UserService.java

package text;


import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import javax.mail.MessagingException;

@Service
public class UserService {
   //@Resource
   // private JavaMailSender mailSender;//,mailSender找Spring_mvc.xml的id的
    @Resource
    private  MailSender mailSender;
    public void sendMailDemo() throws MessagingException {

       SimpleMailMessage mailMsg = new SimpleMailMessage();//只支持文字
        mailMsg.setFrom("8962@qq.com");//发件人
        mailMsg.setTo("11717@qq.com");//收件人
        mailMsg.setSubject("很棒哦，今晚你回去扫地了");//邮件标题
        mailMsg.setText("哦哦"); //测试内容
        mailSender.send(mailMsg);//发送*

    }
   @Test
    public void test() throws MessagingException {
    ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("Spring_mvc.xml");
      mailSender = (MailSender) ctx.getBean("mailSender");



        };
    }

 

这样就可以简单的发文字邮件了！！！
