主要实现方法:
//将List转化为String
public static String SceneList2String(List SceneList)
throws IOException {
// 实例化一个ByteArrayOutputStream对象,用来装载压缩后的字节文件。
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
// 然后将得到的字符数据装载到ObjectOutputStream
ObjectOutputStream objectOutputStream = new ObjectOutputStream(
byteArrayOutputStream);
// writeObject 方法负责写入特定类的对象的状态,以便相应的 readObject 方法可以还原它
objectOutputStream.writeObject(SceneList);
// 最后,用Base64.encode将字节文件转换成Base64编码保存在String中
String SceneListString = new String(Base64.encode(
byteArrayOutputStream.toByteArray(), Base64.DEFAULT));
// 关闭objectOutputStream
objectOutputStream.close();
return SceneListString;
}
//将String转化成List
@SuppressWarnings("unchecked")
public static List String2SceneList(String SceneListString)
throws StreamCorruptedException, IOException,
ClassNotFoundException {
byte[] mobileBytes = Base64.decode(SceneListString.getBytes(),
Base64.DEFAULT);
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(
mobileBytes);
ObjectInputStream objectInputStream = new ObjectInputStream(
byteArrayInputStream);
List SceneList = (List) objectInputStream
.readObject();
objectInputStream.close();
return SceneList;
}
