不断收到错误“org.springframework.dao.InvalidDataAccessResourceUsageException：执行SQL时出现JDBC异常”

Question

我正在使用 springboot、maven 和 postgresql JDBC 创建一个简单的电影 api，但是每当我发出 http GET 请求时，都会出现此错误：

} 

我不明白为什么

我的控制器类：

package com.br.Idespair.MoviesAPIWithSQL.controller;

import com.br.Idespair.MoviesAPIWithSQL.model.Movie;
import com.br.Idespair.MoviesAPIWithSQL.service.MovieService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
import java.util.Optional;

@RestController
@RequestMapping("api/movies")
public class MovieController {

@Autowired
private MovieService movieService;

@GetMapping
public ResponseEntity<List<Movie>> getAllMovies(){
return new ResponseEntity<List<Movie>> 
(movieService.AllMovies(), HttpStatus.OK);
}
@GetMapping("/{imdbId}")
public ResponseEntity<Optional<Movie>> 
getSingleMovie(@PathVariable 
String imdbId){
return new ResponseEntity<Optional<Movie>> 
(movieService.singleMovie(imdbId),HttpStatus.OK);
}
}

我的服务等级：

package com.br.Idespair.MoviesAPIWithSQL.service;

import com.br.Idespair.MoviesAPIWithSQL.model.Movie;
import 
com.br.Idespair.MoviesAPIWithSQL.repository.IMovieRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Optional;

@Service
public class MovieService {

@Autowired
private IMovieRepository movieRepository;

public List<Movie> AllMovies(){
return movieRepository.findAll();
}

public Optional<Movie> singleMovie(String imdbId){
return movieRepository.findMovieByImdbId(imdbId);
}

}

我创建电影实例的模型类：

package com.br.Idespair.MoviesAPIWithSQL.model;

import jakarta.persistence.*;
;
import lombok.Data;
import org.springframework.data.annotation.Reference;


import java.util.List;
@Entity
@Data
@Table(name = "movies")
public class Movie {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private String imdbId;
private String title;
private String releaseDate;
private String trailerLink;
private String poster;
private List<String> genres;
private List<String> backdrops;
@OneToMany(mappedBy = "movie")
private List<Review> reviews;

public Movie(String imdbId, String title, String 
releaseDate, String trailerLink, String poster, List<String> 
genres, List<String> backdrops) {
                this.imdbId = imdbId;
                this.title = title;
                this.releaseDate = releaseDate;
                this.trailerLink = trailerLink;
                this.poster = poster;
                this.genres = genres;
                this.backdrops = backdrops;
        }
}

还有我的存储库类：

package com.br.Idespair.MoviesAPIWithSQL.repository;

import com.br.Idespair.MoviesAPIWithSQL.model.Movie;
import org.springframework.data.jpa.repository.JpaRepository;

import java.util.List;
import java.util.Optional;


public interface IMovieRepository extends 
JpaRepository<Movie,String> {

    Optional<Movie> findMovieByImdbId(String imdbId);

}

我尝试阅读错误消息，它说对象 imdb_id 有错误，它应该是 imdbId，但引用 imdbId 的所有对象都是这样编写的，并且我的任何类上都没有写 imdb_id 。

我使用 postman 处理 HTTP 请求，使用 postgres 处理数据库 我还没有在这个应用程序上使用过 docker。

Answer 1

错误消息提到“m1_0.imdb_id”列不存在，我认为发生错误是因为您的Java代码中的字段名称（

imdbId

）和相应的列名称（

imdb_id

）不匹配）在您的数据库中。您可以尝试添加以下行来解决此问题：

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "imdb_id") // Add this line
private String imdbId;

通过将

@Column(name="imdb_id")

添加到 Java 代码中，您是在对 Spring Boot 说，当他在数据库中保存或检索字段

imdbId

时，使用名为

imdb_id

的列。

如果这个建议解决了您的问题，也许您需要对以 camelCase 编写的所有字段执行相同的过程。
