我可以使用反射api访问内部池。

private GenericObjectPool<Jedis> jedisPool() {
    try {
      Field pool = JedisConnectionFactory.class.getDeclaredField("pool");
      pool.setAccessible(true);
      Pool<Jedis> jedisPool = (Pool<Jedis>) pool.get(jedisConnectionFactory());
      Field internalPool = Pool.class.getDeclaredField("internalPool");
      internalPool.setAccessible(true);
      return (GenericObjectPool<Jedis>) internalPool.get(jedisPool);
    } catch (NoSuchFieldException | IllegalAccessException e) {
      e.printStackTrace();
    }
  }
