public @interface Nullable
Deprecated.
A common Spring annotation to declare that annotated elements can be
null
under certain circumstances.
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 the parameter, return value, and field level. Method
overrides should repeat parent @Nullable annotations unless they behave
differently.
Can be used in association with @NonNullApi or @NonNullFields to
override the default non-nullable semantic to nullable.
