使用Java發送郵件附件

Question

我想用java和g郵件發送電子郵件我已經將我的文件存儲在雲上以及我想作爲附件發送給我的郵件的存儲文件中。

它應該將該文件添加到此郵件中，而不是這些文件的鏈接。

我如何發送這樣的附件？

Answer 1

工作的代碼，我用Java郵件1.4.7罐子

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

public class MailProjectClass { 

public static void main(String[] args) { 

    final String username = "your.mail.id@gmail.com"; 
    final String password = "your.password"; 

    Properties props = new Properties(); 
    props.put("mail.smtp.auth", true); 
    props.put("mail.smtp.starttls.enable", true); 
    props.put("mail.smtp.host", "smtp.gmail.com"); 
    props.put("mail.smtp.port", "587"); 

    Session session = Session.getInstance(props, 
      new javax.mail.Authenticator() { 
       protected PasswordAuthentication getPasswordAuthentication() { 
        return new PasswordAuthentication(username, password); 
       } 
      }); 

    try { 

     Message message = new MimeMessage(session); 
     message.setFrom(new InternetAddress("from.mail.id@gmail.com")); 
     message.setRecipients(Message.RecipientType.TO, 
       InternetAddress.parse("to.mail.id@gmail.com")); 
     message.setSubject("Testing Subject"); 
     message.setText("PFA"); 

     MimeBodyPart messageBodyPart = new MimeBodyPart(); 

     Multipart multipart = new MimeMultipart(); 

     messageBodyPart = new MimeBodyPart(); 
     String file = "path of file to be attached"; 
     String fileName = "attachmentName"; 
     DataSource source = new FileDataSource(file); 
     messageBodyPart.setDataHandler(new DataHandler(source)); 
     messageBodyPart.setFileName(fileName); 
     multipart.addBodyPart(messageBodyPart); 

     message.setContent(multipart); 

     System.out.println("Sending"); 

     Transport.send(message); 

     System.out.println("Done"); 

    } catch (MessagingException e) { 
     e.printStackTrace(); 
    } 
    } 
}

使用Spring框架，您可以添加多個附件：

package com.mkyong.common; 


import javax.mail.MessagingException; 
import javax.mail.internet.MimeMessage; 

import org.springframework.core.io.FileSystemResource; 
import org.springframework.mail.MailParseException; 
import org.springframework.mail.SimpleMailMessage; 
import org.springframework.mail.javamail.JavaMailSender; 
import org.springframework.mail.javamail.MimeMessageHelper; 

public class MailMail 
{ 
    private JavaMailSender mailSender; 
    private SimpleMailMessage simpleMailMessage; 

    public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) { 
     this.simpleMailMessage = simpleMailMessage; 
    } 

    public void setMailSender(JavaMailSender mailSender) { 
     this.mailSender = mailSender; 
    } 

    public void sendMail(String dear, String content) { 

     MimeMessage message = mailSender.createMimeMessage(); 

     try{ 
     MimeMessageHelper helper = new MimeMessageHelper(message, true); 

     helper.setFrom(simpleMailMessage.getFrom()); 
     helper.setTo(simpleMailMessage.getTo()); 
     helper.setSubject(simpleMailMessage.getSubject()); 
     helper.setText(String.format(
      simpleMailMessage.getText(), dear, content)); 

     FileSystemResource file = new FileSystemResource("/home/abdennour/Documents/cv.pdf"); 
     helper.addAttachment(file.getFilename(), file); 

     }catch (MessagingException e) { 
     throw new MailParseException(e); 
     } 
     mailSender.send(message); 
     } 
}

首先，你必須下載從雲 看看如何做到這一點的ADF框架（相同的代碼工作，爲任何基於Java框架）文件

http://www.awasthiashish.com/2013/06/download-file-from-url-using-oracle-adf.html

然後附上該文件中使用abosolute路徑

郵寄

對於ü不知道的原因，當我發送電子郵件到我的Gmail地址時，接受的答案部分起作用。我有附件，但沒有電子郵件的文字。

如果你想附着和文本嘗試此基礎上公認的答案：

Properties props = new java.util.Properties(); 
    props.put("mail.smtp.host", "yourHost"); 
    props.put("mail.smtp.port", "yourHostPort"); 
    props.put("mail.smtp.auth", "true");    
    props.put("mail.smtp.starttls.enable", "true"); 


    // Session session = Session.getDefaultInstance(props, null); 
    Session session = Session.getInstance(props, 
       new javax.mail.Authenticator() { 
       protected PasswordAuthentication getPasswordAuthentication() { 
        return new PasswordAuthentication("user", "password"); 
       } 
       }); 


    Message msg = new MimeMessage(session); 
    try { 
     msg.setFrom(new InternetAddress(mailFrom)); 
     msg.setRecipient(Message.RecipientType.TO, new InternetAddress(mailTo)); 
     msg.setSubject("your subject"); 

     Multipart multipart = new MimeMultipart(); 

     MimeBodyPart textBodyPart = new MimeBodyPart(); 
     textBodyPart.setText("your text"); 

     MimeBodyPart attachmentBodyPart= new MimeBodyPart(); 
     DataSource source = new FileDataSource(attachementPath); // ex : "C:\\test.pdf" 
     attachmentBodyPart.setDataHandler(new DataHandler(source)); 
     attachmentBodyPart.setFileName(fileName); // ex : "test.pdf" 

     multipart.addBodyPart(textBodyPart); // add the text part 
     multipart.addBodyPart(attachmentBodyPart); // add the attachement part 

     msg.setContent(multipart); 


     Transport.send(msg); 
    } catch (MessagingException e) { 
     LOGGER.log(Level.SEVERE,"Error while sending email",e); 
    }
