始:
