本文详细解析了Java中对象序列化的过程，包括如何实现对象的序列化与反序列化，以及序列化前后对象状态的变化。通过实例演示了如何在序列化过程中模拟加密与解密操作，并在反序列化时进行相应的处理。

private static final long serialVersionUID = 1L;

	private String password = "pass";

	public String getPassword() {

	private void writeObject(ObjectOutputStream out) {
		try {
			PutField putFields = out.putFields();
			System.out.println("原密码:" + password);
			password = "encryption";//模拟加密
			putFields.put("password", password);
			System.out.println("加密后的密码" + password);

		try {
			GetField readFields = in.readFields();
			Object object = readFields.get("password", "");
			System.out.println("要解密的字符串:" + object.toString());
			password = "pass";//模拟解密,需要获得本地的密钥
		} catch (IOException e) {
