How to exclude specific xml configuration when using @WebMvcTest in SpringBoot?

Question

I want to test my controller layer, so I used @WebMvcTest annotation, because I don't want startup the whole server. But when I ran the controller test, the test is always failed. My ControllerTest code like this:

@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 {
}
}

A piece of error messages like :

I can understand the error message, because in my application（I use SpringBoot), I have a Bootstrap class which is the entrance of the application. The Bootstrap class like this:

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

It import a external xml: applicationContext.xml, and applicationContext.xml is below:

 <?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>

The problem is I don't want import the whole applicationContext.xml, cause it define the whole extra resource dependency, like mysql\redis\zk,etc. but only spring-mvc.xml.Cause in spring-mvc.xml I define the interceptors. I want test the interceptors & controller in my ServiceControllerTest.

I have already add @TestConfiguration("classpath:spring-mvc.xml") indicate that I only wanna import spring-mvc.xml configuration, but it doesn't work.

Does anyone encounter my situation, could anyone body help?

Just put an empty spring context file with the same file name into src/test/resource folder. This should override the original one.
