由于JButton和JTree都已經(jīng)實(shí)現(xiàn)了Serializable接口，因此Java swing組件的串行化和讀取是可以做到的。
方法就是使用ObjectInputStream讀取文件中的對(duì)象，使用ObjectOutputStream把對(duì)象寫(xiě)入文件。

如：

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import javax.swing.JButton;
import javax.swing.JTree;
public class Save {
public static void main(String[] args) {
// Write
JButton button = new JButton("TEST Button");
JTree tree = new JTree();
try {
   ObjectOutputStream outForButton = new ObjectOutputStream(
     new FileOutputStream("button"));
   outForButton.writeObject(button);
   outForButton.close();
   ObjectOutputStream outForTree = new ObjectOutputStream(
     new FileOutputStream("tree"));
   outForTree.writeObject(tree);
   outForTree.close();
} catch (FileNotFoundException e) {
   e.printStackTrace();
} catch (IOException e) {
   e.printStackTrace();
}
// Read
try {
   ObjectInputStream inForButton = new ObjectInputStream(
     new FileInputStream("button"));
   JButton buttonReaded = (JButton) inForButton.readObject();
   ObjectInputStream inForTree = new ObjectInputStream(
     new FileInputStream("tree"));
   JTree treeReaded = (JTree) inForTree.readObject();
} catch (FileNotFoundException e) {
   e.printStackTrace();
} catch (IOException e) {
   e.printStackTrace();
} catch (ClassNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
}
}
}
