Mail依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
<version>${spring-boot-mail.version}</version>
</dependency>

通用配置application.properties:

# 设置邮箱主机
spring.mail.host=smtp.qq.com

# 设置用户名
spring.mail.username=xxxxxx@qq.com

# 设置密码，该处的密码是QQ邮箱开启SMTP的授权码而非QQ密码
spring.mail.password=pwvtabrwxogxidac

# 设置是否需要认证，如果为true,那么用户名和密码就必须的，
# 如果设置false，可以不设置用户名和密码，当然也得看你的对接的平台是否支持无密码进行访问的。
spring.mail.properties.mail.smtp.auth=true

# STARTTLS[1] 是对纯文本通信协议的扩展。它提供一种方式将纯文本连接升级为加密连接（TLS或SSL），而不是另外使用一个端口作加密通信。
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

mail.from=${spring.mail.username}
mail.to=yyyyyy@qq.com
