使用@WebMvcTest进行测试时的ApplicationContext异常

我有一个Spring Boot应用程序(1.5.10.RELEASE),其中包含一个main(SpringBootApplication),如下所示:

@SpringBootApplication
@Configuration
@EntityScan(basePackages = { "db.modell", "db.modell.base" })
@ComponentScan(basePackages = { "de.gui.test" })
public class SpringBootConsoleApplication {
   public static void main(String[] args) throws Exception {
    SpringApplication.run(SpringBootConsoleApplication.class, args);
  }
}

和两个REST控制器如下:

@RestController
@RequestMapping("/as")
public class AController {
  @Autowired
  private ARepository aRepository;

  @RequestMapping(method = RequestMethod.GET)
  public ResponseEntity<Collection<A>> getAs() {
    return new ResponseEntity<>(orgtFarbeRepository.findAll(), HttpStatus.OK);
  }

  @RequestMapping(value = "/{id}", method = RequestMethod.GET)
  public ResponseEntity<A> getA(@PathVariable long id) {
    A a = ARepository.findOne(id);

    if (party != null) {
      return new ResponseEntity<>(ARepository.findOne(id), HttpStatus.OK);
    } else {
      return new ResponseEntity<>(null, HttpStatus.NOT_FOUND);
    }
  }
}

此外,我有一个这样的测试:

@RunWith(SpringRunner.class)
@WebMvcTest(AController.class)
public class AControllerTest {

  @Autowired
  private MockMvc mvc;

  @MockBean
  private ARepository ARepository;

  @Test
  public void firstTest() throws Exception {
    A a = new aFarbe();
    a.set....
    when(ARepository.findAll()).thenReturn(Collections.singleton(a));
    mvc.perform(
            get("/as")
            .accept(MediaType.APPLICATION_JSON_UTF8_VALUE)
    )
      .andExpect(status().isOk());
  }
}

存储库看起来像这样:

public interface ARepository extends CrudRepository<A, Long>
{
    Collection<A> findAll();
}
public interface BRepository extends CrudRepository<B, Long>
{
  Collection<B> findAll();
}

A和B他们自己是JPA注释类。整个应用程序包含对数据库的访问..

此外,我有这样的服务:

@Service
public class XService {
  private static final Logger LOGGER = LoggerFactory.getLogger(XService.class);

  @Autowired
  private ARepository aRepository;

  @Autowired
  private BRepository bRepository;
...
}

XService不是通过@Autowire左右使用的(只需删除它):

所以我尝试运行AControllerTest,我收到以下错误:

  

java.lang.IllegalStateException:无法加载ApplicationContext   org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:124)   .. .. 在   org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:206)   引起:   org.springframework.beans.factory.UnsatisfiedDependencyException:   创建名为“XService”的bean时出错:不满意的依赖项   通过字段“BRepository”表达;嵌套异常是   org.springframework.beans.factory.NoSuchBeanDefinitionException:没有   可以使用'BRepository'类型的限定bean:预计至少为1   豆有资格作为autowire候选人。依赖注释:   {@ org.springframework.beans.factory.annotation.Autowired(所需=真)}   .. .. 在   org.springframework.boot.test.context.SpringBootContextLoader.loadContext(SpringBootContextLoader.java:120)   在   org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContextInternal(DefaultCacheAwareContextLoaderDelegate.java:98)   在   org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:116)   ... 26更多引起:   org.springframework.beans.factory.NoSuchBeanDefinitionException:没有   可以使用'BRepository'类型的限定bean:预计至少为1   豆有资格作为autowire候选人。依赖注释:   {@ org.springframework.beans.factory.annotation.Autowired(所需=真)}   在   org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1493)   在   org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1104)   在   org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1066)   在   org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor $ AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:585)   ... 44更多

我的假设是,在测试期间,更多的上下文开始了。问题是如何防止这种情况?这意味着只启动AControler的上下文而已?我认为基于@WebMvcTest(AController.class)它应该是有限的,看起来不是这样......

1 个答案:

答案 0 :(得分:2)

引用的答案并没有真正回答我的问题,但在上下文中hint给了我解决方案。这意味着在我的测试中添加以下内容:

所以我必须添加@OverrideAutoConfiguration(enabled=true)

@RunWith(SpringRunner.class)
@WebMvcTest(OrgtFarbenController.class)
@OverrideAutoConfiguration(enabled=true)
public class AControllerTest {
...
}
