采用apache commons email实现邮件的发送

1. 发送简单的文本邮件。注意setHostName 与setAuthenticator 中的信息必须对应

   public static void main(String[] args) {
   		try {
   			Email email = new SimpleEmail();
   			email.setHostName("smtp.yeah.net");// 发送方的服务器地址
   			email.addTo("[e-mail]");// 接受方的邮箱地址
   			// 验证发送人信息
   			email.setAuthenticator(new DefaultAuthenticator(
   					"username", "password"));
   			// 设置发送人
   			email.setFrom("[e-mail]");
   			// 设置邮件标题
   			email.setSubject("TestMail");
   			// 设置邮件内容
   			email.setMsg("This is a test mail ... :-)");
   
   			email.send();
   		} catch (Exception e) {
   			e.printStackTrace();
   		}
   	}

    
2. 发送带附件的邮件

   public static void main(String[] args) {
   		//创建附件信息 
   		EmailAttachment attachment = new EmailAttachment(); 
   		attachment.setPath("f:\\b1737e2dd042fd0d1f3089f4.gif");
   		attachment.setDisposition(EmailAttachment.ATTACHMENT);
   		attachment.setDescription("Picture of John");
   		attachment.setName("b1737e2dd042fd0d1f3089f4.gif");
   		// 创建邮件信息
   		MultiPartEmail email = new MultiPartEmail();
   		try{
   			email.setDebug(true);
   			email.setHostName("smtp.yeah.net");
   			email.setAuthenticator(new DefaultAuthenticator("username", "password"));
   			email.addTo("[e-mail]");
   			email.setFrom("[e-mail]");
   			email.setSubject("The picture");
   			email.setMsg("Here is the picture you wanted"); 
   			// 添加附件
   			email.attach(attachment); 
   			// 发送邮件 
   			email.send();
   		}catch(EmailException e){
   			e.printStackTrace();
   		}
   	}
