//还是这个BeanCreationException,究竟是什么原因呢？
//还想问一下老师，老师您给的pom.xml文件是不是不全，我跟着您的步骤做的，发现如LoadingCache，
//@JsonIgnore等需要自己再去加一些maven依赖，而且我把<org.mybatis.version>的版本改为了更早
//之前的，要不然就无法使用@param的这个注解，想知道具体的一点原因，谢谢老师！

Geely

我给的pom文件是全的~~而且版本也是对的，同学是在哪里下的源码。。课程源码可以直接run起来的，配置好环境。你的这个异常，还需要看一下application-datasource配置文件，把这个也发上来，看看读取properties文件这块是咋回事。

你好，同学，我看这个关键异常

可以把db相关的配置发上来，例如这个 is java.lang.NumberFormatException: For input string: "${db.initialSize}";

格式错误，看看你的格式是不是错误了？有些引号么？发上来具体的配置，我们一起看看。
