创建一个数组存储redis链接，失效自动创建加入数组，

附上代码一段简单代码，欢迎吐槽

package test;

import java.util.Random;

import redis.clients.jedis.Jedis;

public class RedisArrayUtil {
    private static Jedis[] jedisArray;
    private static int jedisArraySize;
    private static String jedisHost;

    private static Random random = new Random();

    private RedisArrayUtil(int jedisArraySize, String jedisHost, int jedisPort) {
        this.jedisArraySize = jedisArraySize;
        this.jedisHost = jedisHost;
        this.jedisPort = jedisPort;
        jedisPool();
    }

    @SuppressWarnings("resource")
    public static void jedisPool() {
        jedisArray = new Jedis[jedisArraySize];
        for (int i = 0; i < jedisArraySize; i++) {
            Jedis jedis = new Jedis(jedisHost, jedisPort);
            if (jedis.ping().equals("PONG")) {

            }
        }
    }

                addJedis();
