//获取系统属性，主要用于设置邮件相关的参数。

Properties properties = System.getProperties();

properties.setProperty("mail.smtp.host", "smtp.xxx");//smtp协议地址

properties.setProperty("mail.smtp.port", "xx");//端口号

Session session = Session.getDefaultInstance(properties, new Authenticator() {

}

});

//创建MimeMessage消息对象，消息头配置了收发邮箱的地址，消息体包含了邮件标题和邮件内容。接收者类型：TO代表直接发送，CC代表抄送，BCC代表秘密抄送。

try {

MimeMessage message = new MimeMessage(session);

message.addHeader("X-Mailer","Microsoft Outlook Express 6.00.2900.2869");

message.setFrom(new InternetAddress(from));

message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

message.setSubject("标题");

message.setText("内容");

Transport.send(message);

System.out.println("发送成功！");

return "success";

} catch (MessagingException e) {

e.printStackTrace();

测试类：

public class MyTest {

public static void main(String[] args) {

ToExchangeMail mail=new ToExchangeMail();

mail.sendMain("接收人的邮箱");

}

}
