本文介绍了一个Java邮件服务接口的设计及其实现细节，包括发送单个邮件、批量邮件及带附件的批量邮件等功能。该服务利用Spring框架进行配置，并通过线程发送邮件以提高效率。

1、服务接口


package com.*.email.service;

/**
 * Description : 邮件相关服务接口. 

 * Create Time : 2013年12月2日 上午10:08:42 

 * Copyright : Copyright (c) 2010 - 2013 All rights reserved. 

 * 
 * @author Mr Yan
 * @version 1.0
 */
public interface EmailService {


	/**
	 * 发送邮件
	 * @param mailto		收件邮箱
	 * @param fromEmail		发送邮箱
	 * @param text			内容
	 * @param title			标题
	 * @throws Exception
	 */
	public void sendMail(String mailto, String fromEmail, String text, String title) throws Exception;


	/**
	 * 批量下发邮件
	 * @param mailto		收件邮箱
	 * @param fromEmail		发送邮箱
	 * @param text			内容
	 * @param title			标题
	 * @throws Exception
	 */
	public void sendBatchMail(String[] mailto, String fromEmail, String text, String title) throws Exception;


	/**
	 * 批量下发邮件待附件
	 * @param mailto		收件邮箱
	 * @param fromEmail		发送邮箱
	 * @param text			内容
	 * @param title			标题
	 * @param filePath		附件
	 * @throws Exception
	 */
	public void sendBatchMailWithFile(String[] mailto, String fromEmail, String text, String title, String[] filePath) throws Exception;

}

2、服务接口实现


package com.*.email.service.impl;

import java.util.ArrayList;
import java.util.List;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.annotation.Resource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.mail.internet.MimeUtility;

import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;

import com.*.email.service.EmailService;

/**

 */
@Service
public class EmailServiceImpl implements EmailService{

	@Resource(name = "javaMailSender")
	private JavaMailSenderImpl javaMailSender;

	class EmailThread extends Thread {
		private final MimeMessage mimeMessage;
		public EmailThread(MimeMessage mimeMessage) {
			this.mimeMessage = mimeMessage;
		}
		@Override
		public void run() {
			javaMailSender.send(mimeMessage);
		}

	}

	@Override
	public void sendMail(String mailto, String fromEmail, String text, String title) throws Exception {
		fromEmail = javaMailSender.getUsername();

		MimeMessage mimeMessage = javaMailSender.createMimeMessage();
		MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
		messageHelper.setFrom(new InternetAddress(fromEmail));
		messageHelper.setSubject(title);
		messageHelper.setText(text, true);
		messageHelper.setTo(new InternetAddress(mailto));
		mimeMessage = messageHelper.getMimeMessage();

		EmailThread et = new EmailThread(mimeMessage);
		et.start();

	}

	@Override
	public void sendBatchMail(String[] mailto, String fromEmail, String text, String title) throws Exception {

		MimeMessage mimeMessage = javaMailSender.createMimeMessage();
		MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
		messageHelper.setFrom(new InternetAddress(fromEmail));
		messageHelper.setSubject(title);
		messageHelper.setText(text, true);

		List<InternetAddress> list = new ArrayList<InternetAddress>();
		for (int i = 0; i < mailto.length; i++) {
			list.add(new InternetAddress(mailto[i]));
		}
		InternetAddress[] address = list.toArray(new InternetAddress[list.size()]);
		mimeMessage.setRecipients(Message.RecipientType.TO, address);
		mimeMessage = messageHelper.getMimeMessage();

		EmailThread et = new EmailThread(mimeMessage);
		et.start();
	}

	@Override
	public void sendBatchMailWithFile(String[] mailto, String fromEmail, String text, String title, String[] filePath) throws Exception {

		MimeMessage mimeMessage = javaMailSender.createMimeMessage();
		MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
		messageHelper.setFrom(new InternetAddress(MimeUtility.encodeText(fromEmail)));
		messageHelper.setSubject(title);
		if (filePath != null) {
			BodyPart mdp = new MimeBodyPart();// 新建一个存放信件内容的BodyPart对象
			mdp.setContent(text, "text/html;charset=UTF-8");// 给BodyPart对象设置内容和格式/编码方式
			Multipart mm = new MimeMultipart();// 新建一个MimeMultipart对象用来存放BodyPart对象
			mm.addBodyPart(mdp);// 将BodyPart加入到MimeMultipart对象中(可以加入多个BodyPart)
			// 把mm作为消息对象的内容
			MimeBodyPart filePart;
			FileDataSource filedatasource;
			// 逐个加入附件
			for (int j = 0; j < filePath.length; j++) {
				filePart = new MimeBodyPart();
				filedatasource = new FileDataSource(filePath[j]);
				filePart.setDataHandler(new DataHandler(filedatasource));
				try {
					filePart.setFileName(MimeUtility.encodeText(filedatasource.getName()));
				} catch (Exception e) {
					e.printStackTrace();
				}
				mm.addBodyPart(filePart);
			}
			mimeMessage.setContent(mm);
		} else {
			messageHelper.setText(text, true);
		}

		List<InternetAddress> list = new ArrayList<InternetAddress>();
		for (int i = 0; i < mailto.length; i++) {
			list.add(new InternetAddress(mailto[i]));
		}
		InternetAddress[] address = list.toArray(new InternetAddress[list.size()]);

		mimeMessage.setRecipients(Message.RecipientType.TO, address);
		mimeMessage = messageHelper.getMimeMessage();

		EmailThread et = new EmailThread(mimeMessage);
		et.start();
	}
}

3、服务配置


<bean name="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host" value="smtp.163.com" />
		<property name="defaultEncoding" value="UTF-8"></property>
		<property name="username" value="username@163.com"></property>
		<property name="password" value="password"></property>
		<property name="javaMailProperties">
			<map>
				<entry key="mail.smtp.auth" value="true" />
			</map>
		</property>		
	</bean>
