    Method called to create a "default instance" of the bean, currently only needed for obtaining default field values which may be used for suppressing serialization of fields that have "not changed".
    
    参数:
    fixAccess - If true, method is allowed to fix access to the default constructor (to be able to call non-public constructor); if false, has to use constructor as is.
    
    返回:
    Instance of class represented by this descriptor, if suitable default constructor was found; null otherwise.

    Method for getting ordered list of named Creator properties. Returns an empty list is none found. If multiple Creator methods are defined, order between properties from different methods is undefined; however, properties for each such Creator are ordered properly relative to each other. For the usual case of just a single Creator, named properties are thus properly ordered.
  - findSerializationInclusion

```
    Method for determining whether null properties should be written out for a Bean of introspected type. This is based on global feature (lowest priority, passed as argument) and per-class annotation (highest priority).
