What is the difference between Hibernate and MyBatis?

Hibernate and MyBatis are both Java persistence frameworks, but they have some differences.

1. Hibernate is an ORM framework that directly maps Java objects to database tables, allowing developers to interact with the database in an object-oriented manner. On the other hand, MyBatis is a SQL mapping framework where developers need to manually write SQL statements to map SQL to Java code.
2. Object state management: Hibernate manages the state of objects through Session, which includes persistence, detachment, and deletion, without developers needing to manually handle the state of objects. In contrast, MyBatis does not have object state management functionality, so developers must manually manage the lifecycle of objects.
3. Performance: Due to Hibernate’s use of ORM technology, it may result in decreased performance due to the high number of object operations and queries. On the other hand, MyBatis directly utilizes SQL statements, allowing for more precise control over the execution logic of SQL, resulting in higher performance.
4. Flexibility: Hibernate offers better flexibility and automation when dealing with complex data structures and relationships, while MyBatis is more suitable for scenarios that require manual SQL statement writing and have a higher demand for native SQL.

In summary, Hibernate is suitable for object-oriented development and can easily handle basic CRUD operations with simple configuration, while MyBatis is better suited for situations where there is a need for more advanced SQL skills and higher performance requirements.
