MongoDB中的日期：将Date对象插入Mongo数据库时，日期比其早1天

final String dateString = "Jan 2, 2012";final DateTimeFormatter dtf = new DateTimeFormatterBuilder().appendMonthOfYearShortText().appendLiteral(" ").appendDayOfMonth(1).appendLiteral(", ").appendYear(4, 4).toFormatter();final DateTime jodaDate = dtf.parseDateTime(dateString);System.out.println(jodaDate);final Date javaDate = new Date(jodaDate.getMillis());System.out.println(javaDate);

输出为

2012-01-02T00:00:00.000+02:00Mon Jan 02 00:00:00 EET 2012

下一步：

final String dateString = "Jan 1, 2012";

输出为：

2012-01-01T00:00:00.000+02:00Sun Jan 01 00:00:00 EET 2012
