您可以为电子邮件通知编写自定义工作流程过程。在该类中，您可以从工作流实例模型中读取工作流启动器。此数据保存在userid属性中的元数据节点下。

@Service
@Component(immediate = true)
public final class NotificationWorkflowProcess implements WorkflowProcess {

    @Reference
    private MessageGatewayService messageService;

    @Override
    public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaDataMap) throws WorkflowException {
        ResourceResolver resolver = workflowSession.adaptTo(ResourceResolver.class); // or get admin resolver here
        UserManager userManager = resolver.adaptTo(UserManager.class);

        MessageGateway<HtmlEmail> messageGateway = messageService.getGateway(HtmlEmail.class);
        try {
            String initiator = workItem.getWorkflow().getInitiator();
            Authorizable authorizable = userManager.getAuthorizable(initiator);
            String userEmail = PropertiesUtil.toString(authorizable.getProperty("profile/email"), "");
            if(StringUtils.isBlank(userEmail)) {
                return;
            }
            HtmlEmail email = new HtmlEmail();
            email.setCharset(CharEncoding.UTF_8);
            email.addTo(userEmail);
            email.setSubject("test email subject");
            email.setMsg("text email body");
            email.setHtmlMsg("<!DOCTYPE html><html><head></head><body><p>html email body</p></body></html>");
            messageGateway.send(email);
        } catch(Exception e) {
            // cannot send email. print some error
            e.printStackTrace();
        }
    }
}
