Java手动序列化和反序列化的实现

 //序列化对象为String字符串，先对序列化后的结果进行BASE64编码，否则不能直接进行反序列化
     public static String writeObject(Object o) throws Exception {
         ByteArrayOutputStream bos = new ByteArrayOutputStream();
         ObjectOutputStream oos = new ObjectOutputStream(bos);
         oos.writeObject(o);
         oos.flush();
         oos.close();
         bos.close();
         //return new BASE64Encoder().encode(bos.toByteArray());
         return new String(bos.toByteArray(), "ISO-8859-1");
     }

     //反序列化String字符串为对象
     
     public static Object readObject(String object) throws Exception{
         //ByteArrayInputStream bis = new ByteArrayInputStream(new BASE64Decoder().decodeBuffer(object));
         ByteArrayInputStream bis = new ByteArrayInputStream(object.getBytes("ISO-8859-1"));
         ObjectInputStream ois = new ObjectInputStream(bis);
         Object o = null;
         try {
             o = ois.readObject();
         } catch(EOFException e) {
             System.err.print("read finished");
         }
         bis.close();
         ois.close();
         return o;
    }
