> ### 一、问题描述 ###
> 
>     Description:
>     
>     Parameter 0 of constructor in com.god.demo.app.service.impl.SysUserServiceImpl required a bean of type 'com.god.demo.app.dao.mapper.SysUserMapper' that could not be found.
>     
>     
>     Action:
>     
>     Consider defining a bean of type 'com.god.demo.app.dao.mapper.SysUserMapper' in your configuration.
>     
>     Disconnected from the target VM, address: '127.0.0.1:63159', transport: 'socket'
> 
> ### **二、创建文件MyBatisConfig** ###
> 
>     @MapperScan("com.xx.dao.mapper")
>     @Configuration
>     public class MyBatisConfig {
>     
>         @Bean
>         public ConfigurationCustomizer configurationCustomizer() {
>             return configuration -> {
>                 //驼峰命名法
>                 configuration.setMapUnderscoreToCamelCase(true);
>             };
>         }
>     }
> 
> ### 三、或者直接 ###
> 
>     @MapperScan("com.xx.dao.mapper")
>     @SpringBootApplication
>     public class DemoApplication {
>     
>         public static void main(String[] args) {
>             SpringApplication.run(DemoApplication.class, args);
>         }
>     
>     }
