Joda-DateTime Date 与 String 相互转换

【参考文章】：Joda-Time 的 DateTimeFormat 问题

public class DateFormatUtils {

    /** HH 必须大写 */

    public static final String FORMAT_FULL_TIME_NO_ZONE = "yyyy-MM-dd HH:mm:ss";

    public static Date toFormatDate(String dateTimeStr) {

        DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern(FORMAT_FULL_TIME_NO_ZONE);

        DateTime dateTime = dateTimeFormatter.parseDateTime(dateTimeStr);

        return dateTime.toDate();

    }

    public static String toFormatString(Date date) {

        return new DateTime(date).toString(FORMAT_FULL_TIME_NO_ZONE);

    }

    public static String toFormatString(Date date, String pattern) {

        return new DateTime(date).toString(pattern);

    }

}
