如何将一个Java对象序列化到文件里？

将对象序列化到文件

1.对象需要实现Serializable接口

public class StudentBean implements Serializable {
   ······
}

2.通过ObjectOutputStream的writeObject()方法写入和ObjectInputStream的readObject()方法来进行读取

//存进去

try {
	ObjectOutputStream os = new ObjectOutputStream(
	new FileOutputStream("D:/student.txt"));
	os.writeObject(studentList);
	os.close();
} catch (FileNotFoundException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
} catch (IOException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
}

//读出来

try {
	ObjectInputStream is = new ObjectInputStream(
	new FileInputStream("D:/student.txt"));
	ArrayList<StudentBean> list = new ArrayList<StudentBean>();
	list = (ArrayList<StudentBean>) is.readObject();
	for (int i = 0; i < list.size(); i++) {
		System.out.println(list.get(i).toString());
	}
} catch (FileNotFoundException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
} catch (IOException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
} catch (ClassNotFoundException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
}
