Java Mail学习

邮件实体类 MailInfo

package org.xfl.jmail;

import java.util.Properties;

public class MailInfo {
	private String host;// 邮件服务器域名或IP
	private String from;// 发件人
	private String port;
	private String to;// 收件人
	private String cc;// 抄送人
	private String username;// 发件人用户名
	private String password;// 发件人密码
	private String title;// 邮件的主题
	private String content;// 邮件的内容
	private boolean validate = false;

	public String getHost() {
		return host;
	}

	public void setHost(String host) {
		this.host = host;
	}

	public String getFrom() {
		return from;
	}

	public void setFrom(String from) {
		this.from = from;
	}

	public String getTo() {
		return to;
	}

	public void setTo(String to) {
		this.to = to;
	}

	public String getCc() {
		return cc;
	}

	public void setCc(String cc) {
		this.cc = cc;
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getContent() {
		return content;
	}

	public void setContent(String content) {
		this.content = content;
	}

	public String getPort() {
		return port;
	}

	public void setPort(String port) {
		this.port = port;
	}

	public boolean isValidate() {
		return validate;
	}

	public void setValidate(boolean validate) {
		this.validate = validate;
	}

	public Properties getProperty() {
		Properties prop = new Properties();
		prop.put("mail.smtp.host", this.host);
		prop.put("mail.smtp.port", this.port);
		prop.put("mail.smtp.auth", validate ? "true" : "false");    
		return prop;
	}

}

自定义验证类MyAuthenticator

package org.xfl.jmail;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator {
	 private String strUser;
	 private String strPwd;
	 public MyAuthenticator(String user, String password) {
		this.strUser = user;
	 	this.strPwd = password;
	 }
	 protected PasswordAuthentication getPasswordAuthentication() {
	    return new PasswordAuthentication(strUser, strPwd);
	 }
}

发送器类

package org.xfl.jmail;

import java.util.Date;
import java.util.Properties;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class MailSender {
	protected boolean sendMail(MailInfo mailInfo) {
		Properties prop = mailInfo.getProperty();
		MyAuthenticator auth = null;
		if (mailInfo.isValidate()) {
			auth = new MyAuthenticator(mailInfo.getUsername(),
					mailInfo.getPassword());
		}
		Session sendMailSession = Session.getDefaultInstance(prop, auth);
		try {
			// 根据session创建一个邮件消息
			Message mailMessage = new MimeMessage(sendMailSession);
			// 创建邮件发送者地址
			Address from = new InternetAddress(mailInfo.getFrom());
			// 设置邮件消息的发送者
			mailMessage.setFrom(from);
			// 创建邮件的接收者地址，并设置到邮件消息中
			Address to = new InternetAddress(mailInfo.getTo());
			mailMessage.setRecipient(Message.RecipientType.TO, to);
			// 设置邮件消息的主题
			mailMessage.setSubject(mailInfo.getTitle());
			// 设置邮件消息发送的时间
			mailMessage.setSentDate(new Date());
			// 设置邮件消息的主要内容
			String mailContent = mailInfo.getContent();
			mailMessage.setText(mailContent);
			// 发送邮件
			Transport.send(mailMessage);
			return true;
		} catch (MessagingException ex) {
			ex.printStackTrace();
		}
		return false;
	}

}

测试：

package org.xfl.jmail;

public class JavaMailMain {

	private static String user = "****@sina.com";
	private static String pwd = "****";

	public static void main(String[] args) {
			MailInfo mail = new MailInfo();
			mail.setFrom("****@sina.com");
			mail.setTo("****@qq.com");
			mail.setTitle("Java Mail test");
			mail.setContent("hello world");
			mail.setUsername(user);
			mail.setPassword(pwd);
			mail.setHost("smtp.sina.com");
			mail.setPort("25");
			mail.setValidate(true);
			MailSender jmail = new MailSender();
			if (jmail.sendMail(mail)) {
				System.out.println("ok");
			}
			else {
				System.out.println("failure");
			}
	}
