如何在Spring Boot应用程序中配置Embedded MongDB以进行集成测试？

如果由于任何原因无法使用它，请继续阅读。

测试类别：

    @RunWith(SpringJUnit4ClassRunner.class)    @SpringApplicationConfiguration(classes = {        Application.class,         TestMongoConfig.class // <--- Don't forget THIS    })    public class GameRepositoryTest {        @Autowired        private GameRepository gameRepository;        @Test        public void shouldCreateGame() { Game game = new Game(null, "Far Cry 3"); Game gameCreated = gameRepository.save(game); assertEquals(gameCreated.getGameId(), gameCreated.getGameId()); assertEquals(game.getName(), gameCreated.getName());        }    }

简单的MongoDB存储库：

public interface GameRepository extends MongoRepository<Game, String>     {    Game findByName(String name);}

MongoDB测试配置：

import com.mongodb.Mongo;import com.mongodb.MongoClientOptions;import de.flapdoodle.embed.mongo.MongodExecutable;import de.flapdoodle.embed.mongo.MongodProcess;import de.flapdoodle.embed.mongo.MongodStarter;import de.flapdoodle.embed.mongo.config.IMongodConfig;import de.flapdoodle.embed.mongo.config.MongodConfigBuilder;import de.flapdoodle.embed.mongo.config.Net;import de.flapdoodle.embed.mongo.distribution.Version;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.autoconfigure.mongo.MongoProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import java.io.IOException;@Configurationpublic class TestMongoConfig {    @Autowired    private MongoProperties properties;    @Autowired(required = false)    private MongoClientOptions options;    @Bean(destroyMethod = "close")    public Mongo mongo(MongodProcess mongodProcess) throws IOException {        Net net = mongodProcess.getConfig().net();        properties.setHost(net.getServerAddress().getHostName());        properties.setPort(net.getPort());        return properties.createMongoClient(this.options);    }    @Bean(destroyMethod = "stop")    public MongodProcess mongodProcess(MongodExecutable mongodExecutable) throws IOException {        return mongodExecutable.start();    }    @Bean(destroyMethod = "stop")    public MongodExecutable mongodExecutable(MongodStarter mongodStarter, IMongodConfig iMongodConfig) throws IOException {        return mongodStarter.prepare(iMongodConfig);    }    @Bean    public IMongodConfig mongodConfig() throws IOException {        return new MongodConfigBuilder().version(Version.Main.PRODUCTION).build();    }    @Bean    public MongodStarter mongodStarter() {        return MongodStarter.getDefaultInstance();    }}
