这篇文章主要介绍了Java使用JavaMail发送邮件的方法,结合实例形式分析了Java使用JavaMail实现邮件发送的具体步骤与相关实现代码,需要的朋友可以参考下

本文实例讲述了Java使用JavaMail发送邮件的方法。分享给大家供大家参考，具体如下：

代码一、Email_Autherticator.java 服务器验证代码

				?

									import javax.mail.Authenticator;

									import javax.mail.PasswordAuthentication;

									public class Email_Autherticator extends Authenticator {

									  String username = "你邮箱的用户名";

									  String password = "你邮箱的密码";

									  public Email_Autherticator() {

									 super();

									  }

									  public Email_Autherticator(String user,String pwd){

									 super();

									 username = user;

									 password = pwd;

									  }

									  public PasswordAuthentication getPasswordAuthentication(){

									 return new PasswordAuthentication(username,password);

									  }

									}

代码二、Mail.java 发送邮件的代码

				?

									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 = "254173774@qq.com";

									  private String mail_from = "hackboyo@126.com";

									  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 = "我的邮件";

									  public void sendMail() throws SendFailedException{

									 try {

									   Properties props = new Properties();//获取系统环境

									   Authenticator auth = new Email_Autherticator();//进行邮件服务用户认证

									   props.put("mail.smtp.host", host);

									   props.put("mail.smtp.auth", "true");

									   System.out.println(props);

									   Session session = Session.getDefaultInstance(props,auth);

									   //设置session,和邮件服务器进行通讯

									   MimeMessage message = new MimeMessage(session);

									   message.setContent("Hello","text/plain");//设置邮件格式

									   message.setSubject(mail_subject);//设置邮件主题

									   message.setText(mail_body);//设置邮件内容

									   message.setHeader(mail_head_name, mail_head_value);//设置邮件标题

									   message.setSentDate(new Date());//设置邮件发送时期

									   Address address = new InternetAddress(mail_from,personalName);

									   message.setFrom(address);//设置邮件发送者的地址

									   Address toaddress = new InternetAddress(mail_to);//设置邮件接收者的地址

									   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;

									  }

									}

代码三、Test.java 测试发送邮件的代码

				?

									public class Test {

									  public static void main(String[] args) {

									 Mail m = new Mail();

									 try {

									   m.sendMail();

									 } catch (Exception e) {

									 }

									  }

									}
