记录JAVA实现邮件发送

有详细描述。

入参Email    收件人邮箱

subject  邮件主题

text   邮件内容

public boolean sendEmail(String Email,String subject,String text){
        MailHost mailHost = mailMapper.selectMailHost();
        //获取发件人邮箱
        String addressFrom = mailHost.getAddressFrom();
        //获取服务器地址
        String host = mailHost.getHost();
        //获取密码
        String passWord = mailHost.getAuthCode();
        //获取邮箱传输协议
        String protocol = mailHost.getProtocol();
        try {
            //1,设置连接服务器参数配置
            Properties props = new Properties();
            props.setProperty("mail.transport.protocol",protocol);
            props.setProperty("mail.smtp.host",host);
            if (mailHost.getAuthFlag().equals("1")){
                props.setProperty("mail.smtp.auth","true");
            }else if(mailHost.getAuthFlag().equals("0")){
                props.setProperty("mail.smtp.auth","false");
            }

            //2,配置创建会话对象,用于和邮件服务器交互
            Session session = Session.getInstance(props);
            session.setDebug(true);
            //3,发送邮件信息
            MimeMessage message = new MimeMessage(session);
            message.setFrom(addressFrom);
            //设置收件人邮箱
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(Email));
            //设置主题
            message.setSubject(subject);
            message.setSentDate(new Date());
            //设置文本
            message.setText(text);
            //4,根据Session 获取邮件传输对象
            Transport transport = session.getTransport();

            //5,使用邮箱账号 密码 连接邮件服务器
            String user = addressFrom.split("@")[0];
            transport.connect(user,passWord);
            Address[] allRecipients = message.getAllRecipients();

            transport.sendMessage(message,allRecipients);
            transport.close();
        }catch (Exception e){
            log.error("发送邮件失败");
            e.printStackTrace();
            return false;
        }
        return true;
    }
