将@SpyBean与 Spring 启动测试结合使用@Qualifier

Question

我的应用程序中有 2 个DataSource。

所以，为了获得所需的JdbcTemplate，我使用@Qualifier.但是，当我像下面一样时，测试运行...但如果在"测试方法"中使用了JdbcTemplate，则会无限期地等待。

@Service
@Transactional
public class SampleDatabaseService {
    @Autowired
    @Qualifier("firstDbJdbcTemplate")
    private JdbcTemplate firstDbJdbcTemplate;
    @Autowired
    @Qualifier("secondDbJdbcTemplate")
    private JdbcTemplate secondDbJdbcTemplate;
    @Cacheable("status")
    public Map<String, Device> readAllValidDeviceStatus() {
        Map<String, Device> allDeviceStatuses = new HashMap<>();
        //Stops at below line indefinitely if "SpyBean" is used
        List<StatusDetail> statusDetails = firstDbJdbcTemplate
               .query(SqlQueries.READ_DEVICE_STATUS, BeanPropertyRowMapper.newInstance(StatusDetail.class)); 
        statusDetails
               .stream()
               .filter(deviceStatus -> deviceStatus.getName() != "Some Invalid Name")
               .forEach(deviceStatus -> allDeviceStatuses
                  .put(deviceStatus.getName(), buildDevice(deviceStatus)));
        return allDeviceStatuses;
    }
/** More Stuff **/
}

和测试：

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Transactional
@Rollback
@ActiveProfiles("test")
public class SampleDatabaseServiceTest {
    @SpyBean
    @Qualifier("firstDbJdbcTemplate")
    private JdbcTemplate firstDbJdbcTemplate;
    @Autowired
    private SampleDatabaseService serviceUnderTest;
    @Before
    public void populateTables() {
        //Insert some Dummy Records in "InMemory HSQL DB" using firstDbJdbcTemplate
    }

    @Test
    public void testReadAllValidDeviceStatus() {
        // When
        Map<String, Device> allDeviceStatuses = serviceUnderTest.readAllValidDeviceStatus();
        // Then
        assertThat(allDeviceStatuses).isNotNull().isNotEmpty();
        // More checks
    }
    /* More Tests */
}

但是，当我在 Test 中用 @Autowired 替换@SpyBean时，它工作正常。

为什么会这样？任何帮助将不胜感激。:)

Answer 1

以以下格式使用它

  @MockBean(name = "firstDbJdbcTemplate") 
  private JdbcTemplate firstDbJdbcTemplate;

Answer 2

您可以简单地使用SpyBean注释name属性

@SpyBean(name = "firstDbJdbcTemplate")
private JdbcTemplate firstDbJdbcTemplate;
