Steps to integrate Spring Boot with MyBatis.

The steps to integrate Spring Boot and MyBatis are as follows:

1. Create a Spring Boot project: Generate a Maven project using Spring Initializr and include essential dependencies such as Spring Boot, MyBatis, and the database driver.
2. Set up the database connection: Configure the database connection information, including the database URL, username, and password, in the application.properties or application.yml file.
3. Create entity class: design the entity class corresponding to the database table, and use annotations in the entity class to map table names and field names to class properties.
4. Create a Mapper interface: Define a interface and its methods for database operations, annotate the interface with @Mapper to mark it as a MyBatis Mapper interface.
5. Create a Mapper.xml file: Create a Mapper.xml file corresponding to the Mapper interface in the resources directory, which will be used for writing SQL statements and mapping configurations.
6. Set the scanning path: Use the @MapperScan annotation on the startup class to specify the package path where the Mapper interfaces are located, enabling Spring Boot to scan and create instances of the Mapper interfaces.
7. Write business logic: Create business logic code in the Service layer, and call methods in the Mapper interface to perform database operations.
8. Write a Controller: Create interface methods in the Controller layer to call methods in the Service layer to process requests and return results.
9. 运行测试：运行项目，测试接口的正确性和数据库操作的准确性。

It is important to note that other configurations and optimizations can also be made based on specific requirements, such as using connection pooling, configuring transaction management, or utilizing MyBatis annotations, among others. The above is a basic integration process that can be adjusted and expanded as needed for the project.
