## 注釈型 DynamoDBVersionAttribute

-     @Retention(value=RUNTIME)
      @Target(value=METHOD)
      public @interface DynamoDBVersionAttribute

  Annotation for marking a property as an optimistic locking version attribute. Applied to the getter method for the class's version property.

  Only nullable, integral numeric types (e.g. Integer, Long) can be used as version properties. On a save() operation, the `DynamoDBMapper` will attempt to increment the version property and assert that the service's value matches the client's. New objects will be assigned a version of 1 when saved.
