What is the function of MyBatis interceptors?

The role of MyBatis interceptors is to intercept and process SQL statements during execution. Interceptors can perform custom operations before and after SQL statement execution, such as logging, performance monitoring, and permission control.

Specifically, interceptors can modify SQL statements before execution, such as adding additional conditions or changing sorting methods; they can also process the results after SQL execution, such as further processing query results or handling auto-increment primary keys returned from insertion operations.

By using custom interceptors, we can conveniently intervene and extend SQL statements to meet specific requirements, improving the performance and security of the system.
