java 发送邮件

利用 javamail 发送邮件，需要用到activation.jar和mail.jar

需注意邮件服务器的配置，不清楚的可以google

package com.nfschina.mail;import java.io.UnsupportedEncodingException;import java.util.Calendar;import java.util.Date;import java.util.Properties;import javax.mail.Address;import javax.mail.Authenticator;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.PasswordAuthentication;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;class PopupAuthenticator extends Authenticator {public static final String mailuser = "[e-mail]";public static final String password = "815676007";public PasswordAuthentication getPasswordAuthentication() {return new PasswordAuthentication(mailuser, password);}}public class MailTest {public static void main(String args[]) throws MessagingException,UnsupportedEncodingException {Properties props = new Properties();props.put("mail.transport.protocol", "smtp");props.put("mail.smtp.port", String.valueOf(25));props.put("mail.smtp.host", "smtp.nfschina.com");props.put("mail.smtp.auth", "true");props.put("mail.smtp.connectiontimeout", 25 * 1000);PopupAuthenticator auth = new PopupAuthenticator();Session session = Session.getInstance(props, auth);session.setDebug(true);MimeMessage message = new MimeMessage(session);Address addressFrom = new InternetAddress("[e-mail]","high");Address addressTo = new InternetAddress("[e-mail]", "high");message.setContent("邮件发送成功", "text/html;charset=GBK");// message.setText("邮件发送成功");Calendar c = Calendar.getInstance();c.set(2010, 9, 19, 10, 0);Date d = new Date();d.setTime(c.getTimeInMillis());// message.setSentDate(d);message.setSubject("Javamal测试发送邮件");message.setFrom(addressFrom);message.addRecipient(Message.RecipientType.TO, addressTo);message.saveChanges();Transport transport = session.getTransport("smtp");System.out.println(PopupAuthenticator.mailuser);System.out.println(PopupAuthenticator.password);transport.connect("smtp.nfschina.com", 25, PopupAuthenticator.mailuser,PopupAuthenticator.password);Transport.send(message);transport.close();}}

 

 

   上面的邮件发送实例其实可以再简单一些，因为spring提供的org.springframework.mail.javamail.JavaMailSenderImpl

已经对java mail发送邮件进行了封装，使用起来极为简便。

 

applicationContext.xml配置如下

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xmlns:jee="http://www.springframework.org/schema/jee"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsdhttp://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"><bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"><property name="host" value="smtp.nfschina.com" /><property name="javaMailProperties"><props><prop key="mail.smtp.auth">true</prop><prop key="mail.smtp.timeout">25000</prop></props></property><property name="username" value="[e-mail]" /><property name="password" value="123456" /></bean></beans>
