🚩Issue : jakarta.validation.UnexpectedTypeException

{"timestamp":"2024-01-09T03:05:08.657+00:00","status":500,"error":"Internal Server Error","path":"/api/v1/posts"}

jakarta.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'jakarta.validation.constraints.Size' validating type 'java.lang.Integer'. Check configuration for 'deadlineMins'

Integer validator가 없다고 함

public class SpringValidatorAdapter implements SmartValidator, jakarta.validation.Validator {

이 파일 살펴봄

@Override
	public void validate(Object target, Errors errors) {
		if (this.targetValidator != null) {
			processConstraintViolations(this.targetValidator.validate(target), errors);
		}
	}

Integer가 저기서 취급하는게 아닌가봄

 

⛳Solution : Integer에 @Size 대신 @Min 혹은 @Max 사용

Size로 쓰면 안되고 Min이나 Max annotation을 써야한다고 함

@NotNull
    @Size(max=60)
    Integer deadlineMins,
    @NotNull
    @Size(max=3)
    Integer deadlineHour,

→

@NotNull
    @Max(59)
    Integer deadlineMins,
    @NotNull
    @Max(3)
    Integer deadlineHour,
