Spring 简单实现邮件发送

Spring提供了一个发送邮件的抽象层,使发送邮件实现非常简单。

下面代码需要mail.jar包,如果服务器需要认证,必须加入如下加粗代码:

源文件:SendMail.java:

package mail;

import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
import java.util.Date;
/**

public class SendMail {
 //邮件发送器
 public static String Sender(String subject, String msg, String sendTo, String fromMail, String user, String pw, String fromName, String protocol, String host, String port){
  try{
   final String username = user;
   final String pass = pw;
   //需要认证
   Properties props = new Properties();
   props.put("mail.smtp.host", host);
   props.put("mail.smtp.auth", "true");
   props.put("mail.transport.protocol", protocol);
   props.put("mail.from", fromMail);
    //创建发送器
   JavaMailSenderImpl sender = new JavaMailSenderImpl();
   sender.setHost(host);
   sender.setUsername(username);
   sender.setPassword(pass);
   //创建消息   
   MimeMessage message = sender.createMimeMessage();  
   message.addHeader("X-Mailer", "Java Mailer");
   MimeMessageHelper helper = new MimeMessageHelper(message); 
   helper.setTo(sendTo);
   helper.setFrom(fromMail, fromName);  
   helper.setSubject(subject);
   helper.setText(msg);
   helper.setSentDate(new Date());
   //开始发送
   sender.setJavaMailProperties(props);
   sender.send(message);
  }catch(Exception e){
   System.out.println("Error:" + e);
            return "Failure";
  }
  return "Success";
 }
 
 //测试
 public static void main(String args[])throws Exception
 {
  
  String subject = "测试邮件";//标题
        String sendTo = "[email protected]";//接收者邮件
        String fromMail = "[email protected]";//发送者邮件
        String user = "[email protected]";//发送者用户
        String pw = "password";//发送者邮件密码
        String fromName = "Chen";//发送者名字
        String protocol = "smtp";//协议
        String host = "smtp.my.com";//发送主机
        String port = "25";//端口
        String msg = "简单邮件发送。";//发送内容
        String ret = Sender(subject, msg, sendTo, fromMail, user, pw, fromName, protocol, host, port);
  
  System.out.println("邮件发送结果:" + ret);
    
 } 
  
}

 

使用MimeMessageHelper,可以实现Multipart email,方便添加附件和内嵌资源等。
