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：
