在IntelliJ 13上运行Google AppEngine应用程序

我在命令行中使用了guestbook appengine应用程序.为了加快开发速度,我需要在IntelliJ IDEA IDE中工作.但是,我无法运行该应用程序.我想问题是配置.我该如何配置IDE？

当我打开pom项目并尝试运行它时,IntelliJ显示Warning: App Engine facet not found in 'guestbook-war:war exploded' artifact.配置完所有其他选项后,我可以运行该应用程序.但是,IDEA然后显示:

Java时间格式化

我有方法

public static void testDateFormat() throws ParseException {
    DateFormat dateFormat=new SimpleDateFormat("HH:mm:ss");
    Date hora;
    hora=dateFormat.parse("00:00:01");
    System.out.println(hora.getHours()+" "+hora.getMinutes());
    System.out.println("Date "+hora);
    System.out.println("Seconds "+TimeUnit.MILLISECONDS.toSeconds(hora.getTime()));
}
