eclipse3.6\plugins下就有这两个jar包

解决办法：

   javamail

   /technetwork/java/

   jaf：JavaBeans Activation Framework

   /technetwork/java/javase/downloads/#download

2. 引用jar包

gradle引用-

 [group: '',name: 'activation',version: '1.1'],
 [group: '',name: 'mail',version: '1.4']

mavn引用-

 <artifactId>activation</artifactId>
 <version>1.1</version>
</dependency>
<dependency>
 <groupId></groupId>
 <artifactId>mail</artifactId>
 <version>1.4</version>
</dependency>

springBoot引用-
