java序列化是否以某种方式改变了对象？

我将defaultTableModel对象存储在可序列化的ProductObj类中

public class ProductObj implements Serializable{

   private static final long serialVersionUID = 79839857245324985L;

   private Integer taskID;
   private List<String> data;
   private JFreeChart climateChartPanel;
   private JFreeChart productivityChartPanel;
   private JFreeChart developmentChartPanel;
   private DefaultTableModel developmentTable;
   private DefaultTableModel productivityTable;

序列化Swing组件通常被认为是个坏主意。如果需要传输或存储数据，请将数据对象与UI对象分离。奇怪的是，如果不是一个好主意，为什么DefaultTableModel实现可序列化？@chrylis他正是这么做的。他不是序列化Swing对象，而是序列化其（

Serializable

）模型。这正是你应该做的。@ USER 884025在设计时，串行化被用来在有线上传输内容，而这仍然是可能的，它不再被认为是序列化实际模型，而是内容的好主意。模型携带的附加信息可能无法序列化，例如侦听器，因此状态可能变得不稳定。将对象序列化以进行长期存储也被认为是一个坏主意，您应该看看像JAXB这样的技术instead@EJP但是

ProductObj

包含Swing组件以及

TableModel

s

private void serialize(String path) throws Exception {
    List<ProductObj> products = new ArrayList<>(controller.getFutures().size());
    for(Future<ProductObj> f : controller.getFutures())
        products.add(f.get());

    try (FileOutputStream fileOut = new FileOutputStream(Util.PathNameThisOS(path+"/"+"SimulationObjects.srz")); 
         ObjectOutputStream out = new ObjectOutputStream(fileOut)) 
    {
        //out.writeObject(products);
    }

    products = unserialize(path);
}
