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 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

Exception e                   TODO  handle exception             log info e toString               finally               session close                      return null             and   public

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.

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  quot UserController Adapter Test quot    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

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

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

Add repository annotation before your DAO Implementation Class  example    Repository public class EmpDAOImpl extends BaseNamedParameterJdbcDaoSupportUAM  implements EmpDAO

I added  Service before impl class and the error is gone    Service public class FCSPAnalysisImpl implements FCSPAnalysis

I missed to add    Controller  userBo   into UserBoImpl class    The solution for this is adding this controller into Impl class

When you use  DataJpaTest you need to load classes using  Import explicitly  It wouldn t load you for auto

User · Answer

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

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  amp  1 in dispatcherServlet xml  Example     lt bean name  dataService  class  com app DataServiceImpl  gt   lt bean name  dataService  class  com app DataServiceController  gt     amp   we are trying to autowired by dataService name   Solution  we changed the bean name  amp  its solved

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

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  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
