无法在春季启动中创建Bean

Question

I am getting this

Error creating the bean with name 'listsServiceImpl': Unsatisfied dependency expressed through field 'listRepo'

every time I run my project, I get this error.I started playing with spring boot following this

http://www.baeldung.com/spring-data-couchbase

ListRepository.java

package com.test.example.repo;   
import org.springframework.data.repository.CrudRepository; 
import com.test.example.entity.Lists;

public interface ListsRepository extends CrudRepository<Lists,String>{
  }

ListsService.java

package com.test.example.service; import com.test.example.entity.Lists;

public interface ListsService { 
   void create(Lists list);     boolean
   checkListName(String listName, String userId); 
}

ListsServiceImpl

package com.test.example.service;
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service;
import com.test.example.entity.Lists;
import com.test.example.repo.ListsRepository;

@Service 
public class ListsServiceImpl implements ListsService{

 @Autowired     
 private ListsRepository listRepo;

 @Override  
 public void create(Lists list) {       
         listRepo.save(list);   
 }

  @Override     
  public boolean checkListName(String listName, String userId) {        
      // TODO Auto-generated method stub        
     return false;  
    } 

}

Answer 1

add

@ComponentScan("com.test.example")

in your main application class.

Answer 2

只需将@EnableJpaRepositories批注添加到您的配置类。
