//使用JavaMail发送邮件的5个步骤
try{
//1、创建session
Session session = Session.getInstance(prop);
//开启Session的debug模式,这样就可以查看到程序发送Email的运行状态
session.setDebug(true);
//2、通过session得到transport对象
Transport ts = session.getTransport();
//3、使用邮箱的用户名和密码连上邮件服务器,发送邮件时,发件人需要提交邮箱的用户名和密码给smtp服务器,用户名和密码都通过验证之后才能够正常发送邮件给收件人。
ts.connect("smtp.qq.com", "QQ号", "授权码"); // qq的密码需要开启授权码,把授权码放到这里就行
//4、创建邮件
Message message = createSimpleMail(session);
//5、发送邮件
ts.sendMessage(message, message.getAllRecipients());
ts.close();
}catch (Exception e){
e.printStackTrace();
}
}
public MimeMessage createSimpleMail(Session session)
throws Exception {
//创建邮件对象
MimeMessage message = new MimeMessage(session);
//指明邮件的发件人
message.setFrom(new InternetAddress(senderAddress));
//指明邮件的收件人,现在发件人和收件人是一样的,那就是自己给自己发
message.setRecipient(Message.RecipientType.TO, new InternetAddress(targetAddress));
//邮件的标题
message.setSubject(subject);
//邮件的文本内容
message.setContent(content, "text/html;charset=UTF-8");
//返回创建好的邮件对象
return message;
