版本一：JavaMail的一个工具类

package ${enclosing_package};

import java.security.GeneralSecurityException;
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.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;

import com.sun.mail.util.MailSSLSocketFactory;

public class ${primary_type_name} {

    //email:邮件发给谁  subject:主题  emailMsg：邮件的内容
    public static void sendMail(String email, String subject, String emailMsg)
            throws AddressException, MessagingException {

        // 1.创建一个程序与邮件服务器会话对象 Session
        Properties props = new Properties();
        props.setProperty("mail.transport.protocol", "SMTP");//发邮件的协议
        props.setProperty("mail.host", "smtp.126.com");//发送邮件的服务器地址
        props.setProperty("mail.smtp.auth", "true");// 指定验证为true

        //开启SSL加密  ,QQ邮箱必须开启ssl加密才可以。
        MailSSLSocketFactory sf = null;
        try {
            sf = new MailSSLSocketFactory();
        } catch (GeneralSecurityException e) {

            e.printStackTrace();
        }
        sf.setTrustAllHosts(true);
        props.put("mail.smtp.ssl.enable", "true");
        props.put("mail.smtp.ssl.socketFactory", sf);

        // 创建验证器
        Authenticator auth = new Authenticator() {
            public PasswordAuthentication getPasswordAuthentication() {
                //发邮件的账号的验证 12345为授权码，并非密码。tom可以不用加上@126.com
                return new PasswordAuthentication("tom", "12345");
            }
        };

        //这个是邮箱服务器的session 和之前学的session不是同一个session
        Session session = Session.getInstance(props, auth);

        // 2.创建一个Message，它相当于是邮件内容
        Message message = new MimeMessage(session);

        message.setFrom(new InternetAddress("tom@126.com")); // 设置发送者

        message.setRecipient(RecipientType.TO, new InternetAddress(email)); // 设置发送方式与接收者

        message.setSubject(subject);//邮件的主题

        message.setContent(emailMsg, "text/html;charset=utf-8");

        // 3.创建 Transport用于将邮件发送
        Transport.send(message);
    }
}

 一个JavaMail的例子

package com.test.jobs;

import java.security.GeneralSecurityException;
import java.util.List;

                    Transport.send(message);
                }
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}

spring的注入方式如下：

<bean name="myJob" class="com.test.jobs.MailJob">
    <property name="username" value="tom@126.com"/>
    <property name="password" value="123456"/>
    <property name="smtpServer" value="smtp.126.com"/>
    <property name="protocol" value="SMTP"/>
</bean>
