以字符串形式获取DateTime dayOfWeek/dayOfMonth

Question

如何将星期几或月几作为字符串获取？而不需要做像这样的事情：

        DateTime now = DateTime.now();
        String dayOfWeek = null;
        switch(now.getDayOfWeek()) {
            case DateTimeConstants.MONDAY:
                dayOfWeek = "Monday";
                break;
            case DateTimeConstants.TUESDAY:
                dayOfWeek = "Tuesday";
                break;
            case DateTimeConstants.WEDNESDAY:
                dayOfWeek = "Wednesday";
                break;
            case DateTimeConstants.THURSDAY:
                dayOfWeek = "Thursday";
                break;
            case DateTimeConstants.FRIDAY:
                dayOfWeek = "Friday";
                break;
            case DateTimeConstants.SATURDAY:
                dayOfWeek = "Saturday";
                break;
            case DateTimeConstants.SUNDAY:
                dayOfWeek = "Sunday";
                break;
        }

Answer 1

很明显，它只是文档中记录的here的dateTime.dayOfWeek().getAsText();。

Answer 2

您可以使用上面的逻辑创建DateTime扩展方法，并在需要的地方使用，而不会重复整个逻辑。
