JsonSerializer.handledType介绍

[英]Method for accessing type of Objects this serializer can handle. Note that this information is not guaranteed to be exact -- it may be a more generic (super-type) -- but it should not be incorrect (return a non-related type).

Default implementation will return null, which essentially means same as returning Object.class would; that is, that nothing is known about handled type.
