Springboot发送邮件

引入jar

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-autoconfigure -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>

<!-- mail -->
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.1</version>
</dependency>

如果不是springboot应用，可以参考这里实例化sender即可
`
org.springframework.boot.autoconfigure.mail.MailSenderAutoConfiguration

`

配置

配置application.properties或者application.yml

3. #mail
4. #电子邮件地址
5. spring.mail.host=smtp.163.com
6. #邮箱服务器默认端口
7. spring.mail.port=25
8. #协议
9. spring.mail.protocol=smtp
10. #邮箱账号名
11. spring.mail.username=***@163.com
12. #授权密码,不是登录密码，在  设置->POP3/IMAP/SMTP->客户端授权密码
13. spring.mail.password=***

这里是授权码，不是登陆密码，授权码的设置可以参考：163邮箱授权码设置
