將對象緩衝到redis中

1，java配置redis用戶端

public class RedisClient implements Serializable{    private Jedis jedis;    private JedisPool jedisPool;    ShardedJedis shardedJedis;    private ShardedJedisPool shardedJedisPool;    public RedisClient(){        initialPool();        initialSharePool();        shardedJedis = shardedJedisPool.getResource();        jedis = jedisPool.getResource();    }    /**     * 初始化非切片池     */    private void initialPool(){        //池基本配置        JedisPoolConfig config = new JedisPoolConfig();        config.setMaxActive(20);        config.setMaxIdle(5);        config.setMaxWait(10001);        config.setTestOnBorrow(false);        jedisPool = new JedisPool(config, Enums.LINUX_HOST.getValue(), 6379);    }    /**     * 初始化切片池     */    private void initialSharePool(){        //池基本配置        JedisPoolConfig config = new JedisPoolConfig();        config.setMaxActive(20);        config.setMaxIdle(5);        config.setMaxWait(10001);        config.setTestOnBorrow(false);        //slave串連        List<JedisShardInfo> shardInfos = new ArrayList<JedisShardInfo>();        shardInfos.add(new JedisShardInfo(Enums.LINUX_HOST.getValue(), 6379, 1000));        //構造池        shardedJedisPool = new ShardedJedisPool(config, shardInfos);    }}

2，數組和對象的相互轉化

        1，對象實現Serializable介面，才可以序列化和還原序列化

        

        2，對象和數組相互轉化的代碼

        

public class ObjectAndByte {    public  static byte[] toByteArray (Object obj) {        byte[] bytes = null;        try {            // object to bytearray            ByteArrayOutputStream bo = new ByteArrayOutputStream();            ObjectOutputStream oo = new ObjectOutputStream(bo);            oo.writeObject(obj);            bytes = bo.toByteArray();            bo.close();            oo.close();        } catch (Exception e) {            System.out.println("translation" + e.getMessage());            e.printStackTrace();        }        return bytes;    }    /**     * 數組轉對象     * @param bytes     * @return     */    public static Object toObject (byte[] bytes) {        Object obj = null;        try {            ByteArrayInputStream bis = new ByteArrayInputStream (bytes);            ObjectInputStream ois = new ObjectInputStream (bis);            obj = ois.readObject();            ois.close();            bis.close();        } catch (IOException ex) {            ex.printStackTrace();        } catch (ClassNotFoundException ex) {            ex.printStackTrace();        }        return obj;    }}
