乔达时间：格式无效。数据格式错误

Question

正在尝试使用日期和时间处理此字符串：

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

通过使用此代码：

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"

我怀疑我的错误在ZZZ参数附近，但无法解决。我还尝试了参数 ZZZZ、ZZ，但并没有解决问题。

Answer 1

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一样，固定值用单引号转义并且没有额外的空格。另外你必须使用 HHfor 24 hours 格式。 hh 是 12 小时格式，从 1 开始到 12 结束

Answer 2

发生这种情况是因为您尝试解析的字符串包含 T，它不在格式字符串中。

您正在尝试解析标准 ISO 8601 格式的字符串。您不需要自定义日期格式字符串，因为 Joda Time 默认已经支持这种格式。只是做：

DateTime jodaTime = DateTime.parse(transactionDateValue);

乔达时间：格式无效。数据格式错误

Joda Time: Invalid format. Data is malformed
