英文:
Datetime format in java for date like 'Jun 3, 2020 5:04:05 PM'
问题
在Java中是否有一种格式用于解析日期，例如像'Jun 3, 2020 5:04:05 PM'这样的格式？因为我正在使用JEE创建一个应用程序，在持久化数据时，我的日志文件中出现了以下消息：<Text 'Jun 3, 2020 5:04:05 PM' 无法在索引0处解析>。
英文:
Is there an format in java for parsing date such as 'Jun 3, 2020 5:04:05 PM' because i'm creating an app in JEE and i got ths message <Text 'Jun 3, 2020 5:04:05 PM' could not be parsed at index 0> in my log file when persisting data

I recommend you use java.time.LocalDateTime and DateTimeFormatter.ofPattern instead of using the outdated java.util.Date and SimpleDateFormat. Check this to learn more about the modern date/time API.
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;
public class Main {
public static void main(String[] args) {
// Define format
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMM d, yyyy h:mm:ss a", Locale.US);
// Date/time string
String strDate = "Jun 3, 2020 5:04:05 PM";
// Parse the date/time string into LocalDateTime
LocalDateTime ldt = LocalDateTime.parse(strDate, formatter);
// Display ldt.toString()
System.out.println(ldt);
// Display `ldt` in the specified format
System.out.println(formatter.format(ldt));
}
}
Output:
2020-06-03T17:04:05
Jun 3, 2020 5:04:05 PM

如果我理解你的意思正确的话：
String dString = "2020年6月3日 下午5:04:05";
SimpleDateFormat formatter = new SimpleDateFormat("yyyy年M月d日 a h:mm:ss", Locale.CHINA);
Date date = formatter.parse(dString);
编辑：
处理地区信息：
new SimpleDateFormat("yyyy年M月d日 a h:mm:ss", Locale.US);
你也可以查看 LocalDateTime 和 DateTimeFormatter。
英文:
If I understand you correctly:
String dString = "Jun 3, 2020 5:04:05 PM"
SimpleDateFormat formatter = new SimpleDateFormat("MMM dd, yyyy HH:mm:ss aa");
Date date = formater.parse(dString);
EDIT:
Dealing with locale:
new SimpleDateFormat("MMM dd, yyyy HH:mm:ss aa", Locale.US)
You can also look at LocalDateTime and DateTimeFormatter
