方法一:

　　　　java发送电子邮件:这里以发送qq邮件为例:

　　　　package test;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.BodyPart;
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.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class MySendEmail {
   public static void main(String[] args) {
       try {
           String userName = "发送方qq号@qq.com";
           String password = "发送方邮箱密码";
           String smtp_server = "smtp.qq.com"; //qq邮箱邮件服务器地址
           String from_mail_address = userName;
           String to_mail_address = "接收方qq号@qq.com";
           Authenticator auth = new PopupAuthenticator(userName, password);
           Properties mailProps = new Properties();
           mailProps.put("mail.smtp.host", smtp_server);
           mailProps.put("mail.smtp.auth", "true");
           mailProps.put("username", userName);
           mailProps.put("password", password);

           Session mailSession = Session.getDefaultInstance(mailProps, auth);
           mailSession.setDebug(true);
           MimeMessage message = new MimeMessage(mailSession);
           message.setFrom(new InternetAddress(from_mail_address));
           message.setRecipient(Message.RecipientType.TO, new InternetAddress(
                   to_mail_address));
           message.setSubject("Mail Testw");

           MimeMultipart multi = new MimeMultipart();
           BodyPart textBodyPart = new MimeBodyPart();
           textBodyPart.setText("Java电子邮件测试内容w");
           // textBodyPart.setFileName("37af4739a11fc9d6b311c712.jpg");
           textBodyPart.setFileName("E:\\API\\W3C.chm");

           multi.addBodyPart(textBodyPart);
           message.setContent(multi);
           message.saveChanges();
           Transport.send(message);
       } catch (Exception ex) {
           System.err.println("邮件发送失败的原因是：" + ex.getMessage());
           System.err.println("具体的错误原因");
           ex.printStackTrace(System.err);
       }
   }
}

class PopupAuthenticator extends Authenticator {
   private String username;
   private String password;

   public PopupAuthenticator(String username, String pwd) {
       this.username = username;
       this.password = pwd;
   }

   public PasswordAuthentication getPasswordAuthentication() {
       return new PasswordAuthentication(this.username, this.password);
   }

方法二: 用Spring提供的发邮件功能,同样以发送qq邮箱为例:

　　beans.xml文件代码:

<?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:aop="http://www.springframework.org/schema/aop"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
   
   <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
       <property name="host">
           <value>smtp.qq.com</value>
       </property>
       <property name="javaMailProperties">
           <props>
               <prop key="mail.smtp.auth">true</prop>
               <prop key="mail.smtp.timeout">25000</prop>
           </props>
       </property>
       <property name="username">
           <value>发送方qq号@qq.com</value>
       </property>
       <property name="password">
           <value>发送方qq邮箱密码</value>
       </property>

   </bean>
</beans>

发送邮件的Java代码：

package test;

import java.util.UUID;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

public class SendMail {

   public ApplicationContext ctx = null;
   public SendMail() {
      //获取上下文
      ctx = new ClassPathXmlApplicationContext("beans.xml");
   }
   public void send() {
      //获取JavaMailSender bean
      JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
      SimpleMailMessage mail = new SimpleMailMessage(); //<SPAN style="COLOR: #ff0000">注意SimpleMailMessage只能用来发送text格式的邮件</SPAN>


      try {
       mail.setTo("接收者@qq.com");//接受者
       mail.setFrom("发送者@qq.com");//发送者,这里还可以另起Email别名，不用和xml里的username一致
       mail.setSubject("spring mail test!");//主题
       mail.setText("springMail的简单发送测试,附带随机验证码为:"+UUID.randomUUID().toString().substring(0, 6));//邮件内容

       sender.send(mail);
      } catch (Exception e) {
       e.printStackTrace();
      }
   }

   public static void main(String[] args) {
       for(int i=0;i<100;i++){

           SendMail sendMail = new SendMail();
           sendMail.send();
           System.out.println("发送完毕...");

       }

   }
}
