用commons-email-1.1.jar实现发邮件功能:

今天在Apache网站上下载commons-lang jar文件时突然看到commons-email-1.1.jar这个项目jar文件，看了看user guide确实比JDK提供的好多了，简单的几行代码就实现了发邮件的功能，以前实现过一个纯JavaMail带附件发邮件功能，代码复杂不说，现在回过头来都懒得看（主要是WEB项目注释少）。

    贴上TEST代码看看，简单、清晰。只要稍加修改（邮件服务器地址、名称、密码）就可以了
简单邮件的发送：

package com.bulktree.mail;

import java.util.Date;

import org.apache.commons.mail.EmailException;

import org.apache.commons.mail.SimpleEmail;

publicclass SimpleMailTest {

    publicstaticvoid main(String[] args) throws EmailException {

       SimpleEmail email = new SimpleEmail();

       //设置发送主机的服务器地址

       email.setHostName("smtp.163.com");

       //设置收件人邮箱

       email.addTo("[e-mail]","bulktree");

       //发件人邮箱

       email.setFrom("[e-mail]", "bulktree");

       //如果要求身份验证，设置用户名、密码，分别为发件人在邮件服务器上注册的用户名和密码

       email.setAuthentication("bulktree", "123456");

       //设置邮件的主题

       email.setSubject("Hello, This is My First Email Application");

       //邮件正文消息

       email.setMsg("I am bulktree This is JavaMail Application");

       email.send();

       System.out.println("The SimpleEmail send sucessful!!!");

    }

}

带附件邮件发送：

package com.bulktree.mail;

import java.net.MalformedURLException;

import java.net.URL;

import org.apache.commons.mail.EmailAttachment;

import org.apache.commons.mail.EmailException;

import org.apache.commons.mail.MultiPartEmail;

publicclass AttachmentMailTest {

    publicstaticvoid main(String[] args) throws EmailException, MalformedURLException {

//     创建一个Email附件

       EmailAttachment emailattachment = new EmailAttachment();

       emailattachment.setPath("/biao_05.jpg");

//     emailattachment.setURL(new URL("http://www.blogjava.net/bulktree/picture/bulktree.jpg"));

       emailattachment.setDisposition(EmailAttachment.ATTACHMENT);

       emailattachment.setDescription("This is Smile picture");

       emailattachment.setName("bulktree");

//     创建一个email

       MultiPartEmail multipartemail = new MultiPartEmail();

       multipartemail.setHostName("smtp.163.com");

       multipartemail.addTo("[e-mail]", "bulktree");

       multipartemail.setFrom("[e-mail]", "bulktree");

       multipartemail.setAuthentication("bulktree", "123456");

       multipartemail.setSubject("This is a attachment Email");

       multipartemail.setMsg("this a attachment Eamil Test");

       //添加附件

       multipartemail.attach(emailattachment);

       //发送邮件

       multipartemail.send();

       

       System.out.println("The attachmentEmail send sucessful!!!");

    }

}

备注：需要commons-email-1.1.jar和mail.jar这两个包！
出现乱码的原因是SimpleEmail类中对setMsg(String msg)重载的时候，并没有指定charset字符集× setContent(msg, "text/plain");
