Config ServletRegistrationBean in #SpringBootApplication main class, test with mockmvc response 404 - mockmvc

Question

spring boot version is 2.0.0.RELEASE.
test class:
#RunWith(SpringRunner.class)
#SpringBootTest(classes={Application.class},webEnvironment=SpringBootTest.WebEnvironment.RANDOM_PORT)
#AutoConfigureMockMvc(secure = false)
public class ProcControllerTest {
#Autowired
private MockMvc mockMvc;
#Test
public void testGetProc() throws Exception {
String requestUrl = "/app/rest/query/proc";
// Request json body
JSONObject jsonBody = new JSONObject();
jsonBody.put("id", "101");
String contentBody = jsonBody.toJSONString();
MvcResult mvcResult = mockMvc.perform(post(requestUrl)
.contentType(MediaType.APPLICATION_JSON_UTF8)
.content(contentBody)
).andReturn();
MockHttpServletResponse response = mvcResult.getResponse();
assertThat(response.getStatus()).isEqualTo(200);
}
}
I alse tried another test config :
#RunWith(SpringRunner.class)
#SpringBootTest(classes = {Application.class},
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
//#AutoConfigureMockMvc(secure = false)
public class ProcessInstanceControllerMockMvcTest {
private MockMvc mockMvc;
#Autowired
private WebApplicationContext wac;
#Before
public void before() throws Exception {
mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
Application.class is below：
#SpringBootApplication
#Import({ApplicationConfiguration.class})
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder
builder) {
return builder.sources(Application.class);
}
#Bean
public ServletRegistrationBean apiDispatcher(){
DispatcherServlet api = new DispatcherServlet();
api.setContextClass(AnnotationConfigWebApplicationContext.class);
api.setContextConfigLocation(ApiDispatcherServletConfiguration.class.getName());
ServletRegistrationBean registrationBean = new ServletRegistrationBean();
registrationBean.setServlet(api);
registrationBean.addUrlMappings("/api/*");
registrationBean.setLoadOnStartup(1);
registrationBean.setAsyncSupported(true);
registrationBean.setName("api");
return registrationBean;
}
#Bean
public ServletRegistrationBean appDispatcher(){
DispatcherServlet app = new DispatcherServlet();
app.setContextClass(AnnotationConfigWebApplicationContext.class);
app.setContextConfigLocation(AppDispatcherServletConfiguration.class.getName());
ServletRegistrationBean registrationBean = new ServletRegistrationBean();
registrationBean.setServlet(app);
registrationBean.addUrlMappings("/app/*");
registrationBean.setLoadOnStartup(1);
registrationBean.setAsyncSupported(true);
registrationBean.setName("app");
return registrationBean;
}
}
The test run simple log is below :

Test Result :org.junit.ComparisonFailure: Expected :200 Actual :404
Through the above log, I guess the class TestDispatcherServlet is the reason. when I use TestRestTemplate, it does not init TestDispatcherServlet, and works fun.

Answer 1

MockMvc uses a DispatcherServlet different from the one registered by the app. The URLs you pass to it should be the exact same URLs you specified in your #Controller annotations.
