有两种方法可以实现这一点。模型监听器方式有点棘手，因为在调用模型监听器之后，文章和类别之间的关联就建立起来了。id已经被分配（article.getId（）），但是需要一些技巧来克服这个问题。

直接的方法是创建一个服务包装器，调用原始代码，然后使用服务上下文来确定进一步的操作。

考虑通过在LIFELYE消息总线上使用异步消息来将发送邮件的代码解耦。

如果您在Liferay中配置了SMTP服务器，您还可以使用MailService从门户发送电子邮件。

查看示例代码

@Component(immediate = true, property = {}, service = 
ServiceWrapper.class)
public class MailServiceWrapper extends JournalArticleServiceWrapper {

  private static final Log _log = LogFactoryUtil.getLog(MailServiceWrapper.class);

  private  MailService mailService;
