Log4j2 SMTP-Appender“必须首先发出STARTTLS命令”

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，我具有以下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>

但是当我运行程序（由一个主记录字符串组成）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，但是Must issue a STARTTLS command first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吗？

当我搜索错误时，我收到了一些类似问题的帖子，但不是关于log4j2的，而是关于java.mail的，他们没有帮助我。

我尝试使用smtpPort="465"和smtpProtocol="smtps"，但是在两种情况下，连接都被拒绝。

我再也没有新的想法了，感谢所有帮助我的人。

答案 0 :(得分：1)

我遇到了同样的问题，看来log4j2无法处理STARTTLS。幸运的是，log4j在创建邮件会话时使用系统属性。所以我的解决方法是使用

smtpProtocol =“ smtp”

用于SMTP附加程序并设置系统属性

mail.smtp.starttls.enable = true

在命令行上按

激活邮件会话的STARTTLS。您也可以使用

System.setProperty（“ mail.smtp.starttls.enable”，“ true”）

在您的应用程序代码中。
