Spring启动 MVC - 无法自动连接服务类中的存储库

Question

我已经用@Autowired注释为相应的存储库定义了服务类

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class StoreService {

    @Autowired
    private StoreRepository repository;

存储库接口定义为从JpaReepository扩展

import org.springframework.data.jpa.repository.JpaRepository;

public interface StoreRepository extends JpaRepository<Store, String> {
}

应用程序自动编译服务类

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.*;

@RestController
public class StoreController {

    @Autowired
    private StoreService service;

运行时，我得到以下错误

***************************
APPLICATION FAILED TO START
***************************

Description:

Field repository in com.mypackage.service.StoreService required a bean of type 'com.mypackage.respository.StoreRepository' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.mypackage.respository.StoreRepository' in your configuration.

Answer 1

只需将@Repository注释添加到StoreRepository中，它就会正常工作。

以下是Spring识别的最常用的注释，可以用于自动连接，而无需显式地将其声明为bean：

Answer 2

我认为您应该用@repository注释您的存储库，然后它将由Spring Framework自动启用。

@Repository
public interface StoreRepository extends JpaRepository<Store, String> {
}
