我正在尝试使用AWS SES Java SDK发送带有excel附件的电子邮件。我正在遵循AWS提供的代码模板。 https://docs.aws.amazon.com/ses/latest/DeveloperGuide/examples-send-raw-using-sdk.html
但是我正在获取javax.mail.internet.ParseException。知道这里发生了什么吗？

这是堆栈跟踪。

答案 0 :(得分：1)
您复制了从文件中设置附件的代码，并将其更改为从字节数组中设置附件的代码，但是ByteArrayDataSource没有名称，因此在为附件设置文件名时将其设置为null，这就是导致问题。将调用更改为att.setFileName以设置非空文件名。
