使用JavaMail发送邮件

1.导入activation.jar和mail.jar连个文件

2.关键代码如下：

package com.test;

import java.util.Properties;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;



public class SendEmial {

  public static void main(String[] args) {
    
    //创建邮件会话
    Properties prop = new Properties();   
    prop.put("mail.transport.protocol","smtp");
    prop.put("mail.smtp.port","25");
    prop.put("mail.smtp.host", "127.0.0.1");
    Session s = Session.getDefaultInstance(prop);
    
    //新建一个消息对象
    Message msg = new MimeMessage(s);
    
    try {
      //发信人
      Address from = new InternetAddress("[e-mail]");
      //收信人
      Address to = new InternetAddress("[e-mail]");      
      msg.setFrom(from);
      msg.setRecipient(RecipientType.TO, to);
      
      msg.setSubject("标题");//标题
      msg.setText("ddddddddddddddddddddddddddddddddddddddddBB"); //邮件内容
      
      Transport.send(msg); //发送邮件     
      
    } catch (Exception e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
    
  }
}
