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("[email protected]");//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("[email protected]");//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","[email protected]","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","xxxx@163.com","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
