WebBindingInitializer 활용

날짜 또는 숫자의 컴마 공통처리

 

1. 커스텀 클래스 생성

        }
    }

2. 컨버트 클래스 샘플

import java.beans.PropertyEditorSupport;
import org.apache.commons.lang3.StringUtils;

public class ConvertNumber extends PropertyEditorSupport {
	@Override
	public void setAsText(String text) throws IllegalArgumentException {
		if (StringUtils.isEmpty(text)) {
			setValue(null);
			return;
		}
		setValue(text.replaceAll("\\D", ""));
	}
}
