我有一个基本的SpringBoot" title="SpringBoot">SpringBoot应用程序。使用Spring

Initializer，嵌入式Tomcat，Thymeleaf模板引擎以及作为可执行JAR文件的软件包。

我有这项服务：

@Service
public class TdkRestApiService {
    ...
}

我要测试的：

@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");
    }
}

但我得到一个错误：

ERROR o.s.test.context.TestContextManager - Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@dd3b207] to prepare test instance [com.tdk.backend.service.TdkRestApiServiceTests@6db9f5a4]

回答：

这解决了我的问题：

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