项目启动报错 ``` Unsatisfied dependency expressed through field 'baseMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: ``` 我这里的原因是 模块加了一层目录, 没有修改 MapperScan 扫描地址, 导致找不到mapper 层了 解决 ``` 启动类的 @MapperScan 地址配置错误了 @MapperScan(basePackages = "com.toker.*.mapper") ```
