『JAVA基础』使用JavaMail发邮件的实例

早上来上班，SIR要我写个类发邮件！

 

现在这里工作，都是用AJAX搞页面的，都好久没写什么类了！弄了好久才弄出来，现在共享出来，希望对各位有用了

 

 

 

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 = "[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) {
    
  }
    }
}

 

源代码已在附件中了，同时，还需要二个jar包，activation.jar和mail.jar，需要用的请下载吧
