我有路由“imap://%s@%s?password=%s&folderName=%s&unseen=true&delete=true&skipFailedMessage=true”来轮询电子邮件并跳过失败的电子邮件。此属性 skipFailedMessage=true 未得到尊重，或者我不了解它的用途。
我正在阅读来自 5 个具有不同占位符的不同邮箱的电子邮件，但当我遇到“org.apache.camel.RuntimeCamelException:无法提取正文，原因是:BASE64Decoder:编码流中出现错误:在之后找到有效的 base64 字符”时，没有读取任何电子邮件其中一封电子邮件上有一个填充字符 (=)”。如果失败的邮件被删除，我只能阅读不同邮箱中的所有其他电子邮件。请帮忙。我尝试了版本 2.17.3 和 2.18，两者的行为方式相同。
这是堆栈跟踪:

最佳答案
该错误来自 JavaMail，可能是由于消息格式不正确造成的。您可以通过将系统属性“mail.mime.base64.ignoreerrors”设置为“true”来告诉JavaMail忽略此类错误。
