What are the functions of MyBatis?

MyBatis serves several purposes, including the following:

1. Simplified the development of the data access layer: MyBatis offers the ability to automatically map and perform CRUD operations, making it easier to write code for the data access layer. Developers only need to write SQL statements to perform database operations.
2. MyBatis provides a flexible way to write SQL: allowing developers to use native SQL statements to write complex queries to meet various needs.
3. Support for dynamic SQL: MyBatis offers the functionality of dynamic SQL, allowing for the generation of different SQL statements based on different conditions, improving the reusability and flexibility of SQL statements.
4. Providing a caching mechanism: MyBatis supports both first-level and second-level caching, which can reduce the number of database accesses and enhance system performance.
5. Support for plugin extensions: MyBatis offers a plugin mechanism, which allows for easy extension of MyBatis by customizing certain features or modifying its default behavior.

Overall, the purpose of MyBatis is to simplify the development of the data access layer by providing a flexible way to write SQL, supporting dynamic SQL and caching mechanisms, as well as offering the ability to extend functionality with plugins, making it easier for developers to interact with databases.
