这是我的控制人：

@RestController
@RequestMapping(value="vendors")
public class VendorController {


    @Autowired(required=true)
    private VendorServiceInterface vensorinterface;

    protected final Logger log = LoggerFactory.getLogger(this.getClass());

    @RequestMapping(value = "/vendor/add", method = RequestMethod.POST)
    public ModelAndView registreVendor(@RequestBody Vendor vendor)
    {
    Vendor v=vendor;
        log.info("vendor controller called"+vendor.getBussinessName());
    vendor= vensorinterface.registerVendor(vendor);
    return new ModelAndView("hello","vendor",v);
    }

这是VendorServiceInterface：

public interface VendorServiceInterface {

    Vendor registerVendor(Vendor vendor);

}

这是实现类：

@Service
public class VendorSerInterfaceImplement implements VendorServiceInterface {

    @Autowired(required=true)
    private VendorDaoInterface vendordaointerface;

    public Vendor registerVendor(Vendor vendor) {

        return vendordaointerface.registerVendor(vendor);
    }

这是dao接口和实现类：

public interface VendorDaoInterface {

    Vendor registerVendor(Vendor vendor);

}

这是dao的实现：

@Transactional
public class VendorIntefaceImplement implements VendorDaoInterface {

    @Autowired
    private HibernateTemplate hibernatetemplate;


    public Vendor registerVendor(Vendor vendor) {
    Session session=hibernatetemplate.getSessionFactory().getCurrentSession();
    session.beginTransaction();

    session.save(vendor);
    System.out.println("VEndor saved");
    session.close();


        return vendor;
    }

这是db-config：

Answer 1

No qualifying bean of type 'com.WeddinG.Vendor.Dao.VendorDaoInterface'

您指定了要Spring的容器将VendorIntefaceImplement提取为bean的任何位置。

实际上是

@Transactional
public class VendorIntefaceImplement implements VendorDaoInterface {
   ...
}

不定义bean，但是可以：

@Service
@Transactional
public class VendorIntefaceImplement implements VendorDaoInterface {
   ...
}

Answer 2

如果您使用的是 Open-Feign，请禁用 Netflix-Ribbon 将解决问题：

spring:
  cloud:
      loadbalancer:
        ribbon:
          enabled: false

创建名称为'vendorController'的bean时出错：通过字段'vensorinterface'表示的不满意的依赖关系；
