Caused by: com.mysql.cj.exceptions.CJCommunicationsException: Communications link failure

Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

归档统计时并没有对已删除博客做一个筛选(已提PR)

• 状态为0的博客依然会被统计进去

亦或是说归档统计本就是统计包括已删除的所有博客？(如果是这样，请无视🤣，然而，删除博客后依然会对Redis的归档信息做一个删除，显得有些多余了)

源码位置

最初看到此处代码，内心的感觉是一个字“妙”，不过想来想去还是感觉不对劲。

问题就是——怀疑它是否有存在的必要性：

项目中并没有禁止Session（猜测与此有关），但前后端分离后axios默认会丢失session_id，那么最后的结果依然是每条请求都是需要验证的（前端项目是否已经主动携带还没有看）。

即便如此，此处的判断存在于 查询到request中包含了 正确 jwt_token 的情况下，如果请求不携带token 那么也会被视作游客，Session好像全程都并没有参与进来。

配置类中给出的 JWT 参考过期时间为5天，可以理解的方向就是用jwt代替session。那么是否应该禁用session并删除此处的判断呢？

我在进行用户注册时报 邮箱验证码不正确 的错误

发现是 redis存储key value的问题

redis存储的code值(验证码) 相比 邮箱发送 的多了一个邮箱发送状态
例如邮箱发送code值(验证码)为854570
而此时Redis存入的值为854570_1(1表示邮箱发送成功)
当用户注册的时候，后台通过Redis查出的Key值进行对比会返回错误

Direct use of "${}" in Mapper files will bring the risk of SQL injection.

Databases are vulnerable to SQL injection attacks.

我认为这个项目对于Java入门者来说依然是个很好的项目：

• 使用了Spring的AOP进行日志的拦截
• 使用了MVC映射本地静态资源实现图片访问
• 对于Redis和数据库的数据一致性和消息队列的使用也很值得深究
• Security+JWT+Redis的认证方式学习到很多东西
• 前端的使用也并不繁杂，对于有前端基础的Java入门者来说依然能做一些自定义样式修改
• 深入考虑也能思考单机下的并发控制（使用JUC或synchronized

我能否为该项目写一份简单的功能模块说明文档呢🤣

单页面单博客，怎么对文章进行seo优化

请问在com.zzx.service.BlogService的

public List<Blog> findHomeBlog(Integer page, Integer showCount)

方法里，设置缓存的部分，有三个分支，也就是①不在缓存，②部分在缓存，③全部在缓存。
通过读您的代码可以了解到，tag标签是通过tagDao来根据博客id来获取到并设置到blog对象的。
在第①个情况，不在缓存时，是通过blogDao获取到博文数据后再通过tagDao来设置博文标签的。
但是在第②个情况里，也就是部分在缓存的情况中，在查询MySQL后的结果中是没有看见有使用到tagDao来设置博文标签的，请问这个是否是一个bug，或是别的地方有所设置。

Direct use of "${}" in Mapper files will bring the risk of SQL injection.
We can use boolean blind injection to attack the database.

我在docker配置好其他服务后，在本地启动前、后端项目后，前端页面如图

查看后端log日志，发现如下

我想询问一下这个问题该怎么解决呢？
