@PostMapping("/register")
    public ResponseEntity<?> Register(@RequestBody @Valid CreateUserDto createUserDto, BindingResult bindingResult) {
        if (bindingResult.hasErrors())
            return ResponseEntity
                    .badRequest()
                    .body(new MessageResponse(bindingResult.getAllErrors().toString()));
        return authService.createUserFromRegister(createUserDto);
    }

You are mixing Jakarta EE and Java EE

#

if you are using Spring Boot 3, use jakarta.validation imports

#

and remove all javax stuff from your dependencies

unique walrus Jun 17, 2024, 9:01 PM

#

so javax library is not worked?

summer anvil Jun 17, 2024, 9:15 PM

#

In a Jakarta EE project, javax things don't work

#

don't mix them

#

Jakarta EE replaced Java EE
