java - Log4j2 SMTP 附加程序 "Must issue a STARTTLS command first"

标签 java email smtp log4j2 smtpappender

我正在尝试通过 java 中的电子邮件发送严重性为“错误”的日志条目。 在我的 log4j2.xml 文件中，我有以下 SMTP 附加程序:

<SMTP>
name="Mail"
subject="Error Log"
to="receiver@domain.com"
from="sender@domain.com"
smtpHost="SMTP-Host"
smtpPort="587"
smtpPassword="[password]" 
smtpUsername="email@domain.com"
smtpDebug="true"
ignoreExceptions="false"
bufferSize="4"
smtpProtocol="smtp">
</SMTP>

但是当我运行我的程序(其中包含一个主要记录字符串)时，会发生以下错误:

据我了解，程序可以建立与服务器的连接，但必须首先发出 STARTTLS 命令会发生这种情况。有人可以向我解释这意味着什么以及如何解决它吗？

当我搜索错误时，我得到了一些有类似问题的帖子，但不是使用 log4j2，而是使用 java.mail，但它们没有帮助我。

我尝试使用 smtpPort="465" 和 smtpProtocol="smtps" 但在这两种情况下连接都被拒绝。

我没有更多的新想法，感谢所有帮助我的人。

最佳答案

我遇到了同样的问题，看起来 log4j2 无法处理 STARTTLS。幸运的是，log4j 在创建邮件 session 时使用系统属性。所以我的修复方法是使用

smtpProtocol="smtp"

用于 SMTP 附加程序并设置系统属性

mail.smtp.starttls.enable=true

在命令行上激活邮件 session 的 STARTTLS。您也可以使用

System.setProperty("mail.smtp.starttls.enable", "true")

在您的应用程序代码中。
