        simpleMailMessage.setText("123456");
        //发送
        javaMailSender.send(simpleMailMessage);
    }
    @Test
    public void testHtmlSend() throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        //声明simplemailMessage
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
        //发送者
        mimeMessageHelper.setFrom(from);
        //接收者
        mimeMessageHelper.setTo("*******@qq.com");
        //内容主体
        StringBuffer stringBuffer = new StringBuffer();
        stringBuffer.append("这是html邮件");
        mimeMessageHelper.setText(stringBuffer.toString(),true);
        //主题
        mimeMessageHelper.setSubject("测试");
        //发送
        javaMailSender.send(mimeMessage);
    }
    @Test
    public void testFileSend() throws MessagingException {
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        //声明simplemailMessage
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
        //发送者
        mimeMessageHelper.setFrom(from);
        //接收者
        mimeMessageHelper.setTo("*****@qq.com");
        //内容主体
        StringBuffer stringBuffer = new StringBuffer();
        stringBuffer.append("这是html邮件");
        mimeMessageHelper.setText(stringBuffer.toString(),true);
        //放置附件
        FileSystemResource fileSystemResource = new FileSystemResource(new File("E://1.jpg"));
        mimeMessageHelper.addAttachment("lxl.jpg",fileSystemResource);
        //主题
        mimeMessageHelper.setSubject("测试");
        //发送
        javaMailSender.send(mimeMessage);
    }
