如何使用java代码以编程方式创建liquibase dbchangelog？

<dependency>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-core</artifactId>
    <version>4.5.0</version>
</dependency>

import liquibase.Liquibase;
import liquibase.database.Database;
import liquibase.database.DatabaseFactory;
import liquibase.database.jvm.JdbcConnection;
import liquibase.resource.ClassLoaderResourceAccessor;

// 创建数据库连接
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");

// 创建Liquibase实例
Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(new JdbcConnection(connection));
Liquibase liquibase = new Liquibase("path/to/changelog.xml", new ClassLoaderResourceAccessor(), database);

<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
                   http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-4.5.xsd">

    <changeSet id="1" author="John Doe">
        <createTable tableName="my_table">
            <column name="id" type="INT">
                <constraints primaryKey="true" nullable="false"/>
            </column>
            <column name="name" type="VARCHAR(100)"/>
        </createTable>
    </changeSet>

</databaseChangeLog>

liquibase.update("");
