最近闲的没事， 写了个使用javaMail 发送邮件的小程序
1：新建maven 项目
2：导入jar包依赖
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.5.2</version>
</dependency>
3：直接贴代码实现发送邮件了

// 移走集合中的所有元素

filepath.add("F:/51/2.jpg"); //
sendMail("接收邮件账号,接收邮件账号,接收邮件账号",

}
}
附：这里使用的是163邮箱， 使用腾讯QQ 邮箱没成功，不是报530 就是535 的 不知道为何，我也开通了POP3/SMTP服务
有成功的小伙伴可以给我留个言，或者直接投稿到我专题页OK ，谢谢，希望互相学习，一起进步
