Support `@Validated` on method parameter

[hatotsumuri]

Hi.
I'm trying to add validation with GraphQL.

But "@validated" not working with "GraphQlController".
(I tried "GraphQlController × @Valid" and "RestController × @Validated" and they worked.)

Below is the source code.
If there are any missing settings, please kindly advise.

Thanks.

■Query

query ($accountCondition: AccountCondition)  {
	findAccountByCondition(accountCondition: $accountCondition) {
		accountId
		accountName
	}
}

■Query variables

{
	"accountCondition": {
		"accountName": "test"
	}
}

■schema.graphqls

input AccountCondition {
    accountId: Int
    accountName: String
}

type Account {
    accountId: ID!
    accountName: String
 }

type Query {
    findAccountByCondition(accountCondition: AccountCondition): [Account]
}

■AccountCondition

@Data
public class AccountCondition {
	@NotNull
	private Long accountId;
	private String accountName;
}

■GraphQLController × @validated → Validation not works.

import org.springframework.validation.annotation.Validated;
…
@Controller
@RequiredArgsConstructor
public class GraphQlController {
	private final AccountService accountService;

	@QueryMapping
	public List<Account> findAccountByCondition(
			@Argument @Validated AccountCondition accountCondition) {
		List<Account> accountList = accountService.findByCondition(
				accountCondition);
		return accountList;
	}
}

■GraphQLController × @Valid→ Validation works.

import javax.validation.Valid;
…
@Controller
@RequiredArgsConstructor
public class GraphQlController {
	private final AccountService accountService;

	@QueryMapping
	public List<Account> findAccountByCondition(
			@Argument @Valid AccountCondition accountCondition) {
		List<Account> accountList = accountService.findByCondition(
				accountCondition);
		return accountList;
	}
}

■RestController × @validated → Validation works.

import org.springframework.validation.annotation.Validated;
…
@Controller
@RequiredArgsConstructor
public class RestController {
	private final AccountService accountService;

	@PostMapping("/account/search")
	@ResponseBody
	public Result findAccountByCondition(
			@RequestBody @Validated AccountCondition accountCondition) {
		List<Account> accountList = accountService.findByCondition(
				accountCondition);
		return ResultUtil.newSuccess(accountList);
	}
}

We call standard bean validation to validate all the method parameters, and it does look like that requires @Valid.

Are you trying to specify validation groups? We do check for @Validated on the method, so you can specify groups that way still, but otherwise as it is currently you do need @Valid to trigger cascaded validation.

I think we could enhance our validation support to detect method parameters with @Validated but without @Valid and to apply validation on them, in addition to invoking standard bean validation for other method parameters.

Thank you for your advice.

Are you trying to specify validation groups?

Yes, I would like to use validation groups in graphGL.

We do check for @validated on the method, so you can specify groups that way still.

Thank you for the useful information.
I will try this implementation.

It would be great if your can support this.

Thanks.
