      • setTypePrecedence

        public void setTypePrecedence​(Jackson2JavaTypeMapper.TypePrecedence typePrecedence)
        Description copied from interface: Jackson2JavaTypeMapper
        Set the precedence for evaluating type information in message properties. When using @KafkaListener at the method level, the framework attempts to determine the target type for payload conversion from the method signature. If so, this type is provided by the MessagingMessageListenerAdapter.

        By default, if the type is concrete (not abstract, not an interface), this will be used ahead of type information provided in the __TypeId__ and associated headers provided by the sender.

        If you wish to force the use of the __TypeId__ and associated headers (such as when the actual type is a subclass of the method argument type), set the precedence to Jackson2JavaTypeMapper.TypePrecedence.TYPE_ID.

        Specified by:
        setTypePrecedence in interface Jackson2JavaTypeMapper
        typePrecedence - the precedence.
