how to test rest controller with custom spring DispatcherServlet - spring

Question

I'm trying to test my controller and I want to my custom DispatcherServlet include on that.
my dispatcher is something like this:
public class LoggableDispatcherServlet extends DispatcherServlet {
private static final Logger LOGGER = LoggerFactory.getLogger(LoggableDispatcherServlet.class);
#Autowired
private LogsService logsService;
#Override
protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws
Exception
{
.
.
.
mapper.readTree(requestWrapper.getContentAsByteArray());
int status = responseWrapper.getStatus();
JsonNode newNode = mapper.readTree(responseWrapper.getContentAsByteArray());
JsonNode responseJson= newNode;
logsService.addLogs(request,response ,...)
}
}
and my test Class is something like this:
#SpringBootTest
#RunWith(SpringRunner.class)
public class RestControllerTest {
private final Resource test1 = new ClassPathResource("test1.json");
private MockMvc mockMvc;
#Autowired
private RestTemplate restTemplate;
#Autowired
private WebApplicationContext wac;
#BeforeEach
public void before() {
mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
this.mockRestServiceServer = MockRestServiceServer.bindTo(this.restTemplate)
.build()
}
#Test
public void getAvailableLoanTest() throws Exception{
String url1="http://localhost:80801/testService?param1=1&param2=2";
this.mockRestServiceServer
.expect(ExpectedCount.manyTimes(), requestTo(url1))
.andExpect(method(HttpMethod.GET))
.andRespond(withSuccess(this.test1, MediaType.APPLICATION_JSON_UTF8));
this.mockMvc.perform(post("/api/myApi")
.contentType(MediaType.APPLICATION_JSON)
.content(asJsonString(new MyRequest(1, 2,))))
.andExpect(status().is2xxSuccessful())
.andExpect(content().contentType("application/json"))
//.andExpect(jsonPath("#.res1").value(1L))
.andReturn();
.
.
.
}
}
The problem is my request receive directly by rest controller and I can't test the DispatcherServlet.
I'm using spring boot 2.2.3 with jar packaging and I don't have web.xml or any servlet configration.
