Springboot + mybatis-plus 报错 java.nio.file.AccessDeniedException

记录一次 java.nio.file.AccessDeniedException的解决

先看我的报错信息

Caused by: java.nio.file.AccessDeniedException: D:\WorkSpace\Java_IDEA_workspace\jxj\target\classes\com\hdu\jxj\project\background\abroad\mapper

报的错误很明确，提示说无法到达’‘D:\WorkSpace\Java_IDEA_workspace\jxj\target\classes\com\hdu\jxj\project\background\abroad\mapper’'这个目录。

所以开始思考我这个目录配置的地方在哪，想到我的目录其实配置在application.yml中，所以打开该文件发现

这里简单介绍下springboot中通配符的用法：

• ？：匹配一个字符
• *：匹配多个字符
• **：匹配多级目录

所以此处的通配符应该使用 *

之后项目启动成功！
