Class UtilJackson

java.lang.Object

org.thales.punch.libraries.utils.api.UtilJackson

public class UtilJackson
extends Object

Use this jackson serializer to get pojos from json strings and vice versa. Say you have a pojo like this :

 public class Pool {
        public int age;
        public Pool() {}
 }
 

Here is how you transform it into json back and forth.

 // Get a pojo from a string
 String json = "{\"age\":2}";
 Pool pojo = PojoJsonSerializer.serializer().fromJson(json, Pool.class);
 
 String back = PojoJsonSerializer.serializer().toString(pojo);
