package com.inforstack.qpdw.converter;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.core.convert.converter.Converter;
import org.springframework.util.StringUtils;
public class StringToDateConverter implements Converter<String, Date> {
	private static final String dateFormat = "yyyy-MM-dd HH:mm:ss";
	private static final String shortDateFormat = "yyyy-MM-dd";
	@Override
	public Date convert(String value) {
		if (StringUtils.isEmpty(value))
			return null;
		value = value.trim();
		try {
			if (value.contains("-")) {
				SimpleDateFormat formatter;
				if (value.contains(":"))
					formatter = new SimpleDateFormat(dateFormat);
				else
					formatter = new SimpleDateFormat(shortDateFormat);
				Date dtDate = formatter.parse(value);
				return dtDate;
			} else if (value.matches("^\d+$")) {
				Long lTime = new Long(value);
				return new Date(lTime);
			}
		} catch (Exception e) {
			throw new RuntimeException(String.format("parser %s to Date fail", value));
		}
		throw new RuntimeException(String.format("parser %s to Date fail", value));
