Avalara:json 日期的 "DateTime" 有效格式是什么?

Avalara: What is a "DateTime" valid format for the json date?

A​​valara 的正确 JSON 日期格式是什么?以下代码:

 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();

抛出未指示正确格式的异常:

如有疑问,请阅读源代码。 看起来 com.google.gson.DefaultDateTypeAdapter 有几个默认日期格式,它将尝试在 deserializeToDate 中使用。所以请确保您使用的是其中之一。

大部分日期格式来自 java.text.DateFormat

还要检查 AvaTax-REST-V2

的来源

如果您在编辑器中链接了源代码,那么我建议在堆栈跟踪中的几个地方放置一个断点以查看发生了什么。一个好的候选人当然会在 deserializeToDate 中。


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));
    }
}

简答: 升级你对 gson 的依赖,你的代码没有任何问题。我转到更新的版本并修复了错误:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.5</version>
</dependency>
