用于单元测试的Spring mongo db配置

我尝试使用fongo进行单元测试，并在测试中添加了另一个mongo配置来替换原来的配置，但它不起作用

我按照一些教程来使用

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration

这两个注释用于测试类，我尝试了它，它失败了，bean创建错误如下：

java.lang.IllegalStateException: Failed to load ApplicationContext
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]
org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling
java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

这是我的测试课：

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = Controller.class)
public class ApplicationTests {
  @Autowired
  private WebApplicationContext webApplicationContext;

  private MockMvc mockMvc;

  @Before
  public void setUp() throws Exception {
    mockMvc = webAppContextSetup(webApplicationContext).build();
  }

  ... Tests here ...

  @After
  public void tearDown() throws Exception {
  }

  @Configuration
  @EnableMongoRepositories
  @ComponentScan(basePackageClasses = { RecorderRepository.class })
  static class MongoConfiguration extends AbstractMongoConfiguration {

    @Override
    protected String getDatabaseName() {
      return "test-db";
    }

    @Override
    public Mongo mongo() {
      return new Fongo("test").getMongo();
    }

    @Override
    protected String getMappingBasePackage() {
      return "com.mongo.test";
    }
  }
}

我正在使用SpringDataMongoDB:1.7.2.RELEASE，并通过在我的应用程序中调用mongoOperation而不是自动连接存储库来访问db。像这样

private AnnotationConfigApplicationContext context =
    new AnnotationConfigApplicationContext(MongoConfig.class);
private MongoOperations mongoOperation =
    (MongoOperations) context.getBean("mongoTemplate");

这是原因吗

@ComponentScan(basePackageClasses = { RecorderRepository.class })

不工作

我应该怎么做才能让它工作？如果您能提供任何帮助，我将不胜感激

=============================================================

更新：

我尝试了嵌入式mongodb，仍然遇到无法连接到数据库的问题。我还需要设置其他内容吗？还是添加注释

以下是我的配置：

static class MongoConfiguration extends AbstractMongoConfiguration {
  private MongodStarter starter = MongodStarter.getDefaultInstance();

  @Override
  public Mongo mongo() throws Exception {
    return new MongoClient("localhost", 12345);
  }

  @Bean(destroyMethod = "stop")
  public MongodProcess mongod() throws IOException {
    return mongodExe().start();
  }

  @Bean(destroyMethod = "stop")
  public MongodExecutable mongodExe() throws IOException {
    return starter.prepare(mongodConfig());
  }

  @Bean
  public IMongodConfig mongodConfig() throws IOException {
    return new MongodConfigBuilder().version(Version.Main.PRODUCTION)
                                    .net(new Net(12345,Network.localhostIsIPv6()))
                                    .build();
  }
}

我从来没用过丰戈。不过，我已经做了这件事

这是为配合弹簧靴使用而设计的。Embedded Mongo启动，并设置

MongoProperties

以连接到嵌入式实例。如果您没有使用Spring Boot，那么您将需要更新负责mongo连接的任何配置，而不是更新

MongoProperties

。

感谢您的分享，我稍后会尝试。我需要在测试类中添加或调整任何注释吗？我用新配置更新了问题。你有什么办法让它工作吗？谢谢
