SpringBoot中使用@WebMvcTest时如何排除特定的xml配置？

Question

我想测试我的控制器层，所以我使用了@WebMvcTest 注解，因为我不想启动整个服务器。但是当我运行控制器测试时，测试总是失败。我的 ControllerTest 代码如下：

@RunWith(SpringRunner.class)
@WebMvcTest(value = ServiceController.class)
public class ServiceControllerTest {

private MockMvc mockMvc;

@Autowired
private WebApplicationContext webApplicationContext;

@MockBean
private CloudServiceFacade cloudServiceFacade;

@Before
public void setUp() throws Exception {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}

@Test
public void checkRoleExist() throws Exception {
}
}

一条错误消息，例如：

我可以理解错误信息，因为在我的应用程序中（我使用SpringBoot），我有一个Bootstrap类，它是应用程序的入口。 Bootstrap 类是这样的：

@SpringBootApplication(scanBasePackages = {"com.netease.permission"})
@ImportResource("classpath:applicationContext.xml")
public class Bootstrap {
public static void main(String[] args) {
    SpringApplication.run(Bootstrap.class);
}
}

它导入一个外部xml：applicationContext.xml，applicationContext.xml如下：

 <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans.xsd">

<import resource="database.xml" />
<import resource="tools.xml" />
<import resource="dubbo-service.xml" />
<import resource="spring-mvc.xml" />

</beans>

问题是我不想导入整个 applicationContext.xml，因为它定义了整个额外的资源依赖，比如 mysql\redis\zk 等。但只有 spring-mvc.xml.Cause 在 spring-mvc.xml 我定义了拦截器。我想在我的 ServiceControllerTest 中测试拦截器和控制器。

我已经添加了@TestConfiguration("classpath:spring-mvc.xml") 表示我只想导入spring-mvc.xml配置，但是不起作用。

有没有人遇到过我的情况，有人能帮忙吗？

只需将具有相同文件名的空弹簧上下文文件放入 src/test/resource 文件夹中。这应该覆盖原来的。
