Java – spring boot w / embedded Tomcat does not send requests to the controller

I have an application using spring boot and embedded Tomcat container

As far as I know, my code is the same as spring boot sample project However, when I run the test, I get a 404 instead of 200 (in the case of trying to release, instead of receiving a 405, which is consistent with the correct setting of Tomcat):

Failed tests:
UserControllerTest.testMethod:45 Status expected:<200> but was:<404>

My java based configuration (some configuration classes are omitted):

@Configuration
@ComponentScan
@EnableAutoConfiguration
@Import({ ServiceConfig.class,DefaultRepositoryConfig.class })
public class ApplicationConfig {

    private static Log logger = LogFactory.getLog(ApplicationConfig.class);

    public static void main(String[] args) {
        SpringApplication.run(ApplicationConfig.class);
    }

    @Bean
    protected servletcontextlistener listener() {
        return new servletcontextlistener() {
            @Override
            public void contextInitialized(ServletContextEvent sce) {
                logger.info("ServletContext initialized");
            }

            @Override
            public void contextDestroyed(ServletContextEvent sce) {
                logger.info("ServletContext destroyed");
            }
        };
    }
}

UserController. java：

@RestController
@RequestMapping("/")
public class UserController {

    @Autowired
    UserService userService;

    @RequestMapping(method = RequestMethod.GET)
    public ResponseEntity<String> testMethod() {
        return new ResponseEntity<>("Success!",HttpStatus.OK);
    }
}

UserControllerTest. java：

RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = {ApplicationConfig.class})
public class UserControllerTest {
    @Autowired
    private WebApplicationContext webApplicationContext;
    private mockmvc mockmvc;

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

    @Test
    public void testMethod() throws Exception {
        this.mockmvc.perform(get("/")).andExpect(status().isOk());
    }
}

Is there anything basic I'm missing? I didn't provide my own MVC configuration, and I didn't encounter spring MVC dispatcher servlet, so I think spring boot will automatically configure Tomcat

Solution

The result is a problem with the component scan configuration Even if the @ componentscan annotation is used, the controller is in a separate package, so spring never includes it in the scheduler

Adding @ componentscan (basepackages = "com. My. Controller") solves my problem
