『博客开发日记』之发送评论会给个人发送邮箱通知功能

本文最后更新于 2026年2月8日 下午

发送评论会给个人发送邮箱通知功能

邮箱收取评论功能

当有人发评论或者回复评论时会通过邮箱通知别人

要根据评论者是在哪个地方发表的评论（文章内，友链区，留言板）来发送不同标题的邮箱

根据新评论还是回复别人的评论来发送邮箱，如果是回复的评论要显示回复的哪条评论

如果是博主自己发表的评论或者是自己回复自己的评论就不要发送邮箱给本人了

着其实和发邮箱验证码功能相似都是通过Spring Boot Mail 邮件服务来实现

现在EmailServiceImpl中添加sendCommentNotificationByEmail方法实现邮箱通知功能
