最近调试的javamail

最近在写mail系统，在网上搜索了一些代码，整理如下，供大家参考

package cn.com.andy.mail;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;

public class MailServer extends Authenticator{
 public Session session;
 protected PasswordAuthentication authentication;
 
  public MailServer(String user, String host,String pass)
   {
     this(user,host,pass, true);
   }
   /**
    *
    * @param user
    * @param host
    * @param pass
    * @param debug
    *
    *  @ 【用户连接邮件服务器基本验证】
    */
   public MailServer(String user,String host, String pass, boolean debug)
   {
     authentication = new PasswordAuthentication(user, pass);
     Properties props = System.getProperties();
     props.put("mail.user", user);
     props.put("mail.host", host);
     props.put("mail.password", pass);
     props.put("mail.debug", debug ? "true" : "false");
     props.put("mail.store.protocol", "imap");
     props.put("mail.transport.protocol", "smtp");
     session = Session.getInstance(props, this);

   }

  /**
   * @功能 【没有认证的邮件发送，方便确认邮件发送】
   * @param user
   * @param host
   */
  public MailClient(String user,String host)
  {
   Properties props = new Properties();
     props.put("mail.user", user);
     props.put("mail.host", host);
     props.put("mail.store.protocol", "pop3");
     props.put("mail.transport.protocol", "smtp");
     session = Session.getInstance(props, this);
  }

 

 

   
   public PasswordAuthentication getPasswordAuthentication()
   {
     return authentication;
   }
}
