配置嵌入式MongoDB的最简单方法

问题描述

我想知道，有没有示例如何使用Spring Boot正确配置嵌入式MongoDB?

I'm wondering, is there any example how to properly configure embedded MongoDB with Spring Boot?

例如，这是我配置H2嵌入式数据库的方式:

For example, this is how i configure H2 embedded database:

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.

And this works well, but there is a problem. This approach doesnt provide configuration with MongoDB.

有没有解决方法?

推荐答案

flapdoodle嵌入式MongoDB 可以与Spring Boot集成.

The flapdoodle embedded MongoDB can be integrated with Spring Boot.

• 声明对flappedoodle的依赖:

• Declare a dependency on flapdoodle:

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

声明对该库的依赖关系，以便为flappoodle的嵌入式MongoDB提供Spring工厂bean:

Declare a dependency on the library, to provide a Spring factory bean for flapdoodle's embedded MongoDB:

<dependency>
    <groupId>cz.jirutka.spring</groupId>
    <artifactId>embedmongo-spring</artifactId>
    <version>1.3.1</version>
</dependency>

大概是您已经声明了对spring-boot-starter-data-mongodb的依赖关系:

Presumably, you have already declared a dependency on spring-boot-starter-data-mongodb:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

现在，只需配置指向嵌入式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;
}
