Java swing组件的串行化和读取

由于JButton和JTree都已经实现了Serializable接口,因此Java swing组件的串行化和读取是可以做到的。
方法就是使用ObjectInputStream读取文件中的对象,使用ObjectOutputStream把对象写入文件。

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();
}

}

}
