为啥一直报autowired dependencies failed，求解啊。各位大侠。。

Question

**就是一个简单注入问题，但是就不知道为啥报错，也不是缺包de问题，
哪位大侠解惑一下，多谢**

代码部分：
@Service
public class EmployeeService {

    @Autowired
    private EmployeeRepository employeeRepository;
    
    @Transactional(readOnly=true)
    public Page<Employee> getPage(int pageNo,int pageSize){
        PageRequest pageable=new PageRequest(pageNo-1, pageSize);
        return employeeRepository.findAll(pageable);
    }
}

public interface EmployeeRepository extends JpaRepository<Employee, Integer> {

}

Answer 1

public interface EmployeeRepository extends JpaRepository<Employee, Integer> {

}

这里加上注解`@Repository`，不然这个bean不会被Spring管理，自然无法注入
