Question

我将Spring Boot和MongoDB用于个人项目，以创建电影和视频游戏数据库。我有检索每个类别的最新五个条目的方法。当我在本地Tomcat和MongoDB服务器上进行测试时，这些方法可以按预期工作。但是，当我部署到tomcat服务器并连接到MongoDB服务器时，检索最近五个条目的方法始终返回一个空数组。这是代码：

存储库：

public interface MovieRepository extends MongoRepository<Movies, String>{
    public List<Movies> findAllByOrderByTitleAsc(Pageable pageable);

    @Query("{'title': {$regex: ?0, $options: 'i'}}")
    public List<Movies> findByTitle(String title);

    public List<Movies> findTop5ByCreatedAtLessThan(String currentDate);

    public Movies findMovieById(String id);

    public List<Movies> findByPlatformsIn(List<String> platforms);
}

控制器：

@RestController
@RequestMapping("/api")
public class MovieController {
    @Autowired
    private MovieRepository movieRepository;
    @Autowired
    private MapValidationErrorService mapValidationErrorService;
    @Autowired
    private CurrentDateService currentDateService;

    @GetMapping("/movies")
    public List<Movies> findAllMovies(@RequestParam(value="page",       defaultValue="0")int page) {
    return movieRepository.findAllByOrderByTitleAsc(PageRequest.of(page, 20));
    }

    @GetMapping("/movies/{movieId}")
    public Movies findMovieById(@PathVariable("movieId") String movieId) {
        return movieRepository.findMovieById(movieId);
    }

    @PostMapping("/movies")
    public ResponseEntity<?> saveMovie(@Valid @RequestBody Movies movie, BindingResult result) {
        ResponseEntity<?> errorMap = mapValidationErrorService.mapvalidationService(result);

        if (errorMap != null) return errorMap;

        movie.setId(null);

        Movies newMovie = movieRepository.save(movie);

        return new ResponseEntity<Movies>(newMovie, HttpStatus.OK);
    }

    @PutMapping("/movies")
    public ResponseEntity<?> updateMovie(@Valid @RequestBody Movies movie, BindingResult result) {
        ResponseEntity<?> errorMap = mapValidationErrorService.mapvalidationService(result);

        if (errorMap != null) return errorMap;

        Movies updatedMovie = movieRepository.save(movie);

        return new ResponseEntity<Movies>(updatedMovie, HttpStatus.OK);
    }

    @DeleteMapping("/movies/{movieId}")
    public void deleteMovieById(@PathVariable("movieId") String movieId) {
        movieRepository.deleteById(movieId);
    }

    @GetMapping("/moviePlatforms")
    public List<Movies> findMoviesByPlatforms(@RequestParam(value="platform") List<String>platforms) {
        return movieRepository.findByPlatformsIn(platforms);
   }

    @GetMapping("/newFiveMovies")
    public List<Movies> findTop5ByCreatedAt() {
        String currentDate = currentDateService.getCurrentDate();

        return movieRepository.findByCreatedAt(currentDate);
    }
}

我已将find前5种方法更改为使用@Query批注，但结果相同。控制器和存储库中的所有其他方法均按预期工作。我曾尝试在Mac和MongoDB Atlas上使用MongoDB。任何帮助将不胜感激。

Answer 1

我发现我作为参数发送的日期格式错误。日期被存储为“ M / d / yyh：mm a”，但我发送的是“ M / dd / yyyy hh：mm a”。

Spring Boot MongoDB findTop5返回空数组
