使用的時候，只要將SwingUtils .enterPressesWhenFocused(JButton)這樣就可以實現回車時候，觸發按鈕。

另外文本輸入框回車觸發事件則是：SwingUtils .enterPressesWhenFocused(JTextField textField,ActionListener actionListener) 。其中actionListener是需要觸發的事件。

import java.awt.event.ActionListener;

import java.awt.event.KeyEvent;

import javax.swing.JButton;

import javax.swing.JComponent;

import javax.swing.JTextField;

import javax.swing.KeyStroke;

public class SwingUtils {

public static void enterPressesWhenFocused(JButton button) {

button.registerKeyboardAction(button.getActionForKeyStroke(KeyStroke

.getKeyStroke(KeyEvent.VK_SPACE, 0, false)),

KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0, false),

JComponent.WHEN_FOCUSED);

button.registerKeyboardAction(button.getActionForKeyStroke(KeyStroke

.getKeyStroke(KeyEvent.VK_SPACE, 0, true)),

KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0, true),

JComponent.WHEN_FOCUSED);

}

public static void enterPressesWhenFocused(JTextField textField,

ActionListener actionListener) {

textField.registerKeyboardAction(actionListener,

KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0, false),

JComponent.WHEN_FOCUSED);

textField.registerKeyboardAction(actionListener,

KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0, true),

JComponent.WHEN_FOCUSED);

}

}
