Free online Java POJO starter that infers fields from JSON for REST clients and server models.
How it works
This tool infers fields and types from JSON and generates Java classes. It helps bootstrap DTOs from API responses.
Example
Input:
{"id":1,"name":"Ana"}
Output:
class Root { private int id; private String name; }FAQ
Will it add Jackson annotations?
Some generators can. If not, ensure field names match your JSON mapper configuration.
How are null values handled?
Nulls may map to boxed types or nullable references depending on generator settings.
