或将邮件内容及邮件地址等封装为EmailContent的bean实体

通过Controll而接受.

下面是我的邮件主机配置,大家可以拿去用

##上传文件限制大小

spring.servlet.multipart.max-file-size=10MB

spring.servlet.multipart.max-request-size=10MB

##发送email设置

spring.application.name=spring-boot-mail

spring.mail.host=smtp.126.com

spring.mail.username=hostinbj@126.com

spring.mail.password=1314520jy

spring.mail.default-encoding=UTF-8

##邮件主机地址

mail.fromMail.addr=hostinbj@126.com

spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

#邮件端口

spring.mail.properties.mail.smtp.socketFactory.port=465

spring.mail.properties.mail.smtp.auth=true

spring.mail.properties.mail.smtp.starttls.enable=true

spring.mail.properties.mail.smtp.starttls.required=true
