我尝试使用Java8 LocalDateTime解析日期字符串但没有成功。
例外情况是: DateTimeParseException:Text' 28-APR-2015 01:25:00 PM'无法在索引3解析
要解析的字符串是: 28-APR-2015 01:25:00 PM ,我目前使用的模式是 dd-LLL-yyyy hh:mm: ss a
我哪里错了?
谢谢
添加示例代码:
String text = "28-APR-2015 01:25:00 PM";
DateTimeFormatter fromatter = DateTimeFormatter.ofPattern("dd-LLL-yyyy hh:mm:ss a");
try {
String out = LocalDateTime.parse(text, formatter)
System.out.println(out);
} catch (DateTimeParseException e) {
e.printStackTrace();
}
使用@Florin的回复解决:
DateTimeFormatter tertiaryFormatter = new DateTimeFormatterBuilder()
.parseCaseInsensitive().parseLenient().appendPattern("dd-LLL-yyyy hh:mm:ss a").toFormatter();

LLL
英文将 Apr
asList("MMM", "LLL").forEach(ptrn
-> System.out.println(ptrn + ": " + ofPattern(ptrn, Locale.ENGLISH).format(Month.APRIL))
);
Locale.setDefault(Locale.ENGLISH);
String textM = "28-Apr-2015 01:25:00 PM";
DateTimeFormatter formatterM = DateTimeFormatter.ofPattern("dd-MMM-yyyy hh:mm:ss a");
System.out.println(LocalDateTime.parse(textM, formatterM));
String textL = "28-4-2015 01:25:00 PM";
DateTimeFormatter formatterL = DateTimeFormatter.ofPattern("dd-LLL-yyyy hh:mm:ss a");
System.out.println(LocalDateTime.parse(textL, formatterL));

请运行此代码段 - 它会向您解释很多:
DateTimeFormatter
如果您需要使用 APR ,则需要使用DateTimeFormatterBuilder
构建自己的parseCaseInsensitive
并设置body {
margin: 0px;
padding: 0px;
background-color: #fff;
}
.marquee {
margin: 10px;
padding: 10px;
}
span {
display: inline-block;
margin:0px;
padding:0px;
}
.container{
display: flex;
justify-content: center;
list-style-type: none;
}
.ind-cont {
background-color: #000;
width: 200px;
height: 100px;
margin: 0px;
padding:0px;
}
.txtcolor {
color: #fff;
}
.txtcolorb {
color: #aaa;
}
.ind-name {
margin: 20px;
}
.capital {
float: right;
margin: 20px;
}
.floatright {
float: right;
margin: 10px;
margin-right: 20px;
}
.one-share {
margin: 10px;
margin-left: 20px;
}

The problem is because of your time pattern issue. you need make sure your time format could matching with the pattern.
