本文實例講述了Java使用JavaMail發送郵件的方法。分享給大家供大家參考，具體如下：
代碼一、Email_Autherticator.java 服務器驗證代碼
import javax.mail.Authenticator;import javax.mail.PasswordAuthentication;public class Email_Autherticator extends Authenticator { String username = "你郵箱的用戶名"; String password = "你郵箱的密碼"; public Email_Autherticator() { super(); } public Email_Autherticator(String user,String pwd){ super(); username = user; password = pwd; } public PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(username,password); }}代碼二、Mail.java 發送郵件的代碼
import java.util.Date;import java.util.Properties;import javax.mail.Address;import javax.mail.Authenticator;import javax.mail.Message;import javax.mail.SendFailedException;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;public class Mail { private String host = "smtp.126.com"; private String mail_head_name = "this is head of this mail"; private String mail_head_value = "this is head of this mail"; private String mail_to = "[email protected]"; private String mail_from = "[email protected]"; private String mail_subject = "this is the subject of this test mail"; private String mail_body = "this is mail_body of this test mail"; private String personalName = "我的郵件"; public void sendMail() throws SendFailedException{ try { Properties props = new Properties();//獲取系統環境Authenticator auth = new Email_Autherticator();//進行郵件服務用戶認證props.put("mail.smtp.host", host); props.put("mail.smtp.auth", "true"); System.out.println(props); Session session = Session.getDefaultInstance(props,auth); //設置session,和郵件服務器進行通訊MimeMessage message = new MimeMessage(session); message.setContent("Hello","text/plain");//設置郵件格式message.setSubject(mail_subject);//設置郵件主題message.setText(mail_body);//設置郵件內容message.setHeader(mail_head_name, mail_head_value);//設置郵件標題message.setSentDate(new Date());//設置郵件發送時期Address address = new InternetAddress(mail_from,personalName); message.setFrom(address);//設置郵件發送者的地址Address toaddress = new InternetAddress(mail_to);//設置郵件接收者的地址message.addRecipient(Message.RecipientType.TO,toaddress); System.out.println(message); Transport.send(message); System.out.println("Send Mail Ok!"); } catch (Exception e) { e.printStackTrace(); } //return flag; }}代碼三、Test.java 測試發送郵件的代碼
public class Test { public static void main(String[] args) { Mail m = new Mail(); try { m.sendMail(); } catch (Exception e) { } }}希望本文所述對大家Java程序設計有所幫助。
