Question

我正在使用Springframework的 JavaMailSenderImpl 类从Java程序发送电子邮件，它在我的本地程序中运行良好，但是在生产环境中，我间歇性地遇到异常

java.io.FileNotFoundException: class path resource 
                                  [org/springframework/mail/javamail/mime.types] 
                                   cannot be opened because it does not exist

我研究并检查了堆栈跟踪，发现此异常是从org.springframework.mail.javamail.ConfigurableMimeFileTypeMap类的createFileTypeMap方法：Source Code of ConfigurableMimeFileTypeMap

中引发的

堆栈跟踪：

有人可以帮助我解决该问题，还是只向我指出正确的方向进行操作。

IllegalStateException：无法加载指定的mime类型映射文件[org / springframework / mail / javamail / mime.types]
