使用的时候，只要将SwingUtils.enterPressesWhenFocused(JButton)这样就可以实现回车时候，触发按钮。

另外文本输入框回车触发事件则是：SwingUtils.enterPressesWhenFocused(JTextField textField,ActionListeneractionListener) 。其中actionListener是需要触发的事件。

importjava.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 {

    publicstatic 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);
    }

    publicstatic 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);
    }

}
