This is a simple user management system implemented using Spring Boot, MyBatis, and MySQL. The project includes features for creating, updating, deleting, and retrieving user information.
This is the main class of the Spring Boot application that contains the main method. It starts the Spring Boot application by calling the SpringApplication.run method. The @SpringBootApplication annotation enables auto-configuration, component scanning, and Spring Bean initialization.
The controller class for user management. It defines methods for adding, deleting, updating, and retrieving users by invoking the corresponding operations in the UserService.
This is the service interface that defines business operations related to user management. The methods in this interface are implemented by the UserServiceImpl class.

The data access object (DAO) responsible for interacting with the database. It uses methods defined in the UserMapper interface with MyBatis annotations to execute SQL operations.
The MyBatis mapper interface where SQL queries for user management are defined using annotations. Each method corresponds to a SQL statement for inserting, deleting, updating, or querying user information.
The user model class that defines the properties of a user (e.g., ID, username, gender, age, etc.). It also includes the necessary getter, setter, and other basic methods.
The configuration file for the Spring Boot application. It contains database connection settings and MyBatis configurations.
The Maven configuration file that defines the project dependencies and build plugins. Key dependencies include Spring Boot, MyBatis, MySQL Connector, JUnit 5, and Mockito for testing.
The following SQL script is used to create and configure the database table. It has already been imported into the local environment:
CREATE DATABASE db1; USE db1; CREATE TABLE users ( id BIGINT AUTO_INCREMENT PRIMARY KEY COMMENT 'Primary Key', username VARCHAR(50) NOT NULL COMMENT 'Username', gender TINYINT(1) NOT NULL COMMENT 'Gender', age INT NOT NULL COMMENT 'Age', create_user VARCHAR(40) NOT NULL COMMENT 'Creator Identifier', create_user_name VARCHAR(128) NOT NULL COMMENT 'Creator Name', create_time DATETIME NOT NULL COMMENT 'Creation Time', update_user VARCHAR(40) NOT NULL COMMENT 'Last Updater Identifier', update_user_name VARCHAR(128) NOT NULL COMMENT 'Last Updater Name', update_time DATETIME NOT NULL COMMENT 'Last Update Time', is_delete TINYINT(1) DEFAULT 0 NOT NULL COMMENT 'Delete Flag: 0 - Not Deleted, 1 - Deleted' );
