问题描述
Avalara的正确JSON日期格式是什么?以下代码:
What is the correct JSON date format for Avalara? The following code:
TransactionModel transaction = new TransactionBuilder(client, "COMPANY", DocumentType.SalesOrder, "myCompany.")
.withDate(Calendar.getInstance().getTime())
.withAddress(TransactionAddressType.SingleLocation, null, null, null, null, null, zipCode, "US")
.withLine( new BigDecimal(100.0), new BigDecimal(1), "P0000000")
.Create();
引发一个异常,该异常表示格式不正确:
throws an exception that does not indicate the correct format:

推荐答案
如有疑问,请阅读源代码.看来com.google.gson.DefaultDateTypeAdapter
有几种默认日期格式,它将尝试在deserializeToDate
中使用.因此,请确保您正在使用其中之一.
When in doubt, read the source.It looks like com.google.gson.DefaultDateTypeAdapter
has a couple default date formats that it will try to use in deserializeToDate
. So make sure you are using one of those.
大多数日期格式来自java.text.DateFormat
还要检查 AvaTax-REST-V2
如果在编辑器中链接了源,那么我建议在堆栈跟踪中的几个位置放置一个断点,以查看发生了什么.当然,deserializeToDate
是一个不错的候选人.
If you have the source linked in your editor, then I recommend putting a breakpoint at a few places in the stack trace to see what's happening. One good candidate would be in deserializeToDate
of course.
DefaultDateTypeAdapter.java
/**
* List of 1 or more different date formats used for de-serialization attempts. The first of them is
* used for serialization as well.
*/
private final List<DateFormat> dateFormats = new ArrayList<DateFormat>();
DefaultDateTypeAdapter(Class<? extends Date> dateType) {
this.dateType = verifyDateType(dateType);
dateFormats.add(DateFormat.getDateTimeInstance(DateFormat.DEFAULT, DateFormat.DEFAULT, Locale.US));
if (!Locale.getDefault().equals(Locale.US)) {
dateFormats.add(DateFormat.getDateTimeInstance(DateFormat.DEFAULT, DateFormat.DEFAULT));
}
if (JavaVersion.isJava9OrLater()) {
dateFormats.add(PreJava9DateFormatProvider.getUSDateTimeFormat(DateFormat.DEFAULT, DateFormat.DEFAULT));
}
}
DefaultDateTypeAdapter(Class<? extends Date> dateType, String datePattern) {
this.dateType = verifyDateType(dateType);
dateFormats.add(new SimpleDateFormat(datePattern, Locale.US));
if (!Locale.getDefault().equals(Locale.US)) {
dateFormats.add(new SimpleDateFormat(datePattern));
}
}
DefaultDateTypeAdapter(Class<? extends Date> dateType, int style) {
this.dateType = verifyDateType(dateType);
dateFormats.add(DateFormat.getDateInstance(style, Locale.US));
if (!Locale.getDefault().equals(Locale.US)) {
dateFormats.add(DateFormat.getDateInstance(style));
}
if (JavaVersion.isJava9OrLater()) {
dateFormats.add(PreJava9DateFormatProvider.getUSDateFormat(style));
}
}
public DefaultDateTypeAdapter(int dateStyle, int timeStyle) {
this(Date.class, dateStyle, timeStyle);
}
public DefaultDateTypeAdapter(Class<? extends Date> dateType, int dateStyle, int timeStyle) {
this.dateType = verifyDateType(dateType);
dateFormats.add(DateFormat.getDateTimeInstance(dateStyle, timeStyle, Locale.US));
if (!Locale.getDefault().equals(Locale.US)) {
dateFormats.add(DateFormat.getDateTimeInstance(dateStyle, timeStyle));
}
if (JavaVersion.isJava9OrLater()) {
dateFormats.add(PreJava9DateFormatProvider.getUSDateTimeFormat(dateStyle, timeStyle));
}
}
