Mockito再放心：mock dao存储库

Question

@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = {VedicaConfig.class})
@AutoConfigureMockMvc
@ActiveProfiles("test")
public class RESTTest {
@LocalServerPort
    private int port;

    @Autowired
    private MockMvc mvc;

    @Mock
    MetaVersionDAO metaVersionDAO;

    @InjectMocks
    DocCtrl docCtrl;

    @Before
    public void contextLoads() {
        RestAssured.port = port;
        assertThat(mvc).isNotNull();

        // this must be called for the @Mock annotations above to be processed.
        MockitoAnnotations.initMocks(this);
        RestAssuredMockMvc.standaloneSetup(MockMvcBuilders.standaloneSetup(docCtrl));
    }

    @Test
    public void shouldGetThumbnail() {
        String ver = "1.0";
        String uuid = "124-wqer-365-asdf";
        when(metaVersionDAO.getMetaByVersionUUID(ver, uuid)).thenReturn(new DocVersion());

        given()
                .when()
                .param("uuid", uuid)
                .param("versionVed", ver)
                .get(CTX_BASE + "/thumbnail")
                .then()
                .log().ifValidationFails()
                .statusCode(OK.value())
                .contentType(ContentType.BINARY);
    }

}

    public RawDocument getDocThumbnail(String uuid, String versionVed) throws Exception {
        DocVersion docVersion = metaVersionDAO.getMetaByVersionUUID(versionVed, uuid);
        InputStream inputStream = okmWebSrv.getOkmService().getContentByVersion(uuid, versionVed);
        String dataType = docVersion.getMetadata().getAdditionals().get(Vedantas.CONTENT_TYPE);
        ByteArrayInputStream bais = new ByteArrayInputStream(createPDFThumbnail(dataType, inputStream));

        RawDocument rawDocument = new RawDocument(bais, "qwer");
        return rawDocument;
    }

正如您所看到的，我尝试在@test方法的顶部模拟metaversiondao，所以我希望它返回我设置的new DocVersion()，但是在这个DAO中调用的是实际的代码，它在entityManager上失败，它是null。

我的问题是为什么metaversiondao.getMetabyVersionUuid不返回我的模拟对象，我应该做些什么来使其返回？

谢了！

通过将@mock更改为@mockbean来解决。

事实就是如此：

    @MockBean
    MetaVersionDAO metaVersionDAO;

其他一切都与post中的一样，它使用了mocked实例。
