无法使用Java注释跨各种类对TestNG使用spring依赖项注入（JSR 330标准注释）

Question

I have a service which I am trying to inject across various classes in my tests but I am getting its instance as null.

My config interface:

MyService.java

public interface MyService {

    public String getHostUri();

}

My implementation class of this interface: MyServiceImpl.java

public class MyServiceImpl implements MyService {

    private static final String BASE_HOST_URI_CONFIG = "localhost:4444";

    @Override
    public String getHostUri() {
        return BASE_HOST_URI_CONFIG;
    }

My Spring configuration class with the bean:

@Configuration

public class AutomationSpringConfig {

    @Bean
    public MyService getMyService(){
        return new MyServiceImpl();
    }

}

My testNG class:

@ContextConfiguration(classes=AutomationSpringConfig.class ,loader =AnnotationConfigContextLoader.class)

public class BasicAutomatedTest extends AbstractTestNGSpringContextTests {

    private static final Logger LOGGER = Logger.getLogger(BasicAutomatedTest.class);

    @Inject
    private MyService myService;


    @Test
    public void basicTest {
        Setup setup = new Setup();
        LOGGER.info(myService.getHostUri());
        LOGGER.info(setup.myService.getHostUri());

    }
}

My helper class in which I am not able to get the injection:

public class Setup {

  @Inject

  public MyService myService;

}

So when I try to get the hostUri via the setup object in the BasicAutomatedTest's basicTest method I get a NullPointerException. So I am not able to inject the MyService bean in the Setup class.

In order to use annotations you need to specify that behaviour in your beans XML configuration file. Something like this:

<context:component-scan base-package="your.base.package"/>
<context:annotation-config/>

Hope it helps!
