利用JavaMail发送邮件

       这次项目里有流程审批操作，涉及到的工作流里流程控制都是自己写的，其中发送通知有站内信、短信和邮件，发送邮件我选择了JavaMail，比较通用。引入一个核心jar即可（mail.jar），java代码如下：

import java.util.Properties;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;


public class MailSend {

	public static String host;//smtp服务器
	public static String user;//用户名，即发送邮件的邮箱
	public static String password;//密码
	public static String fromMailAddress;//发送人地址
	public static String from;//发送人要显示的名称
	
	protected Log logger = LogFactory.getLog(getClass());
	
	@SuppressWarnings("static-access")
	public MailSend(String host,String user,String password,String fromMailAddress,String from){
		this.host=host;
		this.user=user;
		this.password=password;
		this.fromMailAddress =fromMailAddress;
		this.from=from;
	}

	public void send(String[] toMailAddress, String subject,String content) {

		Properties props = new Properties();
		props.put("mail.smtp.host", host);// 指定SMTP服务器
		props.put("mail.smtp.auth", "true");// 指定是否需要SMTP验证
		try {
			Session mailSession = Session.getInstance(props);
			mailSession.setDebug(false);// 是否在控制台显示debug信息
			MimeMessage message = new MimeMessage(mailSession);
			
			String nick=javax.mail.internet.MimeUtility.encodeText (from, "utf-8", null);
			message.setFrom(new InternetAddress(nick+" <"+fromMailAddress+">"));

			InternetAddress[] sendTo = new InternetAddress[toMailAddress.length];
			for (int i = 0; i < toMailAddress.length; i++) {
				sendTo[i] = new InternetAddress(toMailAddress[i]);
			}
			message.setRecipients(
					javax.mail.internet.MimeMessage.RecipientType.BCC, sendTo);
			message.setSubject(subject, "utf-8");// 邮件主题
			message.setContent(content, "text/html;charset=utf-8");
			message.saveChanges();
			Transport transport = mailSession.getTransport("smtp");
			transport.connect(host,user,password);
			transport.sendMessage(message, message.getAllRecipients());
			transport.close();
		} catch (Exception e) {
			logger.info("send mail error:   "+e.toString());
			e.printStackTrace();
		}

	}
	
	public static boolean  isNameAdressFormat(String email){   
        	boolean isExist = false;   
        	Pattern p = Pattern.compile("(\\w[-._\\w]*\\w@\\w[-._\\w]*\\w\\.\\w{2,3})");   
        	Matcher m = p.matcher(email);   
        	boolean b = m.matches();   
        	if(b) {   
             		isExist=true;   
         	} else {   
             		System.out.println(email +" error email is :无效邮件地址----------");   
         	}   
        	return isExist;   
     }  
	
	public static void main(String[] args) {
		String rec[] =new String[2];
		rec[0]=("[email protected]");
		rec[1]=("[email protected]");
		MailSend ms=new MailSend("smtp.163.com","123456","abc123","[email protected]","hehe");
		ms.send(rec,"aaaaaaa","ddddddd");
