how i can write junit for this mail code with template, here i am sending mail with template this is my Service class Method:我如何用模板为这个邮件代码写 junit,这里我用模板发送邮件这是我的服务 class 方法:
@Service
public class ServiceImpl {
@Autowired
private JavaMailSender javaMailSender;
@Autowired
private Configuration configuration;
@Value("${mail.send.to}")
private String mailSendTo;
public void sendMailOnEmailOptOut()
throws MessagingException, IOException, TemplateException {
String[] toAddressList = { mailSendTo };
final String emailSubject = "email opt out testing";
MimeMessage message = javaMailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message,
MimeMessageHelper.MULTIPART_MODE_MIXED_RELATED,
StandardCharsets.UTF_8.name());
helper.setTo(toAddressList);
StringWriter stringWriter = new StringWriter();
Map<String, Object> model = new HashMap<>();
model.put("user", "this is just for testing");
configuration.getTemplate("email.template.html").process(model, stringWriter);
String emailContent = stringWriter.getBuffer().toString();
helper.setText(emailContent, true);
helper.setSubject(emailSubject);
javaMailSender.send(message);
}
mail_send_to value come from property file and this is email.template.html is in src->main->resources template folder mail_send_to 值来自属性文件,这是 email.template.html 在 src->main->resources 模板文件夹中
<!doctype html>
