我的REST API消费者应用程序不断出现whitelabel错误页面

问题描述

我有一个Spring Boot应用程序,我在其中添加了rest API。当我仅将其与“ Movies App”一起使用时,它的效果很好。但是,我创建了第二个应用程序,该应用程序需要使用其余API的两个端点。

  1. 在特定年份上映的电影
  2. 由特定导演执导的电影

我现在正在处理第一个,而较早时它遇到了未发现的错误,我已解决了这个问题,现在我只是遇到了whitelabel错误。它似乎并没有消耗数据。我不确定我刚才输入的内容有误还是我的整体方法不正确。

因此,当我与Movies项目同时运行消费者应用程序时,我应该能够进入浏览器并放入localhost:8080 / api / films {releaseYear},它应该返回所有电影。页面上的那一年。因此,例如,如果releaseYear是2015,我将放入localhost:8080 / api / films / 2015并查看数据库中存储的当年在Json发布的电影。

My domain (Film.class) 
@Setter
@Getter
@NoArgsConstructor
@AllArgsConstructor
public class Director {
    private int directorId;
    private String directorFirstName;
    private String directorSurname;
    private List<Film> films = new ArrayList<>(); 
    
    }

其余消费者中的我的FilmController:

@Controller
@Slf4j
public class FilmController {
    @GetMapping("/films/{releaseYear}")
    public String showFilmsByYear(@PathVariable(name="releaseYear") int releaseYear,Model model)
    {
        try {
            RestTemplate restTemplate = new RestTemplate();
            String URL="http://localhost:8080/api/films/{releaseYear}";
            ParameterizedTypeReference<List<Film>> listofFilms = new ParameterizedTypeReference<List<Film>>(){};
            ResponseEntity<List<Film>> responseEntity = restTemplate.exchange(URL,HttpMethod.GET,null,listofFilms );
            List<Film> films = responseEntity.getBody();
            log.info(responseEntity.getHeaders().toString());
            model.addAttribute("films",films);
            return "films";
        }
        catch (HttpClientErrorException ex) {   
            model.addAttribute("exception",ex); //exception isnt handled because hitting whitelabel
            return "notfound";
        }
        
    } 

我的FormObject:

@Setter
@Getter
@NoArgsConstructor
@AllArgsConstructor
public class FilmForm {

    @Size(min=2,max=20)
    @NotEmpty
    @NotBlank
    private String filmName;
    //add minimum year and max year (won't always be 2020,but can't allow films that are further then current year)
    @PastOrPresent
    @NotBlank
    @Min(1888)
    private int releaseYear;
    @NotEmpty
    private Director director;
    
}

我的html:

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
    <div th:insert="fragments.html :: head"></div>
    <body>
        <header>
            <div th:insert="fragments.html :: menu"></div>
            <h1><span th:text="#{films.heading}"></span></h1>
        </header>
        <main>
            <table>
            <tr>
                <th th:text="#{films.id}"></th>
                <th th:text="#{films.filmName}"></th>
                <th th:text="#{films.directorFirstName}"></th>
                <th th:text="#{films.directorSurname}"></th>
                <th th:text="#{films.releaseYear}"></th>
            </tr>
            <tr th:each="film,iterationCount : ${films}" th:class="${iterationCount.even}? 'even'" th:object="${film}"  >           
                <td th:text="*{filmId}"></td>
                <td th:text="*{filmName}"></td>
                <td th:text="*{director.directorFirstName}"></td>
                <td th:text="*{director.directorSurname}"></td>
                <th th:text="*{releaseYear}"></th>
            </tr>
            </table>
        </main>
    </body>
    <footer th:insert="fragments.html :: footer">
    </footer>
</html>

它不需要表单,因为它不使用html,但我只是想为了清楚起见就包括在内。

我想在Movies项目中访问的控制器是:

@RestController
@RequestMapping("/api")
public class RestControllerDir{
    @Autowired
    FilmService filmService;
    @Autowired
    DirectorService directorService;


    @GetMapping("directors")
    public List<Director> myRestDirectors(){
        return directorService.listInAlphabeticalOrder();
        }
    
    @GetMapping("filmsByDirector/{id}") 
    public List<Film> myRestFilms(@PathVariable("id") int id)
    {
        return directorService.findDirector(id).getFilms(); //returns the films directed by a particular director
    }
    
    @GetMapping("viewFilmsByYear/{releaseYear}") 
    public List<Film> myRestFilmsYear(@PathVariable("releaseYear") int releaseYear)
    {
        return filmService.findFilmsByReleaseYear(releaseYear); //returns the films released in a particular year
    }
