我创建了一些小的方法作为Util类,例如以下代码:
public class Util { public static final String DATETIME_PATTERN="YYYY/MM/DD - HH:mm:ss"; public static String getDateTime() { SimpleDateFormat sdf=new SimpleDateFormat(DATETIME_PATTERN); return sdf.format(getToday()); } public static Date getToday() { //Calendar today=Calendar.getInstance(); //didn't help Calendar today=Calendar.getInstance(Locale.TAIWAN); //didn't fix //Calendar today=Calendar.getInstance(TimeZone.getTimeZone("GMT+08:00")); //didn't fix as well return today.getTime(); } }
并且,进行了非常简单的运行,如下所示:
//run in main class System.out.println("Generating sitemap.xml, please wait..."+Util.getDateTime());
结果是一个很奇怪的日期-> 2017/07/187
//Console result: Generating sitemap.xml, please wait...2017/07/187 - 15:27:21
搜索了类似的问题,并尝试了TimeZone,Locale,但没有帮助。有什么建议 ?
顺便说一句,这是我的环境:
您格式化日期的方式有问题。尝试将其更改为此
public static final String DATETIME_PATTERN="yyyy/MM/dd - HH:mm:ss";
