Spring boot使用log4j2发送邮件

Question

我在localhost中有一个Docker SMTP服务器，下面是我的配置文件：

有人能帮我吗？

好的，我终于解决了。它每次都在工作，但是它不能识别我的应用程序日志，所以它只能使用spring framework日志名，例如：org.springframework.boot

我解决了添加一个引用SMTPapPender的新记录器的问题：

        <Logger name="com.myapp" level="all" additivity="false">
            <AppenderRef ref="AsyncMailer" level="debug" />
        </Logger>

并且在log.error（“xxx”）上发送带有日志信息的邮件。
