1.首先引入jar包

<dependency>
                    <groupId>cn.hutool</groupId>
                    <artifactId>hutool-all</artifactId>
                    <version>5.3.7</version>
    </dependency>

2.计算差值

public static DateFormat getDateTimeFormat(){
        
    		DateFormat dtf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    		return dtf;
    	}
    //获取两个时间之前的差值(小时)
    	public static String getSjScz(String rq1,String rq2)throws Exception{
        
    		DateFormat simpleFormat = getDateTimeFormat();
    		Date timeDate1 = simpleFormat.parse(rq1);
    		Date timeDate2 = simpleFormat.parse(rq2);
    		long hour=DateUtil.between(timeDate1, timeDate2, DateUnit.HOUR);
    		return String.valueOf(hour);
    
    	}
    	//获取两个时间之前的差值(小时带小数)
    	public static String getSjSch(String rq1,String rq2)throws Exception{
        
    		DateFormat simpleFormat = getDateTimeFormat();
    		Date timeDate1 = simpleFormat.parse(rq1);
    		Date timeDate2 = simpleFormat.parse(rq2);
    		long time1 = timeDate1.getTime();
    		long time2 = timeDate2.getTime();
    		double minutes = ((time1 - time2)*1.0 / (1000 * 60*60));
    		return String.valueOf(minutes);
    	}
    	//获取两个时间之前的差值(分钟)
    	public static String getSjScm(String rq1,String rq2)throws Exception{
        
    		DateFormat simpleFormat = getDateTimeFormat();
    		Date timeDate1 = simpleFormat.parse(rq1);
    		Date timeDate2 = simpleFormat.parse(rq2);
    		long minutes=DateUtil.between(timeDate1, timeDate2, DateUnit.MINUTE);
    		return String.valueOf(minutes);
    
    	}
