以一个web项目为例，代码是可以移植的

首先要导入mail.jar包，然后创建自己的类

1：HTMLSender类

复制代码代码如下:

package com.txq.mail;

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.NoSuchProviderException;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

import javax.mail.internet.MimeUtility;

/**

*

* @author Administrator

*

*/

public class HTMLSender {

private MimeMessage message;

private Properties props;

private Session session;

private String name = "";

private String password = "";

public HTMLSender(String host,String name,String password)

{

this.name = name;

this.password = password;

props = System.getProperties();

props.put("mail.smtp.host", host);

props.put("mail.smtp.auth","true");

MyAuthenticator auth = new MyAuthenticator(name,password);

session = Session.getDefaultInstance(props,auth);

message = new MimeMessage(session);

new MimeMultipart();

}

public void setFrom(String from)

{

try

{

message.setFrom(new InternetAddress(from));

}

catch (AddressException e)

{

e.printStackTrace();

}

catch (MessagingException e)

{

e.printStackTrace();

}

}

public void setTo(String to)

{

try

{

message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to));

}

catch(AddressException e)

{

e.printStackTrace();

}

catch(MessagingException e)

{

e.printStackTrace();

}

}

public void setSubject(String subject)

{

try

{

message.setSubject(subject);

}

catch(Exception e)

{

e.printStackTrace();

}

}

public void setContect(String content)

{

try

{

message.setContent(content,"text/html;charset=utf-8");

}

catch(Exception e)

{

e.printStackTrace();

}

}

public boolean send()

{

try

{

Transport transport = session.getTransport("smtp");

transport.connect((String)props.get("mail.smtp.host"),name,password);

transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));

transport.close();

return true;

}

catch(NoSuchProviderException e)

{

e.printStackTrace();

return false;

}

catch(MessagingException e)

{

e.printStackTrace();

return false;

}

}

}

2：MyAuthenticator类

复制代码代码如下:

package com.txq.mail;

import javax.mail.Authenticator;

import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator{

String name;

String password;

public MyAuthenticator(String name,String pasword)

{

this.name = name;

this.password = pasword;

getPasswordAuthentication();

}

protected PasswordAuthentication getPasswordAuthentication()

{

return new PasswordAuthentication(name,password);

}

}

3：MailAction类

复制代码代码如下:

package com.txq.action;

import java.io.PrintWriter;

import com.opensymphony.xwork2.ActionSupport;

import com.txq.mail.HTMLSender;

public class MailAction extends ActionSupport {

private String email;

public String sendEmail(){

//代理主机-新浪

String host = "smtp.sina.cn";

//帐号-新浪帐号

String name = "followmusic";

//密码-新浪密码

String password = "followmusic";

//创建发送邮件对象

HTMLSender mail = new HTMLSender(host,name,password);

//发邮帐号

mail.setFrom("followmusic@sina.cn");

//收邮帐号

mail.setTo("youxiangzhanghe@qq.com");

//邮件主题

mail.setSubject("淘兴趣");

//邮件内容

mail.setContect("你的好友邀请你来淘兴趣~");

if(mail.send())

{

return SUCCESS;

}

else

{

return "error";

}

}

public String getEmail() {

return email;

}

public void setEmail(String email) {

this.email = email;

}

}
