415不支持的媒体类型(JAVA + Angular + RestFUL JSON)

我的一个控制器存在问题。当我使用(jason内容类型)从angular发送(POST)数据到java控制器时,我看到主题中可见的错误。所以我无法从服务器上获取响应。控制器捕获此请求很好,因此在这种情况下,书籍正确地添加到数据库。 Firebug显示404错误,但当我在Postman中查看时,我看到 415 Unsupported Media Type 。如果控制器正常工作,为什么会出现这种情况。

这是示例JSON:

{"title":"fgthbfgd","authors":[{"author_id":24,"author":"danielle steel"}],"genres":[{"genre_id":1,"genre":"Dramat"}],"description":"rthg","path_image":"19296.png"}

这是控制器:

@SuppressWarnings("finally")
    @RequestMapping(value = "/rest/book", consumes = "application/json", produces = "application/json", method = RequestMethod.POST)
    public MessageDTO addNewBook(@RequestBody BookDTO newBook) {
        MessageDTO message = new MessageDTO();
        try {
            bookService.addNewBook(newBook);
            message.setCheck(true);
        } catch (BookTitleException e) {
            message.setCheck(false);
            message.setDescription("Ksiązka o tym tytule juz istnieje.");
            e.printStackTrace();
        } finally {
            return message;
        }
    }

这是BookDTO

public class BookDTO implements Serializable{

    private static final long serialVersionUID = -5057364006691079475L;

    private Integer id;
    private AuthorEntity [] authors;    
    private String description; 
    private GenreEntity [] genres;  
    private String title;
    private String path_image;
    private double rate;
    private Integer progressBar;
    private boolean flagRate;
    private double userRate;

    /* geters and seters */
}

这是Angular代码:

var bookResource = $resource( $rootScope.restUrl + 'book');

var book = {
            title : $scope.title,
            authors : $scope.author,
            genres : $scope.genre,
            description : $scope.description,
            path_image: null
        }

service.addNewBook = function(book){
        var deferred = $q.defer();
        bookResource.save(book)
            .$promise.then( function(data){
                deferred.resolve( data );
            }, function(){
                deferred.reject("Error during adding new book.");
            });
        return deferred.promise;
    }

这只是我的一个问题。在另一个案例中,所有工作正常。

您有一个415错误,因为您发送的请求没有正确的content-type标题

var bookResource = $resource( $rootScope.restUrl + 'book',{}, {
    save:{
        method:"POST",
        headers:{'Content-Type':'application/json; charset=UTF-8'} 
    }
});

我希望它能解决你的问题
