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。
