위에 코드를 실행시키니 아래의 에러가 나옴

spring.mvc.date-format=yyyy-MM-dd

위에 프로퍼티를 추가해서 사용가능하게 처리 할려고 함

하지만 안됨

내가 사용하고 있는 버전은 2.0.1 버전으로 코드를 확인 해봄

org.springframework.boot.autoconfigure.web.format.WebConversionService 클래스에

private void registerJsr310() {
	DateTimeFormatterRegistrar dateTime = new DateTimeFormatterRegistrar();
	if (this.dateFormat != null) {
		dateTime.setDateFormatter(DateTimeFormatter.ofPattern(this.dateFormat)
				.withResolverStyle(ResolverStyle.STRICT));
	}
	dateTime.registerFormatters(this);
}

위에 메소드를 보면 ResolverStyle.STRICT로 되어 있다.

				.withResolverStyle(ResolverStyle.SMART));
	}
	dateTime.registerFormatters(this);
}

v2.0.5.RELEASE 에 ResolverStyle.SMART 로 변경 되었다

이렇게 되서 위에 spring.mvc.date-format=yyyy-MM-dd 추가 만으로도 잘 동작하게 됨
