Question

尝试使用日期和时间处理此字符串：

2015-10-23T00:00:00+03:00

使用此代码：

String transactionDateValue = getNodeValue(nodeList, i, "transactionDate");
DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd hh:mm:ss ZZZ");
DateTime jodaTime = dateTimeFormatter.parseDateTime(transactionDateValue);
DateTimeFormatter resultFormat = DateTimeFormat.forPattern("dd/MM/yyyy HH:mm:ss");

这是错误：

java.lang.IllegalArgumentException: Invalid format: "2015-10-23T00:00:00+03:00" is malformed at "T00:00:00+03:00"

我怀疑我的错误接近ZZZ参数，但无法解决。我也尝试过参数ZZZZ，ZZ，但是没有修复它。

Answer 1

这是因为您尝试解析的字符串包含T，而不是格式字符串。

您正在尝试解析标准ISO 8601格式的字符串。您不需要为此设置自定义日期格式字符串，因为默认情况下Joda Time已经支持此格式。只是做：

DateTime jodaTime = DateTime.parse(transactionDateValue);

Answer 2

您的格式必须是：

DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ssZ");

它必须与日期字符串完全相同，固定值由单引号转义且没有其他空格。此外，您必须使用HH 24小时格式化。 hh是12小时格式，它从1开始，12月结束

Joda时间：格式无效。数据格式不正确
