使用Fongo进行单元测试时，无法创建“mongoMappingContext”Bean

时间：2016-04-28 16:23:12

标签： spring mongodb unit-testing junit fongo

我正在为我正在进行的项目设置单元测试，我遇到了一些问题。我正在研究的项目是使用mongoDB作为其数据库，因此对于单元测试，我想使用Fongo来模拟数据库，这样我就可以测试功能本身。但是每当我运行测试时，它都无法正确创建mongoMappingContext Bean，测试本身也会失败。根本原因是mappingException，但我不是导致它的原因。有没有其他人在与Fongo进行单元测试时经历过类似的事情？感谢您提供所有帮助！

测试数据库配置文件，TestDatabaseConfiguration.java：

@Configuration
@Import(value = MongoAutoConfiguration.class)
@PropertySource("classpath:application.properties")
@EnableMongoAuditing(auditorAwareRef = "springSecurityAuditorAware")
@EnableMongoRepositories("com.x.repository")
@ComponentScan(basePackages = {"com.x.service", "com.x.utility"})
public class TestDatabaseConfiguration extends AbstractMongoConfiguration {
    private final Logger logger = LoggerFactory.getLogger(TestDatabaseConfiguration.class);

    @Override
    protected String getDatabaseName() {
        return "test_app";
    }

    @Override
    public Mongo mongo() throws Exception {
        // uses fongo for in-memory tests
        return new Fongo("mongo-test").getMongo();
    }

    @Override
    protected String getMappingBasePackage() {
        return "com.x.service";
    }

    @Override
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongo(), "test_app");
    }

    @Bean
    public CustomConversions customConversions() {
        List<Converter<?, ?>> converterList = new ArrayList<>();
        OAuth2AuthenticationReadConverter converter = new OAuth2AuthenticationReadConverter();
        converterList.add(converter);
        return new CustomConversions(converterList);
    }

    @Bean
    public MongoMappingContext mongoMappingContext() throws ClassNotFoundException {
        MongoMappingContext mappingContext = new MongoMappingContext();
        mappingContext.setInitialEntitySet(getInitialEntitySet());
        mappingContext.setSimpleTypeHolder(customConversions().getSimpleTypeHolder());
        mappingContext.setFieldNamingStrategy(fieldNamingStrategy());

        return mappingContext;
    }

    @Bean
    public MongoDbFactoryBean dbFactoryBean() throws Exception {

        MongoDbFactoryBean dbFactoryBean = new MongoDbFactoryBean();
        dbFactoryBean.setMongo(mongo());

        dbFactoryBean.setName("test_app");

        logger.info("Application database: {}", "test_app");

        return dbFactoryBean;
    }
}

测试文件MarketingAutomationServiceTest.java：

@ContextConfiguration(classes = {TestDatabaseConfiguration.class})
@RunWith(SpringJUnit4ClassRunner.class)
public class MarketingAutomationServiceTest extends TestCase {

    @Autowired
    private MarketingAutomationService marketingAutomationService;

    @Test
    @UsingDataSet(locations = {"/one-marketing-automation-query.json"}, loadStrategy = LoadStrategyEnum.CLEAN_INSERT)
    public void testGetQuery(){
        MarketingAutomationQuery result = marketingAutomationService.getQuery("555a3662e4b024fe6d7a9d3f");

        assertNotNull(result);
    }
}

每当我运行测试时，我从Spring获得的错误跟踪：

mongoMappingContext（）方法已经过了你正在扩展的抽象类，即AbstractMongoConfiguration。我有类似的设置，大多数属性似乎正确，除了你配置文件中有2个额外的bean。 CustomConversions和MongoMappingContext。

您可以尝试在测试配置文件TestDatabaseConfiguration.java中再次删除正在创建的Bean吗？

@Bean
public MongoMappingContext mongoMappingContext()

@Bean
public CustomConversions customConversions()
