通过java发送特定日期的自动邮件 [英] Send automatic mail on specific date through java

问题描述

我正在使用Java邮件API通过我的java应用程序发送电子邮件。但是我想在将来的日期，即每个月/年的任何具体日期自动发送。我已经使用我的ISP的SMTP服务器发送电子邮件提到的id.I我参考了以下可用的网络示例。如何设置任何具体的日期这里。我已经尝试SimpleDateFormat并将其设置在这里，但它仍然立即发送邮件，但将其发送日期设置为提到的具体日期。有没有其他方式可以在上述日期和时间发送自动电子邮件？

  import java.util。*; 
 import javax.mail。*; 
 import javax.mail.internet。*; 
 import javax.activation。*; 
 
 //发送一个简单的单个部分，文本/纯电子邮件
 public class TestEmail {
 
 public static void main（String [] args）{ 
 
 //取代您的电子邮件地址！ 
 String to =[e-mail]; 
 String from =[e-mail]; 
 //取代您的ISP的邮件服务器！ 
 String host =smtp.yourisp.net; 
 
 //创建属性，获取会话
属性props = new Properties（）; 
 
 //如果使用静态Transport.send（），
 //需要指定哪个主机发送到
 props.put（mail.smtp.host主办）; 
 //查看场景后面发生的事情
 props.put（mail.debug，true）; 
会话session = Session.getInstance（props）; 
 
 try {
 //实例化消息
消息msg = new MimeMessage（session）; 
 
 //设置消息属性
 msg.setFrom（new InternetAddress（from））; 
 InternetAddress [] address = {new InternetAddress（to）}; 
 msg.setRecipients（Message.RecipientType.TO，address）; 
 msg.setSubject（通过Java测试电子邮件）; 
 msg.setSentDate（new Date（））; 
 
 //设置消息内容
 msg.setText（这是通过Java.\\\
+ $发送+ 
纯文本电子邮件的测试b $ b这是第2行）; 
 
 //发送消息
 Transport.send（msg）; 
} 
 catch（MessagingException mex）{
 //打印所有嵌套（链接）异常以及
 mex.printStackTrace（）; 
} 
} 
} //类结束
  

解决方案

配置 Quartz 工作。使用 cron触发器指定执行事件

I am using Java mail API to send email through my java application. But I want to send it automatically on future date i.e. any specific date of every month/year. I have used my ISP's SMTP server to send email on mentioned id.I have referred the below available example on net. How to set any specific date here.I have tried SimpleDateFormat and set it here but it still sends mail immediately but set its sent date as mentioned specific date. Is there any other way to send automatic email on mentioned date and time?

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

// Send a simple, single part, text/plain e-mail
public class TestEmail {

public static void main(String[] args) {

    // SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
    String to = "[e-mail]";
    String from = "[e-mail]";
    // SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
    String host = "smtp.yourisp.net";

    // Create properties, get Session
    Properties props = new Properties();

    // If using static Transport.send(),
    // need to specify which host to send it to
    props.put("mail.smtp.host", host);
    // To see what is going on behind the scene
    props.put("mail.debug", "true");
    Session session = Session.getInstance(props);

    try {
        // Instantiatee a message
        Message msg = new MimeMessage(session);

        //Set message attributes
        msg.setFrom(new InternetAddress(from));
        InternetAddress[] address = {new InternetAddress(to)};
        msg.setRecipients(Message.RecipientType.TO, address);
        msg.setSubject("Test E-Mail through Java");
        msg.setSentDate(new Date());

        // Set message content
        msg.setText("This is a test of sending a " +
                    "plain text e-mail through Java.\n" +
                    "Here is line 2.");

        //Send the message
        Transport.send(msg);
    }
    catch (MessagingException mex) {
        // Prints all nested (chained) exceptions as well
        mex.printStackTrace();
    }
}
}//End of class

Configure Quartz Job for it. Use cron trigger to specify the execution event
