我正在使用：graphql-spring-boot 和 graphql-java-tools 來實現。電影.graphqlstype Movie {    id: Short    name: String    poster: String    releaseDate: String    runtime: String    storyline: String    rated: String    rating: String    inserted: String}type Query {    movies: [Movie]    movie(id: ID!): Movie}電影模型@Entitypublic class Movie {    private Short id;    private String name;    private String poster;    private Date releaseDate;    private Time runtime;    private String storyline;    private String rated;    private double rating;    private Timestamp inserted;}如您所見，我與其他模型沒有關系。最后是實現GraphQLQueryResolver的類@Componentpublic class Query implements GraphQLQueryResolver {    @Autowired    private MovieRepository movieRepository;    public List<Movie> movies() {        return this.movieRepository.findAll();    }    public Movie movie(Short id) {        return this.movieRepository.getOne(id);    }}以下查詢工作正常：{  movies{    name    rating  }}但是這個查詢：{  movie(id: 1){    name  }}給了我以下錯誤：獲取數據（/電影/評級）時出現異常：無法初始化代理 [com.example.demo.model.Movie#1] - 無會話
