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'


说明：
com.god.emo.app.service.impl.SysUserServiceImpl中构造函数的参数0需要类型为“com.god.demo.app.dao.mapper.SysUserMapper”的bean，但找不到该bean。
操作：
考虑在配置中定义一个类型为“com.god.demo.app.dao.mapper.SysUserMapper”的bean。
已断开与目标VM的连接，地址：“127.0.0.1:63159”，传输：“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);
    }

}
