Spring Java 发送各种邮件_org.springframework.mail.javamail.javamailsende-优快云博客

Spring邮件抽象层的主要包为 org.springframework.mail 。它包括了发送电子邮件的主要接口 MailSender ，和 值对象 SimpleMailMessage ，它封装了简单邮件的属性如 from , to , cc , subject , text 。包里还包含一棵以 MailException 为根的checked Exception继承树，它们提供了对底层邮件系统异常的高级别抽象。要获得关于邮件异常层次的更丰富的信息，请参考Javadocs。

为了使用JavaMail中的一些特色, 比如MIME类型的信件, Spring提供了MailSender的一个子接口, 即org.springframework.mail.javamail.JavaMailSender。Spring还提供了一个回调接口org.springframework.mail.javamail.MimeMessagePreparator, 用于准备JavaMail的MIME信件。

这里简单的介绍了如何使用spring发送各种形式的邮件以及配置。

1、在src目录下建立mail.properties文件里边包含一下内容

mail.host=smtp.exmail.qq.com(建议使用这个，如果使用smtp.qq.com可能会出现安全认证的问题
mail.username=你的邮箱名
mail.password=你的邮箱密码
mail.from=发送方的邮箱

2、使用spring配置
