java.lang.IllegalArgumentException：不是 Spring Boot

Question

我的代码中出现以下错误

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为“locationServiceImpl”的 bean 时出错：通过方法“setLocationrepo”参数 0 表示的不满意依赖；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名为“locationRepository”的 bean 时出错：调用 init 方法失败；嵌套异常是 java.lang.IllegalArgumentException: Not a managed type: class com.logan.location.entities.Location

这是我的存储库界面

package com.logan.location.repos;

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

import org.springframework.stereotype.Repository;

import com.logan.location.entities.Location;

@Repository

public interface LocationRepository extends JpaRepository<Location, Integer> {

}

这是我的服务接口

package com.logan.location.service;

import java.util.List;

import org.springframework.stereotype.Service;

import com.logan.location.entities.Location;

@Service

public interface LocationService {

    Location saveLocation(Location location);

    Location updateLocation(Location location);

    void deleteLocation(Location location);

    Location getLocationById(int id);

    List<Location> getAllLocations();

}

这是我的 serviceImpl

package com.logan.location.service;

import java.util.List;

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

import org.springframework.stereotype.Service;

import com.logan.location.entities.Location;

import com.logan.location.repos.LocationRepository;

@Service

public class LocationServiceImpl implements LocationService {

    private LocationRepository locationrepo;

    @Autowired

    public void setLocationrepo(LocationRepository locationrepo) {

        this.locationrepo = locationrepo;

    }

    public Location saveLocation(Location location) {

        // TODO Auto-generated method stub

        return locationrepo.save(location);

    }

    public Location updateLocation(Location location) {

        // TODO Auto-generated method stub

        return locationrepo.save(location);

    }

它显示我的位置实体类是非托管的，我尝试了各种答案但它不起作用，有什么帮助吗？
