jmail 如何发送附件？

用javamail收发附件的例子
------------------------EmailAuthenticator.java---------------------
package com.xxx.helper.javamail;

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


public class EmailAuthenticator extends javax.mail.Authenticator
{
private String userName = null;
private String password = null;

public void setUserName(String aUserName)
{
this.userName = aUserName;
}

public void setPassword(String aPassword)
{
this.password = aPassword;
}

public EmailAuthenticator()
{
super();
}

public EmailAuthenticator(String aUserName, String aPassword)
{
super();
setUserName(aUserName);
setPassword(aPassword);
}

//一定要有这个方法，它是在需要身份验证时自动被调用的
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(this.userName, this.password);
}
}
