如何在内存中嵌入MariaDB4j来替换JUnit测试中的默认Spring DataSource？

<dependency>
    <groupId>ch.vorburger.mariaDB4j</groupId>
    <artifactId>mariaDB4j</artifactId>
    <version>2.4.0</version>
    <scope>test</scope>
</dependency>

@Configuration
public class TestDataSourceConfig {

    @Bean
    public DataSource dataSource() throws ManagedProcessException {
        DB db = DB.newEmbeddedDB(3306);
        db.start();
        
        // 创建一个内存数据库
        db.createDB("testdb");
        
        // 获取内存数据库的连接信息
        ConnectionInfo connectionInfo = db.getConfiguration().getURL("testdb");
        
        // 创建一个基于内存数据库连接信息的DataSource
        HikariConfig hikariConfig = new HikariConfig();
        hikariConfig.setJdbcUrl(connectionInfo.toString());
        hikariConfig.setUsername(connectionInfo.getUser());
        hikariConfig.setPassword(connectionInfo.getPassword());
        
        return new HikariDataSource(hikariConfig);
    }
}

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = TestDataSourceConfig.class)
public class MyTest {

    @Autowired
    private DataSource dataSource;

    // 测试代码...
}
