To import the MyBatis configuration file in Spring Boot, you need to complete the following steps: 1. Create a configuration file named `mybatis-config.xml` in the `src/main/resources` directory. In this file, you can configure some global parameters and plugins for MyBatis. 2. Add the MyBatis configuration properties in `application.properties` or `application.yml`. You can refer to the following example:

  # MyBatis配置文件的位置
   mybatis.config-location=classpath:mybatis-config.xml
   
   # MyBatis mapper接口所在的包路径
   mybatis.mapper-locations=classpath:mapper/*.xml
  mybatis:
     config-location: classpath:mybatis-config.xml
     mapper-locations: classpath:mapper/*.xml

In the above configuration, `mybatis.config-location` specifies the location of the MyBatis configuration file, and `mybatis.mapper-locations` specifies the path of the XML file where Mapper interfaces are located. To specify the package path where Mapper interfaces are located, add the `@MapperScan` annotation to the Spring Boot startup class. Example:

  import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.mybatis.spring.annotation.MapperScan;
   
   @SpringBootApplication
   @MapperScan("com.example.mapper")
   public class Application {
       public static void main(String[] args) {
           SpringApplication.run(Application.class, args);
       }
   }

In the above code, `@MapperScan` specifies the package path where the Mapper interfaces are located, allowing Spring Boot to automatically scan and register these Mapper interfaces. Once this step is completed, the configuration file and Mapper interfaces of MyBatis will be correctly loaded and utilized.
