Can the Map object of a wrapper DTO be converted with POST : @ModelAttribute?

edit

No, the Map object of a wrapper DTO cannot be converted with POST: @ModelAttribute.

The @ModelAttribute annotation is used to bind the incoming HTTP request to a Java object. However, @ModelAttribute only supports binding of simple Java bean properties and cannot directly bind wrapper classes like Map.

To bind the Map object of a wrapper DTO, one can use @RequestBody annotation and pass the JSON data in the request body as a string. In the controller, the JSON data can be deserialized into the Map object using a JSON parsing library like Jackson or Gson.
