Spring Autowire error expected at least 1 bean which qualifies as autowire candidate for this dependency

Question

I am trying to Autowire beans in this project but keep getting error

expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)"

Java:

@Controller
@RequestMapping(value="/Home")
public class HomeController {

@Autowired
private Personrepo personRepo;

@RequestMapping(method=RequestMethod.GET)
public String showForm(ModelMap model){
    List<Person> persons = personRepo.getAll();
    model.addAttribute("persons", persons);
    Person person = new Person();
    model.addAttribute("person", person);
    return "home";
}


@RequestMapping(value="/add", method=RequestMethod.POST)
public ModelAndView add(@ModelAttribute(value="person") Person person,BindingResult result){

    ModelAndView mv = new ModelAndView("home");
    if(!result.hasErrors()){
        personRepo.add(person);
        person = new Person();
        mv.addObject("person", person);
    }
    mv.addObject("persons", personRepo.getAll());
    return mv;
}


@RequestMapping(value="/edit", method=RequestMethod.POST)
public ModelAndView edit(@ModelAttribute(value="person") Person person,BindingResult result){

    ModelAndView mv = new ModelAndView("home");
    if(!result.hasErrors()){
        personRepo.edit(person);
        person = new Person();

        mv.addObject("person", person);
    }
    mv.addObject("persons", personRepo.getAll());
    return mv;
}
@RequestMapping(value="/delete", method=RequestMethod.POST)
public ModelAndView update(@ModelAttribute(value="person") Person person,BindingResult result){
    ModelAndView mv = new ModelAndView("home");
    if(!result.hasErrors()){
    personRepo.delete(person.getId());

        //personRepo.delete(person);
        person = new Person();

        mv.addObject("person", person);
    }
    mv.addObject("persons", personRepo.getAll());
    return mv;
}

Now I am not getting datasource bean error but only the error not find autowire bean. When I tried to add com.app.service.PersonService com.app.r.Personrepo. in application context.xml

It gives me http not found error uri

Answer 1

if you've tried all the suggestions but still not work, then here's a way that last to do is to delete the project files in server ,for example i'm using tomcat, then go into the webappsdir and workdir, delete the corresponding project file. Be cautious when deleting.

i solved the same issue by this, so i'm considering its cause by the project cache even though cleared the projectandserverin the IDE.Wish it can help :)

Answer 2

I was having same problem. I resolved this after properly naming the the package name in the following code <context:component-scan base-package="com.mysweethome"></context:component-scan>

Answer 3

Spent much of my time with this! My bad! Later found that the class on which I declared the annotation Service or Component was of type abstract. Had enabled debug logs on Springframework but no hint was received. Please check if the class if of abstract type. If then, the basic rule applied, can't instantiate an abstract class.
