JUnit 4 Tests don't work with Spring 3, @Inject, @Service annotations

[infinity2heaven]

Most Tests and examples include an xml config file. I have a project setup mostly with annotations and base spring 3 config. I can't get the tests to run since I get an error that no matching bean of type is found:


Caused by:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [xxx.service.ProfileService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@javax.inject.Inject()}

Testclass

@RunWith
(SpringJUnit4ClassRunner.class)
@ContextConfiguration (locations = { 

  "classpath*:applicationContext-core.xml",
  "classpath*:applicationContext-mail.xml",
  "classpath*:applicationContext-security.xml" })
@TransactionConfiguration
@Transactional
public class ProfileServiceTest {

 
  @Inject
   private ProfileService profileService;
 
  @Test
   publicvoid testSave() {
       List<BMSProfile> list = profileService.findAccounts();
       assertEquals(list.size(), 1);
   }
}

As you can see, it's a straight forward Spring app using JSR330 injections and <context:annotation-config /> and <context:component-scan/> is setup in spring-core as well. It doesn't make a difference if @Autowired is used instead of @Inject.

Also, the config files are in the classpath while junit tests are running.

I got this working in 2.5x in my earlier projects. What am I missing here?

I assume that ProvileServiceImpl is in package xxx? What does your JUnit test look like? Did you ensure to add the @ContextConfiguration with the appropriate xml file locations? Does it work if you remove Spring Security (if so in the future it might be a better question for one of the other Spring forums)? If you make the xml invalid do you get an error when running the test (ensures you are loading the xml)?

[infinity2heaven]

Fixed now. Turned out to be yet another classpath issue. Apparently, Spring didn't error on file not found earlier. I had to add spring/applicationContext-*.xml in the @ContextConfiguration
