1.获取某段时间内的时间间隔,小时为单位,分钟为单位

/**     * 获取时间间隔,小时为单位     *      * @param startTime     * @param endTime     * @return     */    private long getHourTimeSpace(String startTime, String endTime) {        SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");        Date beginDate = null;        ;        Date endDate = null;        try {            beginDate = format.parse(startTime);            endDate = format.parse(endTime);        } catch (ParseException e) {            logger.error("时间解析失败", e);        }        long space = (endDate.getTime() - beginDate.getTime()) / (60 * 60 * 1000);        return space;    }    /**     * 获取时间间隔,分钟为单位     *      * @param startTime     * @param endTime     * @return     */    private long getMinuteTimeSpace(String startTime, String endTime) {        SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");        Date beginDate = null;        ;        Date endDate = null;        try {            beginDate = format.parse(startTime);            endDate = format.parse(endTime);        } catch (ParseException e) {            logger.error("时间解析失败", e);        }        long space = (endDate.getTime() - beginDate.getTime()) / (60 * 1000);        return space;    }

2.获取下一阶段的时间(下一小时,下一分钟)

/**     * 根据时间增量获取下一阶段时间(小时)     *      * @param paramTime     * @param increment     * @return     */    private String getNextHourTime(String paramTime, int increment) {        SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss");        Date date = null;        try {            date = (Date) formatter.parse(paramTime);        } catch (ParseException e) {            logger.error("时间格式化出错", e);            return paramTime;        }        Calendar cal = Calendar.getInstance();        cal.setTime(date);        cal.add(Calendar.HOUR_OF_DAY, increment);        Timestamp ts = new Timestamp(cal.getTimeInMillis());        date = ts;        return formatter.format(date);    }    /**     * 获取下一分钟时间     * @param paramTime     * @param increment     * @return     */    private String getNextMinuteTime(String paramTime, int increment) {        SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss");        Date date = null;        try {            date = (Date) formatter.parse(paramTime);        } catch (ParseException e) {            logger.error("时间格式化出错", e);            return paramTime;        }        Calendar cal = Calendar.getInstance();        cal.setTime(date);        cal.add(Calendar.MINUTE, increment);        Timestamp ts = new Timestamp(cal.getTimeInMillis());        date = ts;        return formatter.format(date);    }
