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(); }
