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(
"dengjianli@126.com", 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：masterspring2@gmail.com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masterspring2@gmail.com是可以发送的。
用到jar包：
