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);
}
}

复制代码

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;
}
}

复制代码

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) {
}
}
}

复制代码

希望本文所述对大家java程序设计有所帮助。
