使用javax.mail包中的api发送邮件大致有5个步骤
1、继承Authenticator类重写getPasswordAuthentication方法。用于登录校验。2、创建一个Properties对象用于存放SMTP服务器地址、端口号3、用步骤1和2得到的对象创建一个Session对象相当于邮箱登录4、创建一个MimeMessage设置发件人、收件人、抄送人、主题、内容添加附件5、Transport发送邮件
二、关于邮件协议和端口
常用的电子协议协议有SMTP、POP3、IMAP4它们都隶属于TCP/IP簇默认状态下分别通过TCP端口25、110和143建立连接。
发送邮件基于SMTP协议。下面列出了常用的邮件服务器地址和端口。

3.1. QQ邮箱 3.2. 163邮箱 四、实战发送邮件
4.1. 引入依赖 dependencygroupIdjavax.mail/groupIdartifactIdmail/artifactIdversion1.4/version/dependencydependencygroupIdjunit/groupIdartifactIdjunit/artifactIdversion4.9/versionscopetest/scope/dependency4.2. 方法重写
继承Authenticator并重写getPasswordAuthentication方法
