无法从类 javax.activation.MailcapCommandMap- Spring boot 访问类 com.sun.activation.registries.LogSupport

问：

我正在尝试使用 Spring boot 中的邮件服务通过电子邮件发送 OTP，但出现错误 -

无法从类 javax.activation.MailcapCommandMap 访问类 com.sun.activation.registries.LogSupport（com.sun.activation.registries.LogSupport 和 javax.activation.MailcapCommandMap 位于加载程序“app”的未命名模块中）

在 pom.xml- 中的依赖项下添加了
