mybatis example

Sure! Here's a simple example of using MyBatis:

First, you need to set up your database connection and create a configuration file for MyBatis. In this example, let's assume you have a table called "users" with columns "id" and "name".

1. Create a configuration file named "mybatis-config.xml" with the following content:

<configuration>
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/mydatabase"/>
                <property name="username" value="your_username"/>
                <property name="password" value="your_password"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <mapper resource="UserMapper.xml"/>
    </mappers>
</configuration>

2. Create a Java class called "User" representing the users table:

public class User {
    private int id;
    private String name;

    // Getters and setters
}

3. Create a mapper XML file named "UserMapper.xml" with the following content:

<mapper namespace="com.example.UserMapper">
    <resultMap id="userResultMap" type="User">
        <id property="id" column="id"/>
        <result property="name" column="name"/>
    </resultMap>

    <select id="getUserById" resultMap="userResultMap">
        SELECT id, name FROM users WHERE id = #{id}
    </select>

    <insert id="insertUser" parameterType="User">
        INSERT INTO users (name) VALUES (#{name})
    </insert>
</mapper>

4. Create an interface called "UserMapper" with the following content:

public interface UserMapper {
    User getUserById(int id);
    void insertUser(User user);
}

5. Finally, you can use MyBatis in your Java code:

public class Main {
    public static void main(String[] args) {
        // Create a SqlSessionFactory
        InputStream inputStream = Resources.getResourceAsStream("mybatis-config.xml");        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);

        // Create a SqlSession
        try (SqlSession session = sqlSessionFactory.openSession()) {
            // Get the UserMapper instance
            UserMapper userMapper = session.getMapper(UserMapper.class);
            // Get a user by ID
            User user = userMapper.getUserById(1);
            System.out.println(user.getName());

            //
