Class JacksonHelper

  • All Implemented Interfaces:
    
public class JacksonHelper

                    
    XML limitation
The common uses are:
(1) single element node, XML can not distinguish between a single value or only one value in the array, unless nested wrap.
(2) Xml can not recognize the data type, while Json has string, number, boolean, object, array
