Answer 1

您的语言环境似乎正在用逗号(,(作为小数分隔符格式化小数。

PayPal API只接受带句点(.(的数字作为十进制分隔符

Answer 2

取此行：

amount.setTotal(String.format("%.2f", total));

将%.2f更改为%.3f。最后的代码应该是这样的：

amount.setTotal(String.format("%.3f", total));

Answer 3

在我的案例中，我发送了带有非四舍五入值的SubTotal on Details：

141.750

所以我就这样四舍五入：

details.setSubtotal(subTotal.setScale(2, BigDecimal.ROUND_HALF_EVEN).toString());

(换句话说(

141.75
