MyBatis Timestamp does conditions for queries

The first step is to convert the condition to a timestamp

        long startTime = TimeUtil.parseTimestamp(start);
        long endTime = TimeUtil.parseTimestamp(end);
 
/*对应工具类*/
   public static long parseTimestamp(String datetime){
		try{
			SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
			Date date	= dateformat.parse(datetime);
			return date.getTime()/1000;			
		}catch(Exception e){
			 e.printStackTrace();
		}
		
		return 0;
	}

Then Mapper uses .xml and in the to_timestamp

<if test="startDate !=null and startDate !='' and endDate !=null and endDate !=''">
            AND tdnm.create_time BETWEEN to_timestamp(#{startDate}) AND to_timestamp(#{endDate})
</if>
