到目前为止唯一的解决方案是：更改 log4j2

Devtools 有时会导致类加载器问题，您可以尝试暂时删除它，看看问题是否仍然存在。

我制作了一个示例 github 项目，我在这个纯 Springboot 项目中也遇到了异常： https://github.com/robozb/SpringBoot3LogbackSmtpAppenderError

示例中的一些调试显示真正的原因如下：

可以通过向 POM 添加邮件依赖项来解决这个问题：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

事实上，没有报告实际原因并不好，我已经打开了#36645，看看我们是否可以改进这一点。

我刚刚注意到您javax.mail:javax.mail-api在上面的评论中列出了您的依赖项，您需要切换到雅加达版本。

@robozb 啊是的，这是一个有趣的小调试技巧。我添加了一个异常断点ModelHandlerException。这让我停在了AppenderModelHandler第 75 行。然后我添加了一个监视表达式，oops.printStackTrace()这让我在控制台中找到了真正的原因。
