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

Question

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

Answer 1

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

@Service
public class FCSPAnalysisImpl implements FCSPAnalysis
{}

Answer 2

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.

Answer 3

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

Answer 4

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

Answer 5

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;

    //...

}

Answer 6

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;
