I can't entirely agree with this JsonUtilCustomizer. It increases the complexity of jsonutil and allows users to re-implement jsonutil if they want to customize some parameters

It's really something we need to consider, This feature is for rest, the complexity is relative, for the end user to use JsonUtilCustomizer will make the customization easier, otherwise, because fastjson all use static parameters, customization is hard.
