  • RedisPoolUtils 工具类

    JedisPool使用的时候版本不同写法是不一样的,因为官方废弃升级了一些API,可以做替换:

    废弃写法:
    public String get(String key) {
            Jedis jedis = null;
            String value = null;
            try {
                jedis = pool.getResource();
                value = jedis.get(key);
            } catch (Exception e) {
                pool.returnBrokenResource(jedis);
                e.printStackTrace();
            } finally {
                returnResource(pool, jedis);
            }
                return value;
        }
    可替换 :
    
    ...
    finally {
      if (jedis != null) {
        jedis.close();
      }

    未替换的全部方法工具类:
