apache commons-email

使用commons mail时需要的jar包:
1,commons-email-1.1.jar
2,mail.jar
3,activation.jar
(在web应用里只需要commons-email包)

发送简单的文字邮件:

SimpleEmail email  =   new  SimpleEmail();

email.setHostName( " smtp.sina.com " );
email.setAuthentication( " username " ,  " password " ); // 在邮件服务商处注册的用户名和密码
email.addTo( " [email protected] " );
email.setFrom( " [email protected] " ,  " alias " );

email.setCharset( " UTF-8 " ); // gbk或gb2312,只要支持中文就行
email.setSubject( " title " );
email.setMsg( " content " );
email.send();

发送带附件的邮件:

//  Create the attachment
EmailAttachment attachment  =   new  EmailAttachment();
attachment.setPath( " mypictures/john.jpg " );
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription( " Picture of John " );
attachment.setName( " John " );

//  Create the email message
MultiPartEmail email  =   new  MultiPartEmail();
email.setHostName( " mail.myserver.com " );
email.setAuthentication( " username " ,  " password " );
email.addTo( " [email protected] " ,  " John Doe " );
email.setFrom( " [email protected] " ,  " Me " );
email.setCharset( " UTF-8 " );
email.setSubject( " The picture " );
email.setMsg( " Here is the picture you wanted " );

//  add the attachment
email.attach(attachment);

//  send the email
email.send();

创建多个EmailAttachment对象,并调用MultiPartEmail.attach();就可以发送多个附件.

发送HTML格式的邮件:

发送html格式的邮件和简单邮件的区别就在创建HtmlEmail对象
并用email.setHtmlMsg(String)或email.setMsg(String)把含有html标签的字符串赋给email对象.
HtmlEmail对象还有一个setTextMsg(String)方法,这个方法参数里的html标签会被当做普通字符处理,不会被解析成html元素.
