1.需要的jar包
2.具体实现方法
1.设置邮箱主机、需要认证、邮箱协议
Properties pro=new Properties();
pro.setProperty("mail.host", "smtp.qq.com");
pro.setProperty("mail.smtp.auth", "true");
pro.setProperty("mail.transport.protocol", "smtp");
2.设置校验器
Authenticator auth=new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("[email protected]","qzeagwfnyxvgjgff");
}
};
3.设置套接层，是为了保证协议以及运输的安全可靠性
MailSSLSocketFactory sf=new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
pro.put("mail.smtp.ssl.enable", "true");
pro.put("mail.smto.ssl.SocketFactory", sf);
4.创建一封新邮件
//创建session
Session session=Session.getInstance(pro,auth);
session.setDebug(true);
//创建一份邮件
MimeMessage mime=new MimeMessage(session);
//填写发送人
mime.setFrom(new InternetAddress("[email protected]"));
//填写接收人
mime.setRecipients(RecipientType.TO,"[email protected]");
//设置主题
mime.setSubject("hello");
//设置正文
mime.setContent("hello，你好！","text/html;charset=utf-8");
Transport.send(mime);
System.out.println("发送成功");
Java发送带附件邮件的方法
只需要在设置正文那里注释掉，然后改成：
//发送带附件的邮件
MimeMultipart list =new MimeMultipart();
//创建body主体放置内容
MimeBodyPart b1=new MimeBodyPart();
b1.attachFile(new File("C:\\Users\\Administrator\\Desktop\\7.jpg"));
//中文转码
b1.setFileName(MimeUtility.encodeText("蜡笔小新耍流氓.jpg"));
list.addBodyPart(b1);
MimeBodyPart b2=new MimeBodyPart();
b2.setContent("hello，你好！","text/html;charset=utf-8");
list.addBodyPart(b2);
mime.setContent(list);
Transport.send(mime);
System.out.println("发送成功");
