[java] No found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations:

I am trying to write a SOAP service using Spring, however I receive a Dependency Injection issue. I'm having problems using @Autowired through the Service like this:

    public interface UserDao {
    User getUser(String username);
}

Implementation for Dao as below:

  @Controller("userDao")
    public class UserDaoImpl implements UserDao {
    private static Log log = LogFactory.getLog(UserDaoImpl.class);

    @Autowired
    @Qualifier("sessionFactory")
    private LocalSessionFactoryBean sessionFactory;

    @Override
    public User getUser(String username) {
        Session session = sessionFactory.getObject().openSession();
        // Criteria query = session.createCriteria(Student.class);
        Query query = session
                .createQuery("from User where username = :username");
        query.setParameter("username", username);
        try {
            System.out.println("\n Load Student by ID query is running...");
            /*
             * query.add(Restrictions.like("id", "%" + id + "%",
             * MatchMode.ANYWHERE)); return (Student) query.list();
             */
            return (User) query.uniqueResult();
        } catch (Exception e) {
            // TODO: handle exception
            log.info(e.toString());
        } finally {
            session.close();
        }
        return null;
    }

}

and

public interface UserBo {
    User loadUser(String username);
}

and

public class UserBoImpl implements UserBo {
    @Autowired
    private UserDao userDao;

    @Override
    public User loadUser(String username) {
        // TODO Auto-generated method stub
        return userDao.getUser(username);
    }

}


@WebService
@Component
public class UserService {

    @Autowired
    private UserBo userBo;

    @WebMethod(operationName = "say")
    public String sayHello(String name) {
        return ("Hello Java to " + name);
    }

    @WebMethod(operationName = "getUser")
    public User getUser(String username) {
        return userBo.loadUser(username);
    }
}

You seems to be missing implementation for interface UserDao. If you look at the exception closely it says

No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency:

The way @Autowired works is that it would automatically look for implementation of a dependency you inject via an interface. In this case since there is no valid implementation of interface UserDao you get the error.Ensure you have a valid implementation for this class and your error should go.

Hope that helps.

In my case I had to move the @Service annotation from the interface to the implementation class.

Add the annotation @Repository to the implementation of UserDaoImpl

@Repository
public class UserDaoImpl implements UserDao {
    private static Log log = LogFactory.getLog(UserDaoImpl.class);

    @Autowired
    @Qualifier("sessionFactory")
    private LocalSessionFactoryBean sessionFactory;

    //...

}

In my case, the application context is not loaded because I add @DataJpaTest annotation. When I change it to @SpringBootTest it works.

@DataJpaTest only loads the JPA part of a Spring Boot application. In the JavaDoc:

Annotation that can be used in combination with @RunWith(SpringRunner.class) for a typical JPA test. Can be used when a test focuses only on JPA components. Using this annotation will disable full auto-configuration and instead apply only configuration relevant to JPA tests.

By default, tests annotated with @DataJpaTest will use an embedded in-memory database (replacing any explicit or usually auto-configured DataSource). The @AutoConfigureTestDatabase annotation can be used to override these settings. If you are looking to load your full application configuration, but use an embedded database, you should consider @SpringBootTest combined with @AutoConfigureTestDatabase rather than this annotation.

When you use @DataJpaTest you need to load classes using @Import explicitly. It wouldn't load you for auto.

Look at the exception:

No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency

This means that there's no bean available to fulfill that dependency. Yes, you have an implementation of the interface, but you haven't created a bean for that implementation. You have two options:

• Annotate UserDaoImpl with @Component or @Repository, and let the component scan do the work for you, exactly as you have done with UserService.
• Add the bean manually to your xml file, the same you have done with UserBoImpl.

Remember that if you create the bean explicitly you need to put the definition before the component scan. In this case the order is important.

I missed to add

@Controller("userBo") into UserBoImpl class.

The solution for this is adding this controller into Impl class.

We face this issue but had different reason, here is the reason:

In our project found multiple bean entry with same bean name. 1 in applicationcontext.xml & 1 in dispatcherServlet.xml

Example:

<bean name="dataService" class="com.app.DataServiceImpl">
<bean name="dataService" class="com.app.DataServiceController">

& we are trying to autowired by dataService name.

Solution: we changed the bean name & its solved.

In my case, I had the following structure of a project:

When I was running the test, I kept receiving problems with auro-wiring both facade and kafka attributes - error came back with information about missing instances, even though the test and the API classes reside in the very same package. Apparently those were not scanned.

What actually helped was adding @Import annotation bringing the missing classes to Spring classpath and making them being instantiated.

I just solved this error happening in my tests.

Just make sure your test class has all dependencies in the attributes of the class being tested annotated with @MockBean so SpringBoot test context can wire your classes correctly.

Only if you are testing controller: you need also class annotations to load the Controller context propertly.

Check it out:

@DisplayName("UserController Adapter Test")
@WebMvcTest(UserController.class)
@AutoConfigureMockMvc(addFilters = false)
@Import(TestConfig.class)
public class UserControllerTest {

@Autowired
private MockMvc mockMvc;

@Autowired
private ObjectMapper objectMapper;

@MockBean
private CreateUserCommand createUserCommand;

@MockBean
private GetUserListQuery getUserListQuery;

@MockBean
private GetUserQuery getUserQuery;

I added @Service before impl class and the error is gone.

@Service
public class FCSPAnalysisImpl implements FCSPAnalysis
{}

Add repository annotation before your DAO Implementation Class. example:

@Repository
public class EmpDAOImpl extends BaseNamedParameterJdbcDaoSupportUAM 
implements EmpDAO{ 
}

Could me multiple reason for this. But you want might forget to add as @Bean for component which you have did @Autowired.

In my case, i have forgot to decorate with @Bean which causing this issue.
