我想知道，有没有如何正确配置嵌入式任何例如MongoDB用Spring Boot？

例如，这就是我配置H2嵌入式数据库的方式：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseBuilder;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType;
import org.springframework.jndi.JndiObjectFactoryBean;

import javax.sql.DataSource;


@Configuration
@PropertySource({"configs/datasource.properties"})
public class DataSourceConfig {

    @Bean
    @Profile("test")
    public DataSource testDataSource() {
        return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).build();
    }
}

这很好用，但是有一个问题。这种方法不提供MongoDB的配置。

有什么解决方法吗？
