UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency

Question

I'm new to spring MVC. I'm facing UnsatisfiedDependencyException. I have added stereotype annotations but still I'm facing same issue.

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [com.demo.app.service.UserService]: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} looking positive replay.

UserController:

@CrossOrigin
@RestController
public class UserController {

@Autowired(required=true)
private UserService userService;

@RequestMapping(value = { "/userSave" },consumes = {"multipart/form-data"}, method = RequestMethod.POST)
@ResponseBody
public String saveUserDetails(@RequestPart(value="file",required=false) MultipartFile file,
        @RequestPart("user")User user,
        HttpSession session, HttpServletRequest request,
        HttpServletResponse response){
        System.out.println("data reached...!");
        String result=userService.saveUserData(user,session);
        return result;

}

}

UserService:

public interface UserService {
     public String saveUserData(User user,HttpSession session);
}

UserServiceImpl:

@Service("userService")
public class UserServiceImpl implements UserService{

@Autowired
UserRepository userRepository;

public String saveUserData(User user,HttpSession session){
    String  output;
    Date regDate=new Date();
    user.setRegDate(regDate);
    output= userRepository.saveUserData(user);
    return output;
}

}

UserRepository:

@Component
@Transactional
public class UserRepository  extends BaseRepository{

@Autowired
protected SessionFactory sessionFactory;


public String saveUserData(User user) {

    final Session session = (Session) getSessionFactory();
    try {
        session.beginTransaction();
        Query query=session.createQuery("UPDATE User set user_Name =:userName,"
                + "reg_Date =:regDate,img_Id=:imgId");
        query.setParameter("userName", user.getUserName());
        query.setParameter("regDate", user.getRegDate());
        query.setParameter("imgId", user.getImgId());
        query.setParameter("emailId", user.getImgId());
        session.save(user);
        session.getTransaction().commit();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

}

Please help me,

Thank you

Answer 1

Check all the following points :

1 - @Entity added to all entities .

2 - @Service added to all DAOs or any other components .

3 - @RestController added to all Controllers .

My Error was not added @Entity on my entity .

Answer 2

I too had this issue.

In my case I thought it was the Maven dependencies and updated them and got all my Java files as error.

Finally, after updating all the Maven dependencies and added this

<dependency>
  <groupId>org.glassfish.jaxb</groupId>
  <artifactId>jaxb-runtime</artifactId>
  <version>2.3.1</version>
</dependency>

That works for projects which are Java versions > 9 I was using OpenJDK 11 in my project. Thanks. Hope it helps.

Happy Coding. 🖖🏼

Answer 3

My problem was that I didn't have @EnableWebSecurity in this class:

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        // add our users for in memory authentication

        User.UserBuilder users = User.withDefaultPasswordEncoder();

        auth.inMemoryAuthentication()
                .withUser(users.username("john").password("test123").roles("EMPLOYEE"))
                .withUser(users.username("mary").password("test123").roles("MANAGER"))
                .withUser(users.username("susan").password("test123").roles("ADMIN"));
    }



    @Override
    protected void configure(HttpSecurity http)  throws Exception {
        http.authorizeRequests().anyRequest().authenticated().and()
                .formLogin().loginPage("/showLoginPage")
                .loginProcessingUrl("/authenticateTheUser")
                .permitAll();
    }
}

Finally i resolved .spring dependency jar file versions are mismatched. all spring dependency versions are same.

     <dependencies>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>4.2.3.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.2.3.RELEASE</version>
</dependency>
<dependency>

Answer 5

"No qualifying bean found for dependency [com.demo.app.service.UserService]: expected at least 1 bean which qualifies as autowire candidate."

Above error means UserService bean were not created. Can you please check whether you've give the correct base package here.

Also can you please change annotation to UserRepository @Component to @Repository.

Answer 6

@service annotation use in service implementation, not in interface because interface is only mapping controller to actual service implementation and other logic only...

Answer 7

@Service("userService") should be near implementation not interface.
