java 发邮件实例

1)发送纯邮件的代码：

 

public class SimpleMailTest {
	/**
	 * @param args
	 * @throws EmailException 
	 */
	public static void main(String[] args) throws EmailException {
	//	无附件邮件发送
	 * SimpleEmail email = new SimpleEmail();
	       //设置发送主机的服务器地址
	       email.setHostName("smtp.qq.com");
	       //设置收件人邮箱
	       email.addTo("***@163.com","xx");
	       //发件人邮箱
	       email.setFrom("1231231@qq.com", "eeee");
	       //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("username", "password");
	       //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 Test This is JavaMail Application");
	       email.send();
	       System.out.println("The SimpleEmail send sucessful!!!");
	}

 2.带附件发送邮箱代码：

public static void main(String[] args) throws EmailException {
//         创建一个Email附件
           EmailAttachment emailattachment = new EmailAttachment();
           emailattachment.setPath("D:\\xinqing.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.qq.com");
           multipartemail.addTo("dddd@163.com","ddddd");
           multipartemail.setFrom("23232323@qq.com", "eeee");
          multipartemail.setAuthentication("username", "password");
           multipartemail.setSubject("测试带附件邮件");
           multipartemail.setMsg("有图片附件吗？");
           //添加附件
           multipartemail.attach(emailattachment);
           //发送邮件
           multipartemail.send();
           System.out.println("The attachmentEmail send sucessful!!!");
    }

  *注意：

      首先确保自己的邮箱设置开启POP3/SMTP 服务，一般邮箱使用服务要收费，最好使用QQ邮箱（用前记得设置）
