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("bulktree@126.com","bulktree");        //发件人邮箱        email.setFrom("bulktree@163.com", "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("bulktree@126.com", "bulktree");        multipartemail.setFrom("bulktree@163.com", "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!!!");     } }

运行本例子程序需要commons-email-1.1.jar和mail.jar这两个包！
