JavaMail发送邮件

JavaMail发送邮件，已经过测试

1. OssMailSenderInfo类，包含需要发送的邮件信息，包括发送者和接收者的信息

package com.jesse.onlineshop.util;

import java.util.Properties;

public class OssMailSenderInfo {

	private String mailServerHost;
	private String mailServerPort = "25";
	// 邮件发送者的地址
	private String fromAddress;
	// 邮件接收者的地址
	private String toAddress;
	// 登陆邮件发送服务器的用户名和密码
	private String userName;
	private String password;
	// 是否需要身份验证
	private boolean validate = false;
	// 邮件主题
	private String subject;
	// 邮件的文本内容
	private String content;

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

	public String getMailServerHost() {
		return mailServerHost;
	}

	public void setMailServerHost(String mailServerHost) {
		this.mailServerHost = mailServerHost;
	}

	public String getMailServerPort() {
		return mailServerPort;
	}

	public void setMailServerPort(String mailServerPort) {
		this.mailServerPort = mailServerPort;
	}

	public String getFromAddress() {
		return fromAddress;
	}

	public void setFromAddress(String fromAddress) {
		this.fromAddress = fromAddress;
	}

	public String getToAddress() {
		return toAddress;
	}

	public void setToAddress(String toAddress) {
		this.toAddress = toAddress;
	}

	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 boolean isValidate() {
		return validate;
	}

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

	public String getSubject() {
		return subject;
	}

	public void setSubject(String subject) {
		this.subject = subject;
	}

	public String getContent() {
		return content;
	}

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

}

2. OssAuthenticator类，在使用需要登录验证的邮箱服务器发送邮件时，提供发送者用户和密码信息

package com.jesse.onlineshop.util;

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

public class OssAuthenticator extends Authenticator {
	
	String userName = null;
	String password = null;

	public OssAuthenticator() {
	}

	public OssAuthenticator(String username, String password) {
		this.userName = username;
		this.password = password;
	}

	protected PasswordAuthentication getPasswordAuthentication() {
		return new PasswordAuthentication(userName, password);
	}
}

3. OssMailSender类，发送邮件，包括文本格式和HTML格式邮件

package com.jesse.onlineshop.util;

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

import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class OssMailSender {
	/**
	 * 以文本格式发送邮件
	 * 
	 * @param mailInfo
	 *            待发送的邮件的信息
	 */
	public boolean sendTextMail(OssMailSenderInfo mailInfo) {
		// 判断是否需要身份认证
		OssAuthenticator authenticator = null;
		Properties pro = mailInfo.getProperties();
		if (mailInfo.isValidate()) {
			// 如果需要身份认证，则创建一个密码验证器
			authenticator = new OssAuthenticator(mailInfo.getUserName(),
					mailInfo.getPassword());
		}
		// 根据邮件会话属性和密码验证器构造一个发送邮件的session
		Session sendMailSession = Session
				.getDefaultInstance(pro, authenticator);
		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.getFromAddress());
			// 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.getToAddress());
			mailMessage.setRecipient(Message.RecipientType.TO, to);
			// 设置邮件消息的主题
			mailMessage.setSubject(mailInfo.getSubject());
			// 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;
	}

	/**
	 * 以HTML格式发送邮件
	 * 
	 * @param mailInfo
	 *            待发送的邮件信息
	 */
	public boolean sendHtmlMail(OssMailSenderInfo mailInfo) {
		// 判断是否需要身份认证
		OssAuthenticator authenticator = null;
		Properties pro = mailInfo.getProperties();
		// 如果需要身份认证，则创建一个密码验证器
		if (mailInfo.isValidate()) {
			authenticator = new OssAuthenticator(mailInfo.getUserName(),
					mailInfo.getPassword());
		}
		// 根据邮件会话属性和密码验证器构造一个发送邮件的session
		Session sendMailSession = Session
				.getDefaultInstance(pro, authenticator);
		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.getFromAddress());
			// 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.getToAddress());
			// Message.RecipientType.TO属性表示接收者的类型为TO
			mailMessage.setRecipient(Message.RecipientType.TO, to);
			// 设置邮件消息的主题
			mailMessage.setSubject(mailInfo.getSubject());
			// 设置邮件消息发送的时间
			mailMessage.setSentDate(new Date());
			// MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象
			Multipart mainPart = new MimeMultipart();
			// 创建一个包含HTML内容的MimeBodyPart
			BodyPart html = new MimeBodyPart();
			// 设置HTML内容
			html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");
			mainPart.addBodyPart(html);
			// 将MiniMultipart对象设置为邮件内容
			mailMessage.setContent(mainPart);
			// 发送邮件
			Transport.send(mailMessage);
			return true;
		} catch (MessagingException ex) {
			ex.printStackTrace();
		}
		return false;
	}
}

4. 测试

package com.jesse.onlineshop.util;

import org.junit.BeforeClass;
import org.junit.Ignore;
import org.junit.Test;

public class OssMailSenderTest {
	
	private static OssMailSenderInfo mailInfo;
	private static OssMailSender sms;

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		String subject = "Change Your Password - From OSS";
		String content = "Change Your Password Now.<br>www.baidu.com";
		mailInfo = new OssMailSenderInfo();
		mailInfo.setMailServerHost("smtp.qq.com");
		mailInfo.setMailServerPort("25");
		mailInfo.setValidate(true);
		mailInfo.setUserName("*********@qq.com");
		mailInfo.setPassword("*********");
		mailInfo.setFromAddress("*********@qq.com");
		mailInfo.setToAddress("*********@qq.com");
		mailInfo.setSubject(subject);
		mailInfo.setContent(content);
		sms = new OssMailSender();
	}

	@Test
	public void testSendTextMail() {
		sms.sendTextMail(mailInfo);// 发送文体格式
	}

	@Ignore
	@Test
	public void testSendHtmlMail() {
		sms.sendHtmlMail(mailInfo);// 发送html格式
	}

}
