//常用于点赞,阅读数等统计,

Long increment = redisTemplate.opsForValue().increment(key4, 1L);//注意为long类型

//给指定的key的value的值做增减,并返回增减后的值

Long increment2 = redisTemplate.opsForValue().increment(key4, -1L);

//给指定的key的value的值做增减,

redisTemplate.opsForValue().append(key3, "和王六");//在key键对应值的右面追加值value

String s1 = opsForValue.get(key3);

//可以看到并没有删除等方法,博主研究了一下可以这样:21.del key------21.

redisTemplate.delete(key3);//可以批量删

redisTemplate.delete(strings);//可以批量删
