Question

我正在尝试使用Logback登录我的java应用程序。我相信我已经正确配置了它，但是当记录错误时

ch.qos.logback.classic.net.SMTPAppender中的
INFO [EMAIL] - 即将发送将SMTP消息“Testing Main”发送到[XXXX@optonline.net]

打印到控制台，之后没有打印任何其他内容，并且永远不会收到电子邮件。如果我在配置中输入了无效的smtp主机或用户名/密码，则在尝试发送时会立即失败，因此它正在建立连接。

这是为了产生测试错误而运行的代码

logger.error("Entering app");
logger.error("exiting app");

System.out.println("exiting");

非常感谢任何有关调试此问题的帮助谢谢

我也遇到了这个问题并找到了解决方案。要运行上面的代码，您必须进行一些更改：

1. Add `<STARTTLS>true</STARTTLS>` in your configuration
2. Add  <asynchronousSending>false</asynchronousSending>

Answer 2

这似乎是我使用的SMTP服务器的一个问题。我将Papercut设置为本地smtp服务器，我可以看到它收到消息

Answer 3

如果您使用 gmail 发送电子邮件，那么以下 logback 配置对我有用。

<springProperty scope="context" name="smtpHost" source="spring.mail.host" />
    <springProperty scope="context" name="smtpPort" source="spring.mail.port" />
    <springProperty scope="context" name="username" source="spring.mail.username" />
    <springProperty scope="context" name="password" source="spring.mail.password" />

<appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
    <smtpHost>${smtpHost}</smtpHost>
    <smtpPort>${smtpPort}</smtpPort>
    <SSL>true</SSL>
    <username>${username}</username>
    <password>${password}</password>
    <to>${username}</to>
    <from>${username}</from>
    <subject>Error From ERP: %logger{20} - %m</subject>

    <layout class="ch.qos.logback.classic.html.HTMLLayout"/>
    <cyclicBufferTracker class="ch.qos.logback.core.spi.CyclicBufferTracker">
        <!-- only 5 log entries on email -->
        <bufferSize>5</bufferSize>
    </cyclicBufferTracker>
</appender>

虽然我的配置存在于 application.yaml 文件中，可以看出我正试图从那里获取它们。在我的情况下，smtp 端口设置为 465。

Logback SMTPAppender不发送电子邮件
