SessionFactory bean Initialised in Junit test but not in @SprinBootApplication

Question

I have a SpringBoot application which has hibernate integrated to it. I have wired in hibernate properties using Spring. When I use the sessionFactory in a Junit test I can do all the CRUD Operations but when I run the SpringBootApplication i.e., when I run the Main class which has @SpringBootApplication in it; it ends up getting an

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} exception.

Any idea on how to solve this?

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class GreetingRepositoryDAOTest {

    @Resource
    private BaseRepository greetingRepositoryImpl;

    @Test
    public void test() {
        System.out.println(((Greeting) greetingRepositoryImpl.findOne(1L)).getText());
        Greeting gr = new Greeting();
        gr.setText("Third Text");
        greetingRepositoryImpl.save(gr);
    }
}

@RestController
@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    @RequestMapping("/")
    String home() {
        return "Hello World!";
    }

}

@Repository
public class BaseDAO {

    @Autowired
    private SessionFactory sessionFactory;

    public Criteria createCriteria(Class<?> clazz, String alias) {
        return currentSession().createCriteria(clazz, alias);
    }

    public Session currentSession() {
        return sessionFactory.getCurrentSession();
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

Spring Boot by default does not load beans applicationContext.xml. You can do it by annotating your Application class additionally with:

@ImportResource("classpath:applicationContext.xml")

This will add BaseDAO to Spring Boot application context, but it looks that you have more problems in your code:

• there is no need for creating PropertyPlaceholder for application.properties - it's being loaded by Spring Boot by default
• have a look at Spring Data JPA and how does it work with Spring Boot - it may simplify your Hibernate configuration (I see you have another hibernateContext.xml that most likely is not needed).
• consider dropping xml beans configuration in favour of @Configuration classes.
