Unsatisfied dependency expressed through field 'dashboardService'; expected at least 1 bean which qualifies as autowire candidate

Question

I know this question has been asked so many times but I'm really having trouble to pick up the right solution. I have tried so many stuffs by seeing those questions but no one seems to fit my case.

The full log error is the following:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2018-09-20 12:28:25.613 ERROR 10152 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   :

APPLICATION FAILED TO START

Description:

Field dashboardService in com.timmi.springBoot.controllers.RestEndPoints required a bean of type 'com.timmi.springBoot.service.DashboardService' that could not be found.


Action:

Consider defining a bean of type 'com.timmi.springBoot.service.DashboardService' in your configuration.

Here's my current implementation:

SpringBootApplication:

@SpringBootApplication
@EnableJpaRepositories(basePackages="com.timmi.springBoot.repositories")
@EntityScan(basePackages="com.timmi.springBoot.entities")
@EnableAutoConfiguration
@ComponentScan(basePackages="com.timmi.springBoot.service")
public class Application extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // TODO Auto-generated method stub
        return super.configure(builder);
    }
}

RestController:

@RestController
@RequestMapping("/app")
public class RestEndPoints {

    @Value("${default.course.name}")
    private String cName;

    @Value("${default.course.chapterCount}")
    private int chaptersCount;

    @Autowired
    private CourseConfiguration courseConfiguration;

    @Autowired
    private DashboardService dashboardService;

    @RequestMapping("/employees")
    public List<EmployeeInformation> getAllEmpl(){

        return dashboardService.getAllEmployee();

    }
}

DashboardService interface:

public interface DashboardService{

    List<CompanyRevenue> getTodayRevenueDash();

    List<ProductCategory> getBestCategory();

    List<OrderRecieved> getAllOrderRecieved();

    List<OrderCollectionStatus> getOrderCollection();

    List<EmployeeInformation> getAllEmployee();

    void addEmployee(EmployeeInformation employeeInformation);

    EmployeeInformation updateEmployee(EmployeeInformation employeeInformation);

    void deleteEmployee(EmployeeInformation employeeInformation);

}

class service :

@Service
public class DashboardServiceImpl implements DashboardService{

    @Autowired
    private CompanyRevenueRepository companyRevenueRepository;

    @Autowired
    private EmployeeInformationRepository employeeInformationRepository;

    @Autowired
    private OrderCollectionStatusRepository OrderCollectionStatusRepository;

    @Autowired
    private OrderRecievedRepository orderRecievedRepository;

    @Autowired
    private ProductCategoryRepository productCategoryRepository;

    @Override
    public List<CompanyRevenue> getTodayRevenueDash() {
        return companyRevenueRepository.findAll();
    }

    @Override
    public List<ProductCategory> getBestCategory() {
        return productCategoryRepository.findByBestCategory(true);
    }

    @Override
    public List<OrderRecieved> getAllOrderRecieved() {
        return orderRecievedRepository.findAll();
    }

    @Override
    public List<OrderCollectionStatus> getOrderCollection() {

    }

    @Override
    public List<EmployeeInformation> getAllEmployee() {

Can you try using `@ComponentScan` in your `Application.java`? — robot_alien, Sep 20 '18 at 12:46

@ComponentScan solves the issue, but it gives another problem using postman:{ "timestamp": "2018-09-20T12:58:10.955+0000", "status": 404, "error": "Not Found", "message": "No message available", "path": "/app/employees" } — ABDELJALIL TIMMI, Sep 20 '18 at 12:58
To match this path, try adding a `@RequestMapping("/app")` annotation directly on your `RestEndPoints`class. — Arnaud, Sep 20 '18 at 13:04
hi, can you now update your post with the code modifications specifically in your Application.java, so that we can find out what is causing the problem? — robot_alien, Sep 20 '18 at 13:35
Doing these modifications, the only issue i get is: { "timestamp": "2018-09-20T13:45:20.302+0000", "status": 404, "error": "Not Found", "message": "No message available", "path": "/app/employees" } — ABDELJALIL TIMMI, Sep 20 '18 at 13:44
Are your application & controller classes sitting in different packages? asking because @ComponentScan only scans for components in the same package.. — robot_alien, Sep 20 '18 at 14:04
-src/main/java --com.timmi.springBoot.controllers Application.java RestEndPoints.java --com.timmi.springBoot.service DashboardService.java --com.timmi.springBoot.service.impl DashboardServiceImpl.java — ABDELJALIL TIMMI, Sep 20 '18 at 14:39
Application and RestEndPoints are in the same package, DashboardService and DashboardServiceImpl are in two others package — ABDELJALIL TIMMI, Sep 21 '18 at 10:51
Thank you guys, i solved the issue by moving the Application to the root package com.timmi.springBoot; best regards — ABDELJALIL TIMMI, Sep 21 '18 at 11:33

Remove @Repository and @Qualifier from your DashboardService and @Component from DashboardServiceImpl

And please get familiar with those annotations: What's the difference between @Component, @Repository & @Service annotations in Spring?

So the solution is to put the application class in root package, so here we don't need to make ComponantScan annotation

Yes, that worked because *"The SpringBootApplication annotation is equivalent to using Configuration, EnableAutoConfiguration and ComponentScan with their default attributes"*- excerpt from **Spring Official Documentation.** – robot_alien Sep 21 '18 at 12:38
