通过Java日期时间API系列9-----Jdk8中java.time包中的新的日期时间API类的Period和Duration的区别 ,可以看出java8设计非常好,新增了Period和Duration类,专用于对比2个时间场景:
Period,可以获取2个时间相差的年月日的属性。
Duration,可以获取2个时间相差总的天时分秒毫秒纳秒。
下面应用:
/** * 获取2个日期的相差年月天的年数部分 * @param startInclusive * @param endExclusive * @return */ public static long betweenYears(LocalDateTime startInclusive, LocalDateTime endExclusive){ Objects.requireNonNull(startInclusive, "startInclusive"); Objects.requireNonNull(endExclusive, "endExclusive"); return Period.between(DateTimeConverterUtil.toLocalDate(startInclusive), DateTimeConverterUtil.toLocalDate(endExclusive)).getYears(); } /** * 获取2个日期的相差年月天的年数部分 * @param startInclusive * @param endExclusive * @return */ public static long betweenYears(Date startInclusive, Date endExclusive){ Objects.requireNonNull(startInclusive, "startInclusive");

} /** * 获取2个日期的相差年月天的月数部分 * @param startInclusive * @param endExclusive * @return */ public static long betweenMonths(LocalDateTime startInclusive, LocalDateTime endExclusive){ Objects.requireNonNull(startInclusive, "startInclusive");
