Junit在Spring Boot中測試不會注入服務

我有一個基本的SpringBoot應用程序。使用Spring初始化程序，嵌入式Tomcat，Thymeleaf模板引擎和包作爲可執行JAR文件。Junit在Spring Boot中測試不會注入服務

我有這樣的服務：

@Service 
public class TdkRestApiService { 
    ... 
}

，我想測試：

@ContextConfiguration(classes={TdkApplicationConfig.class, TdkDevelopmentConfig.class}) 
@RunWith(SpringRunner.class) 
public class TdkRestApiServiceTests { 


    /** 
    * The object being tested. 
    */ 
    @Autowired 
    TdkRestApiService tdkRestApiService; 

    @Test 
    public void getCallbacksByDeviceTypeTest() throws IOException { 

     tdkRestApiService.getCallbacksByDeviceType("2", "3"); 

    } 
}

，但我得到了一個錯誤：

這解決我的問題：

@RunWith(SpringRunner.class) 
@SpringBootTest(classes = TdkApplication.class) 
public class SigfoxRestApiServiceTests { 
. 
}

這裏：

@ContextConfiguration 
@RunWith(SpringRunner.class) 
public class TdkRestApiServiceTests {

您不指定ContextConfiguration註釋的classes屬性。

您應該使用您的根Spring配置類設置此屬性，該類設置您的所有配置，特別是設置bean的TdkRestApiService。
例如，如果你的根彈簧的配置類是MyConfig，你可以指定它：

@ContextConfiguration(classes = MyConfig.class) 
@RunWith(SpringRunner.class) 
public class TdkRestApiServiceTests {

可以對Spring documentation discussing of detecting test configuration的更多信息。

下面的摘錄：

If you’re familiar with the Spring Test Framework, you may be used to using @ContextConfiguration(classes=…) in order to specify which Spring @Configuration to load. Alternatively, you might have often used nested @Configuration classes within your test.
