使用javax.mail发送邮件时,报错java.lang.ClassNotFoundException: com.sun.mail.util.MessageRemovedIOException

原因:

所引入的javax.mail的jar包,不包含com.sun.mail.util.MessageRemovedIOException类

解决:

可以更换齐全的javax.mail的jar包,或者额外导入com.sun.mail 的jar包

<dependency>
   <groupId>javax.mail</groupId>
   <artifactId>mail</artifactId>
   <version>1.4</version>
</dependency>

<dependency>
   <groupId>com.sun.mail</groupId>
   <artifactId>javax.mail</artifactId>
   <version>1.5.6</version>
</dependency>
