No qualifying bean of type [services.ExportService] found for dependency

I get an error on a simple Spring project and I don't know the cause of this error -
No qualifying bean of type [services.ExportService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'helloController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [services.ExportService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Try using @Autowired and enabling .

But besides that, just so you know by Spring's best practice, there are 3 layers:

@Controller, @Service, @Repository.

@Controller is obviously the controller, @Repository would be your DAO classes, in this instance you name your class "Service", but in reality you're using it as a DAO class, so it should actually get a @Repository annotation. @Service layer is where you'll do your conversions, business logic, caching, etc.

You should mark your ExporterServiceImpl with @Service, by the docs

The Resource annotation marks a resource that is needed by the application.

and

If the annotation is applied to the component class, the annotation declares a resource that the application will look up at runtime.

so when used on a class-level it doesn't specify the class to be a Spring bean (hence your error), rather just defers the look-up of a target resource to runtime

UPDATE with respect to the comment

This is surely the issue with the code you've posted in the question. For what concerns not working after the changes, wouldn't know, but, will give you some pointers that are at least confusing.

You can consider to use @Autowire, you might check out the @Resource vs @Autowired, in short @Resource is not suppose to inject a dependency by type, but Spring enables this as a fallback. I would still advise to give @Autowired a try.

I also notice that you don't have the <mvc:annotation-driven/> in your mvc-dispatcher-servlet.xml, this is not causing your issue directly, but the handlers for controller mappings won't be created without it.

Finally, a suspicious, but not an important change is, you access your beans with a fully qualified name, e.g. services.ExporterService, and you initialize it to null. This should also not pose any problem, but its unconventional, you should simply add an import declaration and omit setting to null.
