javamail验证失败Authentication failed的原因以及解决办法

javamail邮件开发:
验证失败的原因和解决办法:
发送成功之后再控制台打印的内容

1.先申请一个邮箱,然后开通pop3/smtp服务
这里我用的是网易的163邮箱
在开启POP3/SMTP服务的时候会让你输入一个授权码,这个授权码后面会用到.

2.代码的书写:

@Test    public void testJavaMail() throws Exception{        Properties props = new Properties();        props.put("mail.smtp.host", "smtp.163.com");//指定邮件的发送服务器地址        props.put("mail.smtp.auth", "true");//服务器是否要验证用户的身份信息        Session session = Session.getInstance(props);//得到Session        session.setDebug(true);//代表启用debug模式，可以在控制台输出smtp协议应答的过程        //创建一个MimeMessage格式的邮件        MimeMessage message = new MimeMessage(session);        //设置发送者        Address fromAddress = new InternetAddress("[e-mail]");//邮件地址        message.setFrom(fromAddress);//设置发送的邮件地址        //设置接收者        Address toAddress = new InternetAddress("[e-mail]");//要接收邮件的邮箱        message.setRecipient(RecipientType.TO, toAddress);//设置接收者的地址        //设置邮件的主题        message.setSubject("xxxx");        //设置邮件的内容        message.setText("xxxxxxxx");        //保存邮件        message.saveChanges();        //得到发送邮件的服务器(这里用的是smtp服务器)        Transport transport = session.getTransport("smtp");        //发送者的账号连接到smtp服务器上  @163.com可以不写transport.connect("smtp.163.com","[e-mail]","授权码");         //发送信息        transport.sendMessage(message, message.getAllRecipients());        //关闭服务器通道        transport.close();    }

3.验证失败的原因:

    //发送者的账号连接到smtp服务器上  @163.com可以不写transport.connect("smtp.163.com","[e-mail]","授权码"); 

应该填的是授权码,而不是你邮箱的登陆密码,要注意

4.发送成功之后再控制台打印的内容
