java实现基于SMTP发送邮件的方法

本文实例讲述了java实现基于smtp发送邮件的方法。分享给大家供大家参考。具体实现方法如下：

import java.util.date;
import java.util.properties;
import javax.mail.authenticator;
import javax.mail.message;
import javax.mail.passwordauthentication;
import javax.mail.session;
import javax.mail.transport;
import javax.mail.internet.internetaddress;
import javax.mail.internet.mimemessage;
import org.apache.log4j.logger;
public class mailutil {
 private static logger logger = logger.getlogger(mailutil.class);
 /**
  * 发送邮件
  * 
  * @param smtp
  *   smtp服务器
  * @param user
  *   用户名
  * @param password
  *   密码
  * @param subject
  *   标题
  * @param content
  *   邮件内容
  * @param from
  *   发件人邮箱
  * @param to
  *   收件人邮箱
  */
 public static void send(string smtp, final string user,
   final string password, string subject, string content, string from,
   string to) {
  try {
   properties props = new properties();
   props.put("mail.smtp.host", smtp);
   props.put("mail.smtp.auth", "true");
   session ssn = session.getinstance(props, new authenticator() {
    @override
    protected passwordauthentication getpasswordauthentication() {
     return new passwordauthentication(user, password);
    }
   });
   mimemessage message = new mimemessage(ssn);
   //由邮件会话新建一个消息对象 
   internetaddress fromaddress = new internetaddress(from);
   //发件人的邮件地址 
   message.setfrom(fromaddress);
   //设置发件人 
   internetaddress toaddress = new internetaddress(to);
   //收件人的邮件地址 
   message.addrecipient(message.recipienttype.to, toaddress);
   //设置收件人
   message.setsubject(subject);
   //设置标题
   message.settext(content);
   //设置内容
   message.setsentdate(new date());
   //设置发信时间 
   transport transport = ssn.gettransport("smtp");
   transport.connect(smtp, user, password);
   transport.sendmessage(message, message
     .getrecipients(message.recipienttype.to));
   // transport.send(message);
   transport.close();
   logger.info("邮件发送成功");
  } catch (exception e) {
   logger.warn("邮件发送失败", e);
  }
 }
}
