java – Spring Boot测试中的MockBean批注导致NoUniqueBeanDefin

我在使用@MockBean注释时遇到问题.文档说MockBean可以替换上下文中的bean,但是我在单元测试中得到NoUniqueBeanDefinitionException.我看不出如何使用注释.如果我可以模拟repo,那么很明显会有多个bean定义.

我按照这里的例子来说：https://spring.io/blog/2016/04/15/testing-improvements-in-spring-boot-1-4

我有一个mongo存储库：

public interface MyMongoRepository extends MongoRepository<MyDTO,String>
{
   MyDTO findById(String id);
}

泽西岛资源：

@Component
@Path("/createMatch")
public class Create
{
    @Context
    UriInfo uriInfo;

    @Autowired
    private MyMongoRepository repository;

    @POST
    @Produces(MediaType.APPLICATION_JSON)
    public Response createMatch(@Context HttpServletResponse response)
    {
        MyDTO match = new MyDTO();
        match = repository.save(match);
        URI matchUri = uriInfo.getBaseUriBuilder().path(String.format("/%s/details",match.getId())).build();

        return Response.created(matchUri)
                .entity(new MyResponseEntity(Response.Status.CREATED,match,"Match created: " + matchUri))
                .build();
    }
}

还有一个JUnit测试：

@RunWith(SpringRunner.class)
@SpringBootTest
public class TestMocks {

    @Autowired
    private TestRestTemplate restTemplate;

    @MockBean
    private MyMongoRepository mockRepo;

    @Before
    public void setup()
    {
        MockitoAnnotations.initMocks(this);

        given(this.mockRepo.findById("1234")).willReturn(
                new MyDTO());
    }

    @Test
    public void test()
    {
        this.restTemplate.getForEntity("/1234/details",MyResponseEntity.class);

    }

}

错误信息：

Field repository in path.to.my.resources.Create required a single bean,but 2 were found:
    - myMongoRepository: defined in null
    - path.to.my.MyMongoRepository#0: defined by method 'createMock' in null

@MockBean(name="myMongoRepository")
private MyMongoRepository repository;

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)
