java对象序列化和反序列化,redis存入和获取对象

最近使用redis发现直接存储序列化后的对象更方便,现提供java序列化和反序列化的代码

1.序列化代码:

    public static byte[] serialize(Object object) {
        ObjectOutputStream oos = null;
        ByteArrayOutputStream baos = null;
        try {
            //序列化
            baos = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(baos);
            oos.writeObject(object);
            byte[] bytes = baos.toByteArray();
            return bytes;
        } catch (Exception e) {
            
        }
        return null;
    }

2.反序列化代码:

public static Object unserialize(byte[] bytes) {
    ByteArrayInputStream bais = null;
    try {
        //反序列化
        bais = new ByteArrayInputStream(bytes);
        ObjectInputStream ois = new ObjectInputStream(bais);
        return ois.readObject();
    } catch (Exception e) {
     
    }
        return null;
    }

3.向redis中存入序列化后的对象

public static void setObject(Jedis jedis,int index,String key,Object obj) throws Exception {
        redisFactory.setBytes(jedis,index,key.getBytes(), SerializeUtil.serialize(obj));
        
    }

4.从redis获取对象

    public static Object getObject(Jedis jedis,int index,String key) throws Exception {
        byte[] objSer = redisFactory.getBytes(jedis,index,key.getBytes());
        return SerializeUtil.unserialize(objSer);
    }
