是否可以在没有任何第三方库的情况下使用@RequestBody将JSON转换为Java bean

Question

I have a AJAX request with data in json format like:

["name":"Some Name",
  "address":{"id":1, "street":"some street"}]

and Java Bean would be look like:

class Person {
  private String name;
  private Address address;

  //getters and setters
}

class Address {
  private int id;
  private String street;

  //getters and setters
}

is it possible to use @RequestBody in handler method to get Person without using any third party libraries like: Gson, Jackson etc. if yes how?

Answer 1

No, neither Java nor Spring comes with a JSON mapper. You could write your own, and it wouldn't be a third-party library anymore. But I don't think that's a good idea. What's wrong with Jackson?

Answer 2

Well,

spring WILL use third party library - I mean it has to be on classpath, but you dont have to write any mapping code by yourself for simple cases as you have shown. Just be sure to really add setters and default constructors to both entities and it should work.
