关于java:redisTemplate批量操作

1.redisTemplate的incr自增

    public Integer incr(String key, Date expireDate) {        key = getKey(key);        RedisAtomicLong entityIdCounter = new RedisAtomicLong(key, redisTemplate.getConnectionFactory());        entityIdCounter.expireAt(expireDate);        Long increment = entityIdCounter.incrementAndGet();        return increment.intValue();    }

2.查问蕴含某字符的key列表scan操作

    public Set<String> scan(String matchKey) {        Set<String> keys = (Set<String>) redisTemplate.execute((RedisCallback<Set<String>>) connection -> {            Set<String> keysTmp = new HashSet<>();            Cursor<byte[]> cursor = connection.scan(new ScanOptions.ScanOptionsBuilder().match(matchKey + "*").count(1000).build());            while (cursor.hasNext()) {                keysTmp.add(new String(cursor.next()));            }            return keysTmp;        });        return keys;    }

3.批量查问key对应的值列表

//批量查问缓存列表，返回值按顺序排列，在某个key不存在时，对应地位返回null    public List<Integer> getMutiIncr(Collection<String> list) {        if (CollectionUtils.isEmpty(list)){            return new ArrayList<>();        }        ValueOperations ops = redisTemplate.opsForValue();        return ops.multiGet(list);    }

4.批量删除key列表对应的缓存

    public void deleteBachKeysWithEnv(Collection<String> keys) {        if (!CollectionUtils.isEmpty(keys)) {            redisTemplate.delete(keys);        }    }

5.key的指定

hash构造通常存储map类型的数据，不适宜存有incr需要的数据key1:key2:key3构造的数据，不便读取
