spring messagesource while testing

Question

i have message source defined in my java config as :

@Bean(name = "messageSource")
public MessageSource messageSource() {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    messageSource.setBasenames(
            "/i18n/ir/kia/industry/webapp/entity",
            "/i18n/ir/kia/industry/webapp/formErrors",
            "/i18n/ir/kia/industry/webapp/frontend",
            "/i18n/ir/kia/industry/webapp/frontendPages");
    return messageSource;
}

it works fine when using site and messages are displayed correctly, but when trying to write spring test with :

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestContext.class, SpringMVC.class})
@WebAppConfiguration
public abstract class AbstractTestClass {
  protected MockMvc mockMvc;
  @Autowired
  private WebApplicationContext webApplicationContext;

  @Before
  public void setUp() throws Exception {
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
  }
}

and a test class that simply extends it, i get error Can't find bundle for base name /i18n/ir/kia/industry/webapp/entity.

it works fine when starting tomcat and using message source in jsp files, but no luck when testing it. i have tried moving i18n folder under WEB-INF but it did not help it neither.

the target folder looks like this and please do not tell me add i18n folder to target resources ...

Solution

i managed to solve the problem by removing the message source base names using spring profile feature. i changed the message source part to :

@Bean(name = "messageSource")
@Profile(value = {"dev","prod"})
public MessageSource messageSource() {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    messageSource.setBasenames(
            "/i18n/ir/kia/industry/webapp/entity",
            "/i18n/ir/kia/industry/webapp/formErrors",
            "/i18n/ir/kia/industry/webapp/frontend",
            "/i18n/ir/kia/industry/webapp/frontendPages");
    messageSource.setCacheSeconds(5);
    return messageSource;
}

@Bean(name = "messageSource")
@Profile("test")
public MessageSource testMessageSource() {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    return messageSource;
}

and add test profile to my test unit with

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestContext.class, SpringMVC.class})
@WebAppConfiguration
@ActiveProfiles("test")
public abstract class AbstractTestClass {

that when i was able to run my tests, but that is a way around for solving problem. i'm still confused for what was the reason of error in the first place. it that some sort of bug? or i'm doing something wrong?
