mybatis springboot Example

Sure! Here's an example of using MyBatis with Spring Boot:

First, make sure you have the necessary dependencies in your `pom.xml` file:

<dependencies>
    <!-- other dependencies -->
    
    <!-- MyBatis -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.4</version>
    </dependency>
    
    <!-- MySQL Connector -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
</dependencies>

Next, configure the database connection in `application.properties`:

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=root
spring.datasource.password=secret

Create a data access object (DAO) interface, for example, `UserMapper.java`:

@Mapper
public interface UserMapper {
    
    @Select("SELECT * FROM users")
    List<User> getAllUsers();
    
    // other CRUD methods...
}

Create a model class, for example, `User.java`:

public class User {
    
    private Long id;
    private String name;
    private String email;
    
    // getters and setters...
}

Finally, use the DAO in your service or controller, for example, `UserService.java`:

@Service
public class UserService {
    
    private final UserMapper userMapper;
    
    public UserService(UserMapper userMapper) {
        this.userMapper = userMapper;
    }
    
    public List<User> getAllUsers() {
        return userMapper.getAllUsers();
    }
    
    // other service methods...
}

That's it! You can now use MyBatis to interact with your database in a Spring Boot application. Remember to annotate your main class with `@MapperScan` to scan the mapper interfaces, and use the `@Autowired` annotation to inject the service or mapper beans where needed.

Hope this helps! Let me know if you have any more questions.
