如何在Spring Boot中配置类似H2数据库的mongoDB的内存嵌入式数据库

<dependency>

import org.springframework.data.annotation.Id;

@Document(collection = "users")
public class User {
    @Id
    private String id;

    private int age;
    
    // 省略getter和setter方法
}

import org.springframework.data.mongodb.repository.MongoRepository;

public interface UserRepository extends MongoRepository<User, String> {
    // 可以在这里定义自定义的查询方法
}
