配置文件增加mybatis配置

application.yml

mybatis:
  mapper-locations: classpath:/mapper/**/*.xml

入口文件配置

@SpringBootApplication
@MapperScan("com.kinda.springBootDemo.mapper") // mapper包位置
@RestController
public class SpringBootDemoApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext configurableApplicationContext = SpringApplication.run(SpringBootDemoApplication.class, args);
        String[] beans = configurableApplicationContext.getBeanDefinitionNames();
    }
