测试及使用

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class EmailTest {
    //注入邮件对象
    @Autowired
    JavaMailSenderImpl emailSender;
    
	//设置发送人账号
    @Value("${email.username}")
    private String  username;

    //简单邮件
    @Test
    public void testEmail() throws Exception{
        //得到信息对象
        SimpleMailMessage smm = new SimpleMailMessage();
        //发件人
        smm.setFrom(username);
        //收件人
        smm.setTo("");
        //发送标题
        smm.setSubject("恭喜你获得大奖");
        //发送信息
        smm.setText("中了全世界");
        emailSender.send(smm);
    }
    /*html邮件*/
    @Test
    public void testHtml() throws Exception{
        //html信息
        String html="<h1><font color='red'>恭喜你中大奖了</font></h1>";
        MimeMessage mm = emailSender.createMimeMessage();
        MimeMessageHelper mmh = new MimeMessageHelper(mm, true);
        //发件人
        mmh.setFrom(username);
        //收件人
        mmh.setTo("");
        //发送标题
        mmh.setSubject("恭喜你再中大奖");
        //发送内容
        mmh.setText(html, true);
        emailSender.send(mm);
    }
