DateUtils.parseDate exception

javadatetimeapache-commons-dateutils

提问by spentak

I can't seem to get this to work, it says Unknown pattern character - "T"

我似乎无法让它工作,它说未知模式字符 - “T”

Unable to parse the date 2011-07-22T12:01:34.9455820

无法解析日期 2011-07-22T12:01:34.9455820

Date theDate = DateUtils.parseDate(notif.dateStr, new String[]{"yyyy-MM-ddTHH:mm:ss.S"});

This won't work either(which is what I was doing first, and in this case it just gave a parse exception):

这也不起作用(这是我首先要做的,在这种情况下它只是给出了一个解析异常):

Date theDate = DateUtils.parseDate(notif.dateStr);

Where is my error?

我的错误在哪里?

Try yyyy-MM-dd'T'HH:mm:ss.Sas the format pattern. Example:-

尝试yyyy-MM-dd'T'HH:mm:ss.S作为格式模式。例子:-

public static void main(String[] args) {
        String date = "2011-07-22T12:01:34.9455820";
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.S");
        try {
            Date dt = format.parse(date);
            System.out.println(dt.toString()); //prints Fri Jul 22 14:39:09 CDT 2011
        } catch (ParseException e) {
            e.printStackTrace();
        }

    }

Your error is that you are not providing a pattern that matches the format.

您的错误是您没有提供与格式匹配的模式。

parseDate

public static Date parseDate(String str,
                             String[] parsePatterns)
                      throws ParseException

Parses a string representing a date by trying a variety of different parsers.

The parse will try each parse pattern in turn. A parse is only deemed sucessful
if it parses the whole of the input string. If no parse patterns match, 
a ParseException is thrown.
