阿瓦拉拉:什么是"DateTime"? JSON日期的有效格式?

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));
    }
}
