然後需要匯入：jedis-2.7.3.jar這個包，看如下程式碼：

package redis.main;

    //Redis的埠號
    private static int PORT = 6379;
 
    //訪問密碼
    private static String AUTH = "123456";
 
    //可用連線例項的最大數目，預設值為8；
    //如果賦值為-1，則表示不限制；如果pool已經分配了maxActive個jedis例項，則此時pool的狀態為exhausted(耗盡)。
    private static int MAX_ACTIVE = 1024;
 
    //控制一個pool最多有多少個狀態為idle(空閒的)的jedis例項，預設值也是8。
    private static int MAX_IDLE = 200;
 
    //等待可用連線的最大時間，單位毫秒，預設值為-1，表示永不超時。如果超過等待時間，則直接丟擲JedisConnectionException；
    private static int MAX_WAIT = 10000;
 
    private static int TIMEOUT = 10000;
 
    //在borrow一個jedis例項時，是否提前進行validate操作；如果為true，則得到的jedis例項均是可用的；
    private static boolean TEST_ON_BORROW = true;
 
    private static JedisPool jedisPool = null;
 
    /**

            config.setMaxTotal(MAX_ACTIVE);
            config.setMaxIdle(MAX_IDLE);
            config.setMaxWaitMillis(MAX_WAIT);
            config.setTestOnBorrow(TEST_ON_BORROW);
            jedisPool = new JedisPool(config, ADDR, PORT, TIMEOUT, AUTH);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

                return resource;
            } else {
                return null;
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
 
    /**

     */
    public static void returnResource(final Jedis jedis) {
        if (jedis != null) {
            jedisPool.close();
        }
    }
}
