2.认证

/**

 * 邮箱认证

 * @return

 */

private static JavaMailSenderImpl authEmail(){

    JavaMailSenderImpl javaMailSender=new JavaMailSenderImpl();

    javaMailSender.setHost(host);

    javaMailSender.setPort(port);

    javaMailSender.setUsername(email);

    javaMailSender.setPassword(pwd);

    //认证机制

    Properties properties=new Properties();

    //连接超时

    properties.setProperty("mail.smtp.connectiontimeout","10000");

    //开启认证

    properties.setProperty("mail.smtp.auth","true");

    //启动调试

    properties.setProperty("mail.debug","true");

    //设置端口

    properties.setProperty("mail.smtp.port",Integer.toString(465));

    //加密方式

    System.out.println("启用加密方式");

    properties.setProperty("mail.smtp.starttls.enable","true");

    properties.setProperty("mail.smtp.starttls.required","true");

    //是否设置ssl端口

    System.out.println("启用ssl");

    properties.setProperty("mail.smtp.socketFactory.port",prot);

    properties.setProperty("mail.smtp.socketFactory.fallback","false");

    properties.setProperty("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");

    properties.setProperty("mail.smtp.socketFactory.enable","true");

    javaMailSender.setJavaMailProperties(properties);

    return javaMailSender;

}

/**

 * 测试连接

 * @param args

 */

public static void main(String[] args) {

    JavaMailSenderImpl javaMailSender = authEmail();

    try {

        javaMailSender.testConnection();

    } catch (MessagingException e) {

        e.printStackTrace();

    }

    System.out.println("成功");

}

3.发送

private void sendEmail() throws MessagingException, IOException, ValidationException, URISyntaxException {

    JavaMailSenderImpl javaMailSender = authEmail();

    MimeMessage message = javaMailSender.createMimeMessage();

    MimeMessageHelper messageHelper = new MimeMessageHelper(message, true, "UTF-8");

    //发送人邮箱

    messageHelper.setFrom("sendEmail");

    //接收者邮箱

    String[] tos={"invit2","invit2"};

    messageHelper.setTo(tos);

    //标题

    messageHelper.setSubject("信息通知：");

    //内容

    String content = content();

    MimeMultipart multipart=new MimeMultipart();

    MimeBodyPart bodyPart=new MimeBodyPart();

    bodyPart.setContent(content,"text/html;charset=UTF-8");

    //bodyPart.setText("会议在15分钟后");

    multipart.addBodyPart(bodyPart);

    //是否加入日历

    if (true){

        String calendar = getCalendar();

        BodyPart bodyPartCal=new MimeBodyPart();

        bodyPartCal.setDataHandler(new DataHandler(

                new ByteArrayDataSource(calendar,"text/calendar;method=REQUEST;charset=\"UTF-8\"")));

        multipart.addBodyPart(bodyPartCal);

    }

    message.setContent(multipart);

    message.setSentDate(new Date());

    //保存

    message.saveChanges();

    //发送

    javaMailSender.send(message);

}

3.日历-创建日程

/**

 * 邮箱添加到日历

 * @return

 */

private String getCalendar() throws SocketException, ValidationException, URISyntaxException {

    //设置时区

    TimeZoneRegistry zoneRegistry = TimeZoneRegistryFactory.getInstance().createRegistry();

    net.fortuna.ical4j.model.TimeZone timeZone = zoneRegistry.getTimeZone("Asia/Shanghai");

    VTimeZone tz = timeZone.getVTimeZone();

    //创建日历

    net.fortuna.ical4j.model.Calendar calendar=new net.fortuna.ical4j.model.Calendar();

    calendar.getProperties().add(Version.VERSION_2_0);

    // -//Events Calendar//iCal4j 1.0//EN

    calendar.getProperties().add(new ProdId("-//Ben Fortuna//iCal4j 1.0//EN"));

    calendar.getProperties().add(CalScale.GREGORIAN);

    calendar.getProperties().add(Method.REQUEST);

    //开始时间 接收时间

    LocalDateTime currDate = LocalDateTime.now().plusDays(1L).with(LocalTime.MIN);

    LocalDateTime start = currDate.with(LocalTime.parse("11:00"));

    LocalDateTime end = currDate.with(LocalTime.parse("12:15"));

    DateTime startTime =new DateTime(start.toInstant(ZonedDateTime.now().getOffset()).toEpochMilli());

    startTime.setTimeZone(timeZone);

    DateTime endTime =new DateTime(end.toInstant(ZonedDateTime.now().getOffset()).toEpochMilli());

    endTime.setTimeZone(timeZone);

    //创建事件

    VEvent vEvent=new VEvent(startTime,endTime,"信息通知");

    //地址

    vEvent.getProperties().add(new Location("测试园区-F4"));

    //唯一标识

    vEvent.getProperties().add(new Uid(new UidGenerator("iCal4j").generateUid().getValue()));

    //时区

    vEvent.getProperties().add(tz.getTimeZoneId());

    //组织者

    Organizer organizer=new Organizer("mailto:email");

    organizer.getParameters().add(new Cn("Booked or person"));

    vEvent.getProperties().add(organizer);

    //邀请者

    String[] tos={};

    for (int i = 0; i < tos.length; i++) {

        Attendee dev = new Attendee(URI.create("mailto:"+tos[i]));

        dev.getParameters().add(Role.REQ_PARTICIPANT);

        dev.getParameters().add(new Cn("Developer"+i));

        vEvent.getProperties().add(dev);

    }

    // 重复事件

//        Recur recur = new Recur(Recur.WEEKLY, Integer.MAX_VALUE);

//        recur.getDayList().add(WeekDay.MO);

//        recur.getDayList().add(WeekDay.TU);

//        recur.getDayList().add(WeekDay.WE);

//        recur.getDayList().add(WeekDay.TH);

//        recur.getDayList().add(WeekDay.FR);

//        RRule rule = new RRule(recur);

//        vEvent.getProperties().add(rule);

    // 提醒,提前10分钟

    VAlarm valarm = new VAlarm(new Dur(0, 0, -10, 0));

    valarm.getProperties().add(new Summary("预订信息"));

    valarm.getProperties().add(Action.DISPLAY);

    valarm.getProperties().add(new Description("会议信息预订一个计划"));

    // 将VAlarm加入VEvent

    vEvent.getAlarms().add(valarm);

    // 添加事件

    calendar.getComponents().add(vEvent);

    // 验证

    calendar.validate();

    return calendar.toString();
