To integrate MyBatis in Spring Boot, you can follow these steps:

Add dependencies: Add dependencies for MyBatis and MyBatis-Spring in the `pom.xml` file. For example:

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.2.0</version>
</dependency>

2. Configure data source: Set up database connection information in `application.properties` or `application.yml`, for example:

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=username
spring.datasource.password=password

3. Create entity classes: Develop entity classes for corresponding database tables, mapping properties and database fields using annotations or XML.

4. Create a Mapper interface: define a Mapper interface related to database operations, and mark the interface with the `@Mapper` annotation.

Write SQL mapping files: Create a ‘mapper’ folder in the resources directory and write SQL mapping files to bind the methods in the Mapper interface to specific SQL statements.

6. Registering Mapper interface: Add the `@MapperScan` annotation on the main class of the application, specifying the package where the Mapper interface is located.

@SpringBootApplication
@MapperScan("com.example.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Using MyBatis: inject the Mapper interface using @Autowired where database access is needed, then you can perform database operations by invoking methods of the Mapper interface.

By following these steps, you have successfully integrated MyBatis into Spring Boot and can now use it to perform database operations. Make sure to correctly configure and use it according to the aforementioned steps to ensure smooth integration and operation.
