rest - Spring Request Mapping post vs put, same method, same logic, but -

i have 2 method: first 1 create product:

@requestmapping(method = requestmethod.post)     public responseentity<?> create(@validated productdto productdto){         productservice.addproduct(productdto);         return new responseentity<>("maxsulot ro'yhatga qo'shildi", httpstatus.ok);     } 

another 1 update product:

@requestmapping(method = requestmethod.put)     public responseentity<?> update(@validated productdto productdto){         productservice.update(productdto);         return new responseentity<>("maxsulot ma'lumotlari yangilandi", httpstatus.ok);     } 

now, surprized that, if sent same data post method works fine(screen1), put(screen2) method return validation error. screen1(post)

screen2(put)

what problem is? mydto class:

public class productdto {      private long id;      private multipartfile file;      @notnull     @size(min = 2, max = 50)     private string productname;      @notnull     private long productprice;      private string productinfo;      @notnull     private long categoryid;      private string unitofmeasurement;      // getters , setters } 

i can see have @validated should validate request body according jsr-303.

seems not consistent when post , put. validates/not validating , return error because body not match validation rules placed on productdto.

in docs saw should @valid @requestbody instead of putting @validated.

try change above , see if work more consistently.
