Java JSON编辑器/可视化器

Question

I wrote an application that takes a JSON file as configuration. Up to this point, I wrote the JSON config by hand. However, now I want to allow other users who are not familiar with JSON format to make their own configurations. There's only 3 types of objects that the configuration needs to store, but the user should be allowed to add multiple copies of these objects. I want to write a configuration application where the user can press a button such as "Add Type A" and an object of type A is populated with default values and visualized so that the user can select properties and edit them. I know how to write an application that does this, but I feel like I'm re-inventing the wheel. Does anyone know of an open-source Java library that I can use inside my config application to handle visualization and editing a JSON file? If I'm approaching this from completely the wrong direction, please let me know.

Answer 1

I'm tempted to say "don't fear to reinvent the wheel". But the fact is that there a bunch solutions available :

How do I convert an object to JSON representation (and vice-versa)
Java representation of JSON Object
Javascript to Java using JSON

among them, GSON looks fine.

For my personal experience, Yaml turned out to be an appropriate solution.
