jar

compile('org.springframework.boot:spring-boot-starter-mail')
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-velocity:1.7')

yml

spring.mail.host=smtp.qq.com
[email protected]
spring.mail.password=xxx //注意  qq邮箱的话 必须开启POP3/SMTP服务
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
