测试代码

package com.carlos;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.messaging.MessagingException;

public class SingleMailSend {

    
    
     
    public static void main(String args[]) throws MessagingException {
        ApplicationContext actx = new ClassPathXmlApplicationContext(
                "applicationContext.xml");
        SimpleMailMessage mailMessage = (SimpleMailMessage) actx.getBean("mailMessage");
        MailSender sender = (MailSender) actx.getBean("mailSender");
        mailMessage.setSubject("你好");
        mailMessage.setText("这个是一个通过Spring框架来发送邮件的小程序");
        mailMessage.setTo("473/996/@qq.com");
        sender.send(mailMessage);
        
    }
}
