调用：

package mail;

public class Send {

 /**
  * @param args
  */
 public static void main(String[] args) {
     //这个类主要是设置邮件  
        MailSenderInfo mailInfo = new MailSenderInfo();   
        mailInfo.setMailServerHost("smtp.163.com");   
       mailInfo.setMailServerPort("25");   
        mailInfo.setValidate(true);   
        mailInfo.setUserName("[email protected]");   
        mailInfo.setPassword("itlm-0725");//您的邮箱密码   
        mailInfo.setFromAddress("[email protected]");   
        mailInfo.setToAddress("[email protected]");   
        mailInfo.setSubject("华科世家邮箱验证码");   
        mailInfo.setContent("123436");   
           //这个类主要来发送邮件  
        SimpleMailSender sms = new SimpleMailSender();  
            sms.sendTextMail(mailInfo);//发送文体格式   
            sms.sendHtmlMail(mailInfo);//发送html格式  

 }
