如何在Spring Data MongoDB中使用存储库方法构建一些测试?我想为我的测试设置测试数据库,因为我不想为此目的使用生产数据库。应该可能,但我不知道。这是我的应用程序上下文:

<mongo:repositories base-package="domain.company.group.project.data.repositories.mongodb"/>
<!-- some other stuff -->
</beans>
让我说我有一个简单的存储库如下:
public interface LocationRepository extends MongoRepository<Location, String>, LocationRepositoryCustom {
}
其中LocationRepositoryImpl是实现某个Location(域对象)类的所有自定义方法的类。我的测试类看起来像:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/test-context.xml"})
public class LocationRepositoryTest {
@Autowired
private LocationRepository locationRepository;
/* Some tests... */
}
我试图在我的运行测试中嵌入一个MongoDB实例(如here所解释的那样)但它不起作用:建立了与测试数据库的连接但是mongo模板似乎无法覆盖所有保存方法继续将数据插入“生产”数据库。
我使用的是Spring 3.2.0和Spring Data Mongo 1.1.0.RELEASE。我正在使用Junit进行测试。
有什么建议吗?
提前谢谢。

Jaranda,
上周我遇到了同样的问题,巧合的是我听说过Fongo,“mongo的内存中java实现。”
所以我决定用它来测试我的自定义存储库并且对我很有效。下面是如何配置Spring以在JUnit测试中使用Fongo的示例。请注意,我没有使用xml配置。
希望这会有用!
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class LocationRepositoryTest {
private static final String PLAYER_ID = ObjectId.get().toString();
@Autowired private LocationRepositoryCustom playerRepository;
@Autowired private MongoTemplate mongoTemplate;
/* Some tests... */
@Configuration
static class LocationRepositoryTestConfiguration {
@Bean
public Mongo mongo() {
// Configure a Fongo instance
return new Fongo("mongo-test").getMongo();
}
@Bean
public MongoTemplate mongoTemplate() {
return new MongoTemplate(mongo(), "collection-name");
}
@Bean
public LocationRepositoryCustom playerRepository() {
// This is necessary if MongoTemplate is an argument of custom implementation constructor
return new LocationRepositoryCustomImpl(mongoTemplate());
}
}
}
