我有下面的代码，它将一个列表存储到文件，然后存储到mysql blob列。是否可以从数据库中恢复该列表？

ArrayList<String> myList = new ArrayList<String>();
File tempFile = File.createTempFile("myFile.temp");
tempFile.deleteOnExit();
FileOutputStream fileOutputStream = new FileOutputStream(tempFile);
ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);
objectOutputStream.writeUnshared(myList);
objectOutputStream.close();
String trailQuery = "INSERT INTO table (tempFile) VALUES (?)";
PreparedStatement preparedStatement = connection.prepareStatement(trailQuery);
preparedStatement.setObject(1, tempFile);

我试着读这个，但我得到一个filenotfoundexception

if (resultSet.next()) {
    InputStream fileInputStream = resultSet.getBinaryStream("tempFile");
    ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
    File inner = (File) objectInputStream.readObject();
    FileInputStream fileInputStreamInner = new FileInputStream(inner);
    ObjectInputStream objectInputStreamInner = new ObjectInputStream(fileInputStreamInner);
    ArrayList<String> myList = (ArrayList<String>) objectInputStreamInner.readObject();
    System.out.println(myList.size());
}

例外

java.io.FileNotFoundException: \tmp\myFile.1708309680603860570.temp (The system cannot find the path specified)
