public static JsonFactory load()

Load the JSON factory with the ServiceLoader

  • An attempt is made to load a factory using the service loader META-INF/services JsonFactory.
  • Factories are sorted
  • If not factory is resolved (which is usually the default case), JacksonFactory#INSTANCE is used.

When the default Jackson codec is used and jackson-databind is available then a codec using it will be used otherwise the codec will only use jackson-core and provide best effort mapping.
