RequestBodyAdvice

interface RequestBodyAdvice

Allows customizing the request before its body is read and converted into an Object and also allows for processing of the resulting Object before it is passed into a controller method as an @RequestBody or an HttpEntity method argument.

Implementations of this contract may be registered directly with the RequestMappingHandlerAdapter or more likely annotated with @ControllerAdvice in which case they are auto-detected.
