I am working with spring boot tutorial from javabrains and everything was clear until putting CrudRepository inside project. Below you can find my main class:
package pl.springBootStarter.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class CourseApiDataApplication
{
public static void main(String args[])
{
SpringApplication.run(CourseApiDataApplication.class,args);
}
}
Service class:
package pl.springBootStarter.app.topic;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
@Service
public class TopicService
{
@Autowired
private TopicRepository topicRepository;
private List<Topic> topics = new ArrayList<>(Arrays.asList(
new Topic("spring","spring framework", "spring framework dectription"),
new Topic("sprin","spring framework", "spring framework dectription"),
new Topic("spri","spring framework", "spring framework dectription")));
public List<Topic> getAllTopics()
{
// return topics;
List<Topic> t = new ArrayList<Topic>();
topicRepository.findAll().forEach(t::add);
return t;
}
public Topic getTopic (String id)
{
return topics.stream().filter( t -> t.getId().equals(id)).findFirst().get();
}
public void addTopic(Topic topic) {
topicRepository.save(topic);
}
public void updateTopic(Topic topic, String id)
{
topics.set(topics.indexOf(topics.stream().filter(t-> t.getId().equals(id)).findFirst().get()), topic);
}
public void deleteTopic(String id)
{
topics.remove(topics.stream().filter(t -> t.getId().equals(id)).findFirst().get());
}
}
And Repository interface:
package pl.springBootStarter.app.topic;
import org.springframework.data.repository.CrudRepository;
public interface TopicRepository extends CrudRepository<Topic,String>
{
}
When I run the app there is a problem with injection of TopicRepository into topicRepository field in TopicService class. I get following error:
Error starting ApplicationContext. To display the conditions report re- run your application with 'debug' enabled.

Description:
Field topicRepository in pl.springBootStarter.app.topic.TopicService required a bean of type 'pl.springBootStarter.app.topic.TopicRepository' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
What could be the reason that Spring cannot do the autowiring?
TopicRepositoryclass and registering as a bean?? – Cloison
