Java 配置嵌入式MongoDB的最简单方法

我想知道，是否有任何示例可以正确配置嵌入式

MongoDB

和

springboot

例如，我是这样配置H2嵌入式数据库的：

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();
    }
}

这很有效，但有一个问题。这种方法不提供MongoDB的配置

有什么解决办法吗

更新1:

package com.reborn.xxx.config;

import com.mongodb.MongoClient;
import cz.jirutka.spring.embedmongo.EmbeddedMongoFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.core.MongoTemplate;

import java.io.IOException;

@Configuration
public class DataSourceConfig {

    @Bean
    public MongoTemplate mongoTemplate() throws IOException {
        EmbeddedMongoFactoryBean mongo = new EmbeddedMongoFactoryBean();
        mongo.setBindIp("localhost");
        MongoClient mongoClient = mongo.getObject();
        MongoTemplate mongoTemplate = new MongoTemplate(mongoClient, "abcd");
        return mongoTemplate;
    }

}

可以与弹簧护套集成

• 声明对活板门的依赖关系：

  <dependency>
      <groupId>de.flapdoodle.embed</groupId>
      <artifactId>de.flapdoodle.embed.mongo</artifactId>
      <version>2.0.0</version>
  </dependency>
  

• 现在，只需配置一个指向嵌入式MongoDB实例的

  MongoTemplate

  ：

  @Bean
  public MongoTemplate mongoTemplate() throws IOException {
      EmbeddedMongoFactoryBean mongo = new EmbeddedMongoFactoryBean();
      mongo.setBindIp("localhost");
      MongoClient mongoClient = mongo.getObject();
      MongoTemplate mongoTemplate = new MongoTemplate(mongoClient, "test_or_whatever_you_want_to_call_this_db");
      return mongoTemplate;
  }

它将自动配置相关依赖项的新版本或兼容版本

mvn clean install
以确保一切正常运行，但正如您所看到的，仍然存在一个问题。您尚未指定为
de.flapdoodle.embed.mongo
依赖项提供了一个版本，这意味着，对于Spring Boot 1.5.6.RELEASE，您使用的是v1.50.5。我在我的帖子中使用v2.0.0验证了实现（即，我的答案中明确引用的版本）但是，
de.flapdoodle.embed.mongo
的v1.50.5还包括
IFeatureAwareVersion
，所以应该可以。AFAICT，您的设置是有效的，您可以在IDE中浏览到
IFeatureAwareVersion
吗？您是否检查过此文件：
de.flapdoodle.embed.mongo-1.50.5.jar
存在于您的本地Maven repo中，并且它包含
IFeatureAwareVersion
？
