javaMail发送邮件(支持单发、群发)
1.所需夹包:javaMail.jar 、activation.jar
2.实现步骤:
(1).定义一个邮件消息类；
(2).定义一个服务器邮箱登录验证信息类；
(3).定义一个邮件发送类(核心类)
3.具体代码：

5.mail.properties文件,可以根据你自己的需要设置相应的用户邮箱和密码
[email protected] mail.password=123456
6.注意：使用qq邮箱发送邮件需要设置SMTP开启服务
第一步，看图操作如下:
打开QQ邮箱，在设置－帐户，然后再看下图示：
把：POP3/SMTP服务，IMAP/SMTP服务,Exchange服务，CardDAV/CalDAV服务都选择上，保存这样，便可以轻松使用邮箱客户端来收发QQ邮件了！相关OUTLOOK设置如下：
可以看到，填写好接收邮件服务器：pop.qq.com,发送邮件服务器：smtp.qq.com;然后用户名与密码，设置好了后，便可以收QQ邮件了；
