java - 无法将服务注入(inject) Spring 测试

Question

financialReportService 在 REST Controller 中为空，表示注入(inject)失败。

测试:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = SnapshotfindocApp.class)
public class FindocResourceIntTest {
@Inject
    private FinancialReportService financialReportService; 
@Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        FindocResource findocResource = new FindocResource();
        ReflectionTestUtils.setField(findocResource, "findocRepository", findocRepository);
        this.restFindocMockMvc = MockMvcBuilders.standaloneSetup(findocResource)
            .setCustomArgumentResolvers(pageableArgumentResolver)
            .setMessageConverters(jacksonMessageConverter).build();
    }


@Test
    @Transactional
    public void getFinancialRecords() throws Exception {

        // Get all the financial-reports
        restFindocMockMvc.perform(get("/api/financial-reports"))
            .andExpect(status().isOk());
        List<Findoc> finReports = financialReportService.getFinancialReports();
        for (Findoc fr : finReports) {
            assertThat(fr.getNo_months()).isBetween(12, 18);
            LocalDate documentTimeSpanLimit = LocalDate.now().minusMonths(18);
            assertThat(fr.getFinancial_date()).isAfterOrEqualTo(documentTimeSpanLimit);
        }
    }

服务:

@Service
@Transactional
public class FinancialReportService {

    private final Logger log = LoggerFactory.getLogger(FinancialReportService.class);

    @Inject
    private FinancialReportDAO financialReportDAO;

    public List<Findoc> getFinancialReports(){
        return financialReportDAO.getFinancialReports();
    }

}

Controller :

@GetMapping("/financial-reports")
    @Timed
    public List<Findoc> getFinancialReports() {
        log.debug("REST request to get financial records");
        return financialReportService.getFinancialReports(); // financialReportService is null
    }

更新:

该应用程序由 JHipster 生成。然后 new service和 DAO 文件被添加以启用对 H2 的自定义数据库查询。

@Inject服务后，还需要在setup()方法中设置字段。添加以下行应该可以解决您的问题

ReflectionTestUtils.setField(findocResource, "financialReportService", financialReportService);

另外，测试的以下部分看起来很奇怪。您正在两次获取财务报告。此文件是 FindocResourceIntTest，因此我将删除对 financialReportService 的任何直接调用。

    // Get all the financial-reports
    restFindocMockMvc.perform(get("/api/financial-reports"))
        .andExpect(status().isOk());
    List<Findoc> finReports = financialReportService.getFinancialReports();
