Net.sf.json.JSON convert JSON-only array to list

Net.sf.json processing a pure JSON array to convert to a list type

For example: {"UserIDs": [1000000,1000001]}, convert it to an array of integers

Summary:

If the front-end incoming JSON object is accepted in development, it is recommended that the object be passed in, and the result will be sent out to the object, everything is Object!

Private list<integer> userids; it is more convenient to accept directly with an object.
