mybatis-plus 时间字段比较,默认lt/gt/ge时间比较时无效：

LambdaQueryWrapper<?> queryWrapper = Wrappers.<ConstantsRetention>query().lambda();
        
String strEnd= DateFormatUtils.format(dto.getEndTime(),"yyyy-MM-dd HH:mm:ss");
 
String start = DateFormatUtils.format(dto.getStartTime(),"yyyy-MM-dd HH:mm:ss");
 
queryWrapper.apply("UNIX_TIMESTAMP(tabulation_time) >= UNIX_TIMESTAMP('" + start + "')");
 
queryWrapper.apply("UNIX_TIMESTAMP(tabulation_time) < UNIX_TIMESTAMP('" + strEnd + "')");
