怎样用JavaMail实现邮件的自动回复和定时发送

60 Random randT = new Random(System.currentTimeMillis());

61 String title = titles[randT.nextInt(titles.length)];

62 return title;

63 }

64 //产生文本内容，文本内容由四部分随机组合得到。

触发器的代码：

复制代码

1 import org.quartz.CronScheduleBuilder;

2 import org.quartz.JobBuilder;

3 import org.quartz.JobDetail;

4 import org.quartz.Scheduler;

5 import org.quartz.Trigger;

6 import org.quartz.TriggerBuilder;

7 import org.quartz.impl.StdSchedulerFactory;

8 import java.util.Random;

9 public class CronTriggerExample

10 {

11 public static void main( String[] args ) throws Exception

12 {

13 //创建工作对象

14 JobDetail job = JobBuilder.newJob(MailJob.class)

15 .withIdentity("dummyJobName", "group1").build();

16 //为了立即测试，可以使用下面的代码，每隔5秒钟执行一次

17 //int secDelta = 5;

18 //Trigger trigger = TriggerBuilder

19 // .newTrigger()

20 // .withIdentity("dummyTriggerName", "group1")

21 // .withSchedule(

22 // CronScheduleBuilder.cronSchedule("0/" + secDelta + " * * * * ?"))

23 // .build();

24 //在每天早上的9点多（不超过3分钟）执行

25 Random rand = new Random(System.currentTimeMillis());

26 int secDelta = rand.nextInt(60 * 3);

27 //创建触发器对象

28 Trigger trigger = TriggerBuilder

29 .newTrigger()

30 .withIdentity("dummyTriggerName", "group1")

31 .withSchedule(

32 CronScheduleBuilder.cronSchedule(secDelta + " 0 9 ? * SUN-SAT"))

33 .build();

34

35 Scheduler scheduler = new StdSchedulerFactory().getScheduler();

36 scheduler.start();

37 //将触发器与工作关联起来

38 scheduler.scheduleJob(job, trigger);

39 }

40 }

发邮件依赖的包：activation.jar，mail.jar

将发邮件依赖的包和quartz下载得到的lib路径下的jar包全部放在mylib路径下，mylib路径与java文件位于同一个目录。编译和运行时，可以使用命令：

set classpath=mylib/*;.;

javac CronTriggerExample.java

java CronTriggerExample

用java写一个邮件发送代码

public boolean mainto()

{

boolean flag = true;

//建立邮件会话

Properties pro = new Properties();

pro.put("mail.smtp.host","smtp.qq点抗 ");//存储发送邮件的服务器

pro.put("mail.smtp.auth","true"); //通过服务器验证

Session s =Session.getInstance(pro); //根据属性新建一个邮件会话

//s.setDebug(true);

//由邮件会话新建一个消息对象

MimeMessage message = new MimeMessage(s);

//设置邮件

InternetAddress fromAddr = null;

InternetAddress toAddr = null;

try

{

fromAddr = new InternetAddress(451144426+"@qq点抗 "); //邮件发送地址

message.setFrom(fromAddr); //设置发送地址

toAddr = new InternetAddress("12345367@qq点抗 "); //邮件接收地址

message.setRecipient(Message.RecipientType.TO, toAddr); //设置接收地址

message.setSubject(title); //设置邮件标题

message.setText(content); //设置邮件正文

message.setSentDate(new Date()); //设置邮件日期

message.saveChanges(); //保存邮件更改信息

Transport transport = s.getTransport("smtp");

transport.connect("smtp.qq点抗 ", "451144426", "密码"); //服务器地址，邮箱账号，邮箱密码

transport.sendMessage(message, message.getAllRecipients()); //发送邮件

transport.close();//关闭

}

catch (Exception e)

{

e.printStackTrace();

flag = false;//发送失败

}

return flag;

}

这是一个javaMail的邮件发送代码，需要一个mail.jar
