reST (reStructuredText) Question

404 not found while testing spring boot rest api

I am trying to write tests on my applicatoin's rest api. I am using spring boot, jersey rest. For testing I am trying to use MockMvc, but for all GET requests I get 404 status code. I tried different ways to run it, but result is always the same. I think I am missing something, so, please, advise.

REST resource:

@Component
@Path("/v1/users")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Transactional(readOnly = true)
public class UserResource {
private final UserService userService;

@Inject
public UserResource(UserService userService) {
this.userService = userService;
}

@GET
public Collection<User> list() {
return userService.fetchAllUsers();
}
}


Application class:

@SpringBootApplication
@ComponentScan("com.glasierr.application")
@EnableJpaRepositories("com.glasierr.application.infrastructure.persistence.spring")
public class UserServiceApplication {
public static void main(String[] args) {
new SpringApplicationBuilder()
.sources(UserServiceApplication.class)
.run(args);
}
}


Jersey config:

@Configuration
@ApplicationPath("/api")
public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
packages("com.glasierr.application.resource");
}
}


Test properties snippet:

server:
port: 9999

database:
driverName: org.h2.Driver
url: jdbc:h2:mem:test;IGNORECASE=TRUE;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1
username: sa
password:
hibernateDialect: org.hibernate.dialect.H2Dialect
hibernateShowSql: true
hibernateHbm2ddl: update


Testing class:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(UserServiceApplication.class)
@WebIntegrationTest
public class UserResourceTest {

@InjectMocks
private UserResource userResource;

@Mock
private UserService userService;

@Autowired
private WebApplicationContext context;

private MockMvc mvc;

@Before
public void setUp() {
MockitoAnnotations.initMocks(this);

mvc = MockMvcBuilders
.webAppContextSetup(context)
.build();
}

@Test
public void test() throws Exception {
when(userService.fetchAllUsers()).thenReturn(Arrays.asList(new User("user1"), new User("user2")));

mvc.perform(get("/api/v1/users").accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
.andExpect(status().isOk());
}
}


Some console output:

Answer

Problem solved. I have included configurations in application class and it worked.

@SpringBootApplication
@Configuration  
@Import({JerseyConfig.class})
public class UserServiceApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder()
                .sources(UserServiceApplication.class)
                .run(args);
    }    
}
