Java后台发送邮件

一、实现思路：

1.设置连接参数

2.设置邮件相关属性

3.发送邮件

二、相关需求：

1.导入jar包：

2.设置email.properties

mail.smtp.host=smtp.163.com
mail.smtp.auth=true
userName=ashdagsjdag@163.com
password=asdkahsda

二、代码实现：

public class SendEmail {
	private static Properties props = null;
	private static Session session = null;
	private static MimeMessage message = null;
	private static Transport transport = null;
	/**
	 * 配置参数
	 * @throws IOException
	 * @throws NoSuchProviderException
	 */
	private static void init() throws IOException, NoSuchProviderException{
		props = new Properties();//设置配置文件
		props.load(SendEmail.class.getClassLoader().getResourceAsStream("email.properties"));
		session = Session.getInstance(props);
		message = new MimeMessage(session);
		transport = session.getTransport("smtp");
	}

	/**
	 * 发送邮件
	 * @param toAddress
	 * @param subject
	 * @param sendMessage
	 */
	public static void sendEmail(String toAddress,String subject,String sendMessage){

		try {
			init();
			session.setDebug(true);
			//设置发件人
			message.setFrom(new InternetAddress(props.getProperty("userName")));
			//设置收件人
			message.setRecipient(Message.RecipientType.TO, new InternetAddress(toAddress));
			//设置邮件主题
			message.setSubject(subject);
			//设置邮件内容
			message.setText(sendMessage);

			message.saveChanges();

			transport.connect(props.getProperty("userName"), props.getProperty("password"));

			transport.sendMessage(message, message.getAllRecipients());
            transport.close();

		} catch (MessagingException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

}

请指教。
