Apache的開源項目Commons Email發送郵件

需要在代碼里面發郵件是很經常的事情，包括找回密碼，通知用戶領獎，監控報警等。

import org.apache.commons.mail.EmailAttachment;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.MultiPartEmail;

import java.net.MalformedURLException;
import java.net.URL;
public class MultiPartEmailTest {
    public static void main(String[] args) throws EmailException, MalformedURLException {
        MultiPartEmail email = new MultiPartEmail();

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

//        email.setAuthentication("youremail@qq.com", "***");//郵件服務器驗證：用戶名/密碼
        email.setCharset("UTF-8");

    email.setFrom("pony@qq.com", "馬化騰");
    email.addTo("youremail@qq.com");

    email.setSubject("加油奮斗！");
    email.setMsg("come on! 加油奮斗吧，早晚有一天你會出任CEO，迎娶白富美，走上人生巔峰！ http://www.qq.com\n\n\n pony");

    EmailAttachment attachment = new EmailAttachment();
    attachment.setPath("d:/lzl.jpg");// 本地文件
    attachment.setDisposition(EmailAttachment.ATTACHMENT);
    attachment.setDescription("林志玲1");
    attachment.setName("lzl_1");
    email.attach(attachment);

    EmailAttachment attachment2 = new EmailAttachment();
    attachment2.setURL(new URL("http://mat1.qq.com/datalib_img/star/pic/lib/2007-01-15/2007011511104716122311.jpg"));//遠程文件
    attachment2.setDisposition(EmailAttachment.ATTACHMENT);
    attachment2.setDescription("林志玲2");
    attachment2.setName("lzl_2");
    email.attach(attachment2);

    email.send();
}

}
</pre>
 Commons Email支持好幾種格式，包括簡單文本，html，帶附件等。需要的可以自己查看文檔。 

 基于smtp的協議郵件協議很簡單，大家甚至可以直接用telnet來發送，可以參考這邊文章Java Mail(一)：telnet實現發送收取郵件. 

 一般公司內網沒有驗證發送方，你可以冒充公司任何一個員工發送郵件（包括你們老板），一般外面的郵件服務器，比如qq, 126, 163等，是需要驗證密碼的。重申一遍，別用這個代碼干壞事，后果自負， 與本人無關！
