SpringBoot邮件发送
邮件发送是一个非常常见的功能,注册时的身份认证、重要通知发送等都会用到邮件发送。Sun公司提供了JavaMail用来实现邮件发送,但是配置烦琐,Spring 中提供了JavaMailSender 用来简化邮件配置,Spring Boot则提供了MailSenderAutoConfiguration 对邮件的发送做了进一步简化。
发送前的准备
使用QQ邮箱发送邮件,首先要申请开通POP3/SMTP服务或者IMAP/SMTP服务。SMTP全称为Simple Mail Transfer Protocol,译作简单邮件传输协议,它定义了邮件客户端软件与SMTP服务器之间,以及SMTP服务器与SMTP服务器之间的通信规则。也就是说,aaa@qq 用户先将邮件投递到腾讯的SMTP服务器,这个过程就使用了SMTP协议,然后腾讯的SMTP服务器将邮件投递到网易的SMTP服务器,这个过程依然使用了SMTP协议,SMTP服务器就是用来接收邮件的。而POP3全称为Post Office Protocol3,译作邮局协议,它定义了邮件客户端与POP3服务器之间的通信规则。该协议在什么场景下会用到呢?当邮件到达网易的SMTP服务器之后,111@163 用户需要登录服务器查看邮件,这个时候就用上该协议了:邮件服务商会为每一个用户提供专门的邮件存储空间,SMTP服务器收到邮件之后,将邮件保存到相应用户的邮件存储空间中,如果用户要读取邮件,就需要通过邮件服务商的POP3邮件服务器来完成。至于IMAP协议,则是对POP3协议的扩展,功能更强,作用类似。
