javaMail 的邮件发送包括了抄送（CC），密送（BCC）采用springBoot

首先加代码配置文件来一个

mail.properties

mail.smtp.host=smtp.qq.com
mail.smtp.port=465
mail.smtp.SSLport=587
mail.smtp.starttlsEnable=true
mail.smtp.auth=true
mail.smtp.account=11036128@qq.com
mail.smtp.password=qrqzbcfslyhaai
mail.smtp.timeout=50000
mail.smtp.connectiontimeout=50000
mail.smtp.nickname=ewe

首先要去腾讯qq的设置===》账户》》开通授权码，第三方登陆需要授权码当成密码使用

然后在springboot引入这个配置文件

依赖maven加的是

<!-- email -->
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.5.4</version>
</dependency>
