我无法在spring boot 1.4中运行简单的测试.我按照官方网站testing-the-spring-mvc-slice的教程,但我没有得到它的工作.
每次我收到以下错误：
java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration,you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
任何想法,提示？
提前致谢
编辑：
这是控制器
@Controller
public class UserManagementController {
@GetMapping(value = "/gs/users/getUsers")
public @ResponseBody String getAllUsers() {
return "test";
}
}
这是考验
@RunWith(SpringRunner.class)
@WebMvcTest(UserManagementController.class)
public class UserManagementControllerTest {
@Autowired
private MockMvc mvc;
@Test
public void showUserView() throws Exception {
this.mvc.perform(get("/gs/users/getUsers"))
.andExpect(status().isOk())
.andDo(print());
}
}
从我的观点来看,它与网站上的这篇文章完全相同.
@WebMvcTest将执行：
>自动配置Spring MVC,Jackson,Gson,消息转换器等.
>加载相关组件(@ Controller,@ RestartController,@ JsonComponent等)
>配置MockMVC
现在为什么我需要配置一个“超级”类
The search algorithm works up from the package that contains the test
until it finds a @SpringBootApplication or @SpringBootConfiguration
annotated class. As long as you’ve structure your code in a sensible
way your main configuration is usually found.
所以你用@ * Test注释了你的测试.它运行,检查子类中的配置,没有找到任何,抛出异常.
您必须在测试类的包或子包中具有配置,或者直接将配置类传递给@ContextConfiguration或@SpringBootTest,或者使用@SpringBootApplication注释类.
根据@SpringBootApplication.我已经使用@WebMvcTest提到的方式测试了控制器：如果应用程序将类注释为@SpringBootApplication,则它会起作用,如果没有,则会出现异常.你提到的文章有评论：
In this example,we’ve omitted classes which means that the test will
first attempt to load @Configuration from any inner-classes,and if
that fails,it will search for your primary @SpringBootApplication
class.
Github discussion大致相同.
