Java使用JavaMail发送邮件的方法

Java使用JavaMail发送邮件的方法

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) {

}

}

}

希望本文所述对大家Java程序设计有所帮助。
