尝试从端点请求响应时模型映射器出现问题

如何解决尝试从端点请求响应时模型映射器出现问题

Holla开发人员，我使用Maven在Spring-Boot的基础上开发了这个应用程序，而且我遇到了一个奇怪的错误，从未发生过。每当我从Swagger发出请求时，都会收到响应

 Converter org.modelmapper.internal.converter.NumberConverter@471e4a3f failed to convert com.apprestaurant.AppRestaurant.entity.Restaurant to java.lang.Long.
Caused by: org.modelmapper.MappingException: ModelMapper mapping errors:

1) Error mapping
 Restaurant [id=1,name=Gourmet African Food,restaurantDescription=The best of African Food,restaurantAddress=Badalona,Latrilla,7,6,restaurantImage=https://tul.imgix.net/content/article/Glamp_Cocktail_Bar-32.jpg,bookings=[com.apprestaurant.AppRestaurant.entity.Booking@c576b58],boards=[com.apprestaurant.AppRestaurant.entity.Board@90c702d,com.apprestaurant.AppRestaurant.entity.Board@67094136,com.apprestaurant.AppRestaurant.entity.Board@42fcfcbb,com.apprestaurant.AppRestaurant.entity.Board@52511965],turns=[com.apprestaurant.AppRestaurant.entity.Turn@187c981e,com.apprestaurant.AppRestaurant.entity.Turn@4bea963c,com.apprestaurant.AppRestaurant.entity.Turn@7ad329e1,com.apprestaurant.AppRestaurant.entity.Turn@7e8e4b8]] to java.lang.Long

我确实在Pom.xml中检查了从模型映射器的导入

        <dependency>
            <groupId>org.modelmapper</groupId>
            <artifactId>modelmapper</artifactId>
            <version>2.3.8</version>
        </dependency>

尽管可以正常运行该应用程序，但任何时候我只要调用引用获取数据的任何端点即可从我的一个实体中发生这种情况。

就像在服务实现中一样，在我的服务上同时引用了模型映射器：

FOR THE SERVICE

package com.apprestaurant.AppRestaurant.services;

import java.util.List;

import com.apprestaurant.AppRestaurant.exceptions.AppException;
import com.apprestaurant.AppRestaurant.jsons.RestaurantJson;

public interface RestaurantService {


    List<RestaurantJson>getAllRestaurants()throws AppException;
}

FOR THE SERVICE IMPLEMENTATION
package com.apprestaurant.AppRestaurant.services.implementation;

import java.util.List;
import java.util.stream.Collectors;

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

import com.apprestaurant.AppRestaurant.entity.Restaurant;
import com.apprestaurant.AppRestaurant.exceptions.AppException;
import com.apprestaurant.AppRestaurant.exceptions.NotFoundException;
import com.apprestaurant.AppRestaurant.jsons.RestaurantJson;
import com.apprestaurant.AppRestaurant.repositories.RestaurantRepository;
import com.apprestaurant.AppRestaurant.services.RestaurantService;


@Service
public class RestaurantServiceImpl implements RestaurantService {

    @Autowired
    RestaurantRepository restaurantRepository;
    
    public static final ModelMapper modelMapper = new ModelMapper();

    
    public List<RestaurantJson> getAllRestaurants() throws AppException {
        final List<Restaurant> restaurant = restaurantRepository.findAll();
        return restaurant.stream().map(service -> modelMapper.map(service,RestaurantJson.class))
                .collect(Collectors.toList());
    }

    }

我的存储库调用该方法将是

package com.apprestaurant.AppRestaurant.repositories;

import java.util.List;
import java.util.Optional;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import com.apprestaurant.AppRestaurant.entity.Restaurant;

@Repository
public interface RestaurantRepository extends JpaRepository<Restaurant,Long> {
    public List<Restaurant> findAll();
}

然后建立端点连接的控制器就这样建立了：

package com.apprestaurant.AppRestaurant.coontrollers;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;
import com.apprestaurant.AppRestaurant.exceptions.AppException;
import com.apprestaurant.AppRestaurant.jsons.RestaurantJson;
import com.apprestaurant.AppRestaurant.response.BookingRestaurantResponse;
import com.apprestaurant.AppRestaurant.services.RestaurantService;

@RestController
@CrossOrigin(origins = "http://localhost:4200")
@RequestMapping(path = "/app-restaurant/version1")
public class RestaurantController {

    @Autowired
    RestaurantService restaurantService;

        @ResponseStatus(HttpStatus.OK)
    @RequestMapping(value = "/restaurant/all",method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_VALUE)
    public BookingRestaurantResponse<List<RestaurantJson>> getAllRestaurantsList() throws AppException {
        return new BookingRestaurantResponse<>("Success",String.valueOf(HttpStatus.OK),"OK",restaurantService.getAllRestaurants());
    };
}

在寻找解决此问题的方法时，我确实尝试实现了其他开发人员的工作，并且在我的环境变量中设置了系统变量a

MAVEN_OPTS= -Xmx1024m -XX:MaxPermSize=128m

但是最终没用。

知道为什么会发生这种情况吗？

PD：我知道已经在这里扩展了暴露的代码，但是我认为有必要，您还可以看到我的实体，以及我将其附加如下的json原因：
