插件开发

下了个社区版，先试试 Hello World ，后续尝试更多花样

public class HelloAction extends AnAction {

    @Override
    public void actionPerformed(AnActionEvent e) {
        Date date = new Date();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String formatDate = sdf.format(date);
        Messages.showMessageDialog(String.format("It is %s now",formatDate), "Good Morning", Messages.getWarningIcon());
    }
}

心情的起伏

人生总是很难一帆风顺，总会磕磕绊绊，所以是否能够不受影响，坚定地去做自己想做的事就显得尤为重要！

插入时间插件

每次写完博客，手动写更新时间真的挺烦，自己动手，丰衣足食
