利用javamail發送郵件執行個體

最近在學習使用javamail發送郵件

使用javamail發送郵件，要先導入activation.jar，mail.jar兩個包

使用的sina郵箱往163的兩個郵箱發送郵件

下面是簡單的測試源碼

MailConfig .java代碼 

package com.test;

public class MailConfig {
	
	private String from;//發件人
	private String to;//收件人
	private String host;//發送郵件伺服器
	private String password;//密碼
	
	public String getFrom() {
		return from;
	}
	public void setFrom(String from) {
		this.from = from;
	}
	public String getTo() {
		return to;
	}
	public void setTo(String to) {
		this.to = to;
	}
	public String getHost() {
		return host;
	}
	public void setHost(String host) {
		this.host = host;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
}
           

SendMail .java

package com.test;

import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class SendMail {
	
	public void sendMail(String subject,String content,MailConfig mailConfig,String fileNames){
		Properties props = new Properties();
		props.put("mail.smtp.host", mailConfig.getHost());
		
		Session session = Session.getDefaultInstance(props,null);
		Message message = new MimeMessage(session);
		
		try{
			message.setFrom(new InternetAddress(mailConfig.getFrom()));
			message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(mailConfig.getTo()));
			message.setSubject(subject);
			
			BodyPart bodyPart = new MimeBodyPart();
			bodyPart.setText(content);
			Multipart multipart = new MimeMultipart();
			multipart.addBodyPart(bodyPart);
			
			if(!(fileNames==null||fileNames.length()==0)){
				String [] s = fileNames.split(",");
				for(String fileName:s){
					BodyPart messageBodyPart = new MimeBodyPart();
					DataSource dataSource = new FileDataSource(fileName);
					messageBodyPart.setDataHandler(new DataHandler(dataSource));
					messageBodyPart.setFileName(dataSource.getName());
					multipart.addBodyPart(messageBodyPart);
				}
			}
			
			message.setContent(multipart);
			Transport transport = session.getTransport("smtp");
			transport.connect(mailConfig.getHost(), mailConfig.getFrom(), mailConfig.getPassword());
			transport.sendMessage(message, message.getAllRecipients());
			transport.close();
			
		}catch(Exception e){
			e.printStackTrace();
		}
	}
}
           

MailTest.java

package com.test;

public class MailTest {
	
	public static void main(String[] args) {
		
		String subject = "測試";
		String content = "郵件測試,帶附件的測試！";
		
		MailConfig mailConfig = new MailConfig();
		mailConfig.setHost("smtp.sina.com.cn");//smtp伺服器，我這用的是sina的smtp
		mailConfig.setFrom("[email protected]");//發件人郵箱
		mailConfig.setTo("[email protected],[email protected]");//多個收件人使用逗号分隔
		mailConfig.setPassword("xxxxxx");//發件人密碼
		
		SendMail mail = new SendMail();
		
		//這是帶附件的郵件發送，如果沒有郵件，可以置fileNames=""或者fileNames=null
		String fileNames = "d:/sof.sql,d:/myeclipse_templates_8.5.rar";
		mail.sendMail(subject, content, mailConfig, fileNames);
		
		System.out.println("發送成功！");
	}
