代码示例如下：

package com.JavaMail;

import java.io.UnsupportedEncodingException;
import java.util.Properties;

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

import org.apache.log4j.Logger;

public class MailServices {
	Logger log = Logger.getLogger(MailServices.class.getName());

	public void sendMail(String mailTitle, String receiveAddress,
			String sendAddress, String userName, String password,
			String serverSMTP) {
		String title = mailTitle;
		String serverSmtp = serverSMTP;// 10.3.7.10
		try {
			title = new String(title.getBytes("GBK"));
		} catch (UnsupportedEncodingException e) {
			log.error("邮件发送时出现异常", e);
		}
		Properties props = new Properties();
		props.put("mail.smtp.host", serverSmtp);
		props.put("mail.smtp.auth", "true");//不输出debug信息

		Session mailSession = Session.getDefaultInstance(props);
		mailSession.setDebug(true);//是否在控制台显示debug信息
		Message message = new MimeMessage(mailSession);
		try {
			message.setFrom(new InternetAddress(sendAddress));//发件人
			message.addRecipient(Message.RecipientType.TO, new InternetAddress(
					receiveAddress));// 收件人guo.yj@cppims.com
			message.setSubject(title);//设置标题
			message.setText(title);//邮件内容
			message.saveChanges();
		} catch (AddressException e) {
			log.error("邮件地址配置有误！", e);
		} catch (MessagingException e) {
			log.error("邮件配置时出现异常！", e);
		}
		try {
			Transport transport = mailSession.getTransport("smtp");
			transport.connect(serverSmtp, userName, password);
			transport.sendMessage(message, message.getAllRecipients());
			transport.close();
			log.info("邮件发送成功！");
		} catch (NoSuchProviderException e) {
			log.error("邮件发送时出现异常！", e);
		} catch (MessagingException e) {
			log.error("邮件发送时出现异常！", e);
		}
