Question

我正在尝试从服务实现类中获取@autowire存储库引用，但仍然出现未找到bean错误

我已经尝试在父级中移动App.java文件

App.java

root.clipboard_clear()
root.clipboard_append(entry.get())

VehicleService.java

package com.trucker;
import org.springframework.context.ApplicationContext;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App
{
    public static void main( String[] args ){
        ApplicationContext applicationContext = SpringApplication.run(App.class,args);

    }
}

VehicleRepositoryInterface.java

package com.trucker.service;

import com.trucker.entity.Vehicle;
import com.trucker.repository.VehicleRepositoryInterface;

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

@Service
public class VehicleService implements VehicleServiceI {

    @Autowired
    VehicleRepositoryInterface vehicleRepository;

    @Override
    public Vehicle addVehicles(Vehicle vehicle) {
        System.out.println(vehicle);
        return vehicleRepository.save(vehicle);
    }

}

VehicleController.java

package com.trucker.repository;

import com.trucker.entity.Vehicle;
import org.springframework.context.annotation.Bean;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

public interface VehicleRepositoryInterface extends CrudRepository<Vehicle,String> {

}

Vehicle.java

package com.trucker.controller;

        System.out.println("************IN THE CONTROLLER************"+vehicle);
        vehicleService.addVehicles(vehicle);
        return "";

Answer 1

看看这篇帖子，它有明确的答案

Spring boot autowiring an interface with multiple implementations

或

Spring autowire interface

Field VehicleRepository需要找不到的..VehicleInterface类型的Bean
