本文介绍了使用javamail API发送带有附件的电子邮件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
当我发送没有附件的电子邮件时,我收到电子邮件,但是当我添加附件我没有收到任何内容,我没有收到任何错误信息。
这是我使用的代码:
public void send()throws AddressException,MessagingException {
//系统属性
属性props = new Properties();
props.put(mail.smtp.localhost,localhost);
props.put(mail.smtp.host,Configurations.getInstance()。email_serverIp);
/ *
*创建一些属性并获取默认会话
* /
session = Session.getDefaultInstance(props,null);
// session
会话session = Session.getInstance(道具,null);
消息消息= new MimeMessage(session);
message.setFrom(new InternetAddress(zouhaier.mhamdi@gmail.com));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(zouhaier.mhamdi@gmail.com));
message.setSubject(Testing Subject);
message.setText(PFA);
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
generateCsvFile(/ tmp / test.csv);
messageBodyPart = new MimeBodyPart();
String file =/tmp/test.csv;
String fileName =test.csv;
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);
}
private static void generateCsvFile(String sFileName)
{
try
{
FileWriter writer = new FileWriter(sFileName);
writer.append(DisplayName);
writer.append(',');
writer.append(Age);
writer.append(',');
writer.append(你的名字);
writer.append(',');
writer.append('\\\
');
writer.append(邹);
writer.append(',');
writer.append(26);
writer.append(',');
writer.append(zouhaier);
//生成任何你想要的数据
writer.flush();
writer.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
如何更正?
解决方案
- 禁用您的防病毒
因为你有这样的警告
尝试此代码...它帮助您....
public class SendMail {
public SendMail()throws MessagingException {
String host =smtp.gmail.com;
String Password =............;
String from =XXXXXXXXXX@gmail.com;
String toAddress =YYYYYYYYYYYYYY@gmail.com;
String filename =C:/SendAttachment.java;
//获取系统属性
属性props = System.getProperties();
props.put(mail.smtp.host,主机);
props.put(mail.smtps.auth,true);
props.put(mail.smtp.starttls.enable,true);
会话session = Session.getInstance(props,null);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO,toAddress);
message.setSubject(JavaMail附件);
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(这里是文件);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
try {
传输tr = session.getTransport(smtps);
tr.connect(host,from,Password);
tr.sendMessage(message,message.getAllRecipients());
System.out.println(Mail Sent Successful);
tr.close();
} catch(SendFailedException sfe){
System.out.println(sfe);
}
}
public static void main(String args []){
try {
SendMail sm = new SendMail();
} catch(MessagingException ex){
Logger.getLogger(SendMail.class.getName())。log(Level.SEVERE,null,ex);
}
}
}
I am trying to send an email with an attachment file in Java.
When I send the email without an attachment I receive the email, but when I add the attachment I don't receive anything and I don't get any error messages.
This is the code I am using:
public void send () throws AddressException, MessagingException{
//system properties
Properties props = new Properties();
props.put("mail.smtp.localhost", "localhost");
props.put("mail.smtp.host",Configurations.getInstance().email_serverIp);
/*
* create some properties and get the default Session
*/
session = Session.getDefaultInstance(props, null);
//session
Session session = Session.getInstance(props, null);
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("zouhaier.mhamdi@gmail.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("zouhaier.mhamdi@gmail.com"));
message.setSubject("Testing Subject");
message.setText("PFA");
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
generateCsvFile("/tmp/test.csv");
messageBodyPart = new MimeBodyPart();
String file = "/tmp/test.csv";
String fileName = "test.csv";
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");
}
private static void generateCsvFile(String sFileName)
{
try
{
FileWriter writer = new FileWriter(sFileName);
writer.append("DisplayName");
writer.append(',');
writer.append("Age");
writer.append(',');
writer.append("YOUR NAME");
writer.append(',');
writer.append('\n');
writer.append("Zou");
writer.append(',');
writer.append("26");
writer.append(',');
writer.append("zouhaier");
//generate whatever data you want
writer.flush();
writer.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
How can I correct this?
