public @interface CommandHandling

Annotation to be used in favor of defining CommandHandlerDefinition Beans.

It can be placed on public methods returning void or any other CommandHandler result. Such methods may have any of the following unique parameter types, in any order:

• a mandatory type derived from Command representing the CommandHandlerDefinition.commandClass()
• an optional meta-data Map
• a type derived from Object representing the CommandHandlerDefinition.instanceClass()
• a CommandEventPublisher with the generic type matching the CommandHandlerDefinition.instanceClass()
• any number of Autowired annotated parameters, resolving to single beans within the ApplicationContext

To be able to derive the CommandHandlerDefinition.instanceClass(), any of the latter two parameters is optional, but not both.

The method must be contained within an AnnotatedBeanDefinition, for instance within Components or Configurations.
