序列化，反序列化工具类

可用于redis存储（序列化对象），取出（反序列化对象）

public class SerializeUtil {

	public static byte[] serializeObj(Object obj){
		ObjectOutputStream oos = null ;
		ByteArrayOutputStream baos = null ;
		try {
			baos = new ByteArrayOutputStream();
			oos = new ObjectOutputStream(baos);
			oos.writeObject(obj);
			byte[] bytes = baos.toByteArray();
			return bytes ;
		} catch (IOException e) {
			System.out.println(8);
			return null;
		}
	}
	
	public static Object unserializeObj(byte[] bytes){
		ByteArrayInputStream bais = null;
		try {
			bais = new ByteArrayInputStream(bytes);
			ObjectInputStream ois = new ObjectInputStream(bais) ;
			return ois.readObject();
		} catch (Exception e) {
			return null ;
		}
		
	}
	
}

redis中的方法：

/**
	 * 存入对象到redis中
	 * @param key
	 * @param obj
	 * @return
	 */
	public static Boolean set(final String key,final Object obj){
		boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
			public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
				connection.set(key.getBytes(),SerializeUtil.serializeObj(obj));
				return true;
			}
		});
		return result;
	}

	/**
	 * 获取redis中的对象
	 * @param key
	 * @return
	 */
	public static String get(final String key){
		String result = redisTemplate.execute(new RedisCallback<String>() {
			public String doInRedis(RedisConnection connection) throws DataAccessException {
				byte[] result = connection.get(key.getBytes()) ;
				if (null == result || null == SerializeUtil.unserializeObj(result)) {
					return "";
				}
				return result == null ? "" : SerializeUtil.unserializeObj(result).toString();
			}
		});
		return result;
	}
