Spring 发送电子邮件

在学习spring之前先学习以下不用spring来实现javamail的邮件发送：

用到得jar包：

package com.css.service.email;

import java.security.Security;
import java.util.Date;
import java.util.Properties;

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.URLName;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class JavaMailSslSender {

 public static void main(String[] args) throws AddressException,
   MessagingException {
//  加密邮件有提供的类Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
  final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
  // Get a Properties object
  Properties props = System.getProperties();
  props.setProperty("mail.smtp.host", "smtp.gmail.com");服务主机地址
  props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
  props.setProperty("mail.smtp.socketFactory.fallback", "false");
  props.setProperty("mail.smtp.port", "465");端口
  props.setProperty("mail.smtp.socketFactory.port", "465");
  props.put("mail.smtp.auth", "true");是否要验证身份

//邮箱的用户名和密码
  final String username = "masterspring2";
  final String password = "spring";

验证用户名和密码
  Session session = Session.getDefaultInstance(props,
    new Authenticator() {
     protected PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication(username, password);
     }
    });
  Message msg = new MimeMessage(session);

发送邮件地址

  msg.setFrom(new InternetAddress(username + "@gmail.com"));
  接受邮件地址
  msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(
    "[e-mail]", false));
  msg.setSubject("Hello");
  msg.setText("How are you");
  msg.setSentDate(new Date());
  URLName urln = new URLName("smtps", "smtp.gmail.com", 465, null,"masterspring2", "spring");
        Transport t = session.getTransport(urln);
  t.send(msg);

  System.out.println("Message sent.");
 }
}

spring实现javamail：（用红色表注的请注意：需要改动的）

这里的发送邮件的服务器地址：[e-mail]是可以接受服务的smtp协议。你也可以自己申请了一个邮箱地址。但是好像126、163邮箱的2007年11份之后申请的邮箱都不能用smtp服务。这里用的邮箱地址[e-mail]是可以发送的。

用到jar包：
