ApplicationContext無法在單元測試中自動裝配

Question

我正在為@Configuration類編寫測試，並且在自動裝配ApplicationContext時崩潰。 軟件包中只有一個Config類。 奇怪的是，bean在正常執行中工作。

這是測試的基礎。

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AWSConfig.class)
@TestPropertySource(properties = {""})
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
@PowerMockIgnore({"javax.management.*", "sun.*", "javax.net.ssl.*"})
@PrepareForTest({AWSConfig.class})
@ComponentScan(basePackages = {"com.mycompany..."})
public class AppConfigTest {

    @Autowired
    private ApplicationContext context;

由於無法加載上下文而導致失敗，根本原因是找不到類。

Answer 1

使用@ComponentScan(basePackages = {"com.mycompany.*"})而不是@ComponentScan(basePackages = {"com.mycompany..."})

要么

只需使用@ComponentScan("com.mycompany.*")
