仅将日期的日期部分与Hibernate中的时间戳进行比较

如果您正在寻找 按日期范围过滤 的 常规用法 （例如，从今天到明天）。我用这种方式：

YourService.java

Date fromTimestamp = new Date();Date toTimestamp = new Date();Date fromDate = DateHelper.getDateWithoutTime(fromTimestamp);Date toDate = DateHelper.getDateWithoutTime(DateHelper.getTomorrowDate(toTimestamp));

YourDAO.java

criteria.add(Restrictions.ge(TIMESTAMP_FIELD, fromDate));criteria.add(Restrictions.le(TIMESTAMP_FIELD, toDate));

DateHelper.java

public static Date getDateWithoutTime(Date date) {    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.set(Calendar.HOUR_OF_DAY, 0);    cal.set(Calendar.MINUTE, 0);    cal.set(Calendar.SECOND, 0);    cal.set(Calendar.MILLISECOND, 0);    return cal.getTime();}public static Date getTomorrowDate(Date date) {    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.add(Calendar.DATE, 1);    return cal.getTime();}

当然，每个代码中始终都有重构的空间。
